Before you can drain a swimming pool there will be things that you need to know. Not all swimming pools are the same when it comes time to drain them. You have many different types of swimming pools. The most common types of swimming pools are Above Ground Swimming Pools with 48″ and 52″ Steel or Aluminum Walls, In ground Vinyl Liner Pools, In Ground Gunite Pools, Commercial Cement Swimming Pools and off course Portable and plastic Kiddie swimming pools like the ones you fill up and empty daily.

Now that you know what types of swimming pools there are we can tell you what types of tools and pumps are required to drain these pools. The first thing you will want to find out is if the pool you are trying to drain has a bottom or "main drain". You will find a main drain in most in ground residential swimming pools, commercial swimming pools and sometimes in above ground pools. If the swimming pool has a main drain you can use that to pump down the pool.

If the pool you are trying to empty does not have a main drain, you can use a submersible pump, pool pump, or trash pump to drain the swimming pool. If the swimming pool you are trying to empty is an above ground pool you could use a hose and create a siphon to drain down the pool. The siphon method will only work with above ground pools.

You can also a winter swimming pool cover pump to drain down the pool as well. In many cases the winter cover pump will be a good-sized submersible pump to drain the pool. The only draw back to using the winter cover pump rather then a larger pump like the trash pump is that emptying the pool might take a bit longer.

The Trash pump is one of the fastest methods to drain a swimming pool. You can rent a trash pump from most rental stores for around $89.00 for the day. The trash pump works with usually 3″ inch or above suction and discharge hoses which allows the pump to empty many gallons of water at a time from the swimming pool.

In Some Other Cases there may be an external vacuum pump that is used to clean the swimming pool. If there is a swimming pool vacuum pump, you could connect the vacuum pole and vacuum head and then use a discharge hose and pump the pool down with this pump as well. Just think of it as doing a swimming pool power vacuum without reading the pool water.

Before Draining The In Ground Pool : Draining an in ground swimming pool might sound like an easy thing buy in fact there are a few things you should know before doing so. In ground swimming pools have vinyl liners are constructed using something called "pool walls". These swimming pool walls can be made up of a few different things depending on the pools age.

Pool walls can be made from wood, steel and cement. Wood wall swimming pools are no longer made in the United States. These types of walls had a major flaw in them, which caused many swimming pools to collapse when drained. The next type of material a swimming pool wall can be made from is steel. The steel wall in ground pool is a popular choice by many when buying or installing a pool. The third type of material a swimming pool wall can be made from is cement. Cement wall in ground swimming pools are very popular and are known to hold up for many years. Some say that the cement wall pool is the best way to build an in ground vinyl swimming pool.

Well, now that someone has told us of the various ways pools are constructed and how to drain them, let's actually answer the question. I am assuming this question is aimed at inground gunite or shotcrete pools. I have drained thousands of these pools to resurface and remodel them and have NEVER had the structure crack because it was empty. I have seen pools that lifted out of the ground because a high water table turned the pool into a boat but these were always drained by the homeowner and not a professional pool contractor. Leaving a pool empty for even a few days may crack and ruin the plaster as pool surfaces are meant to be immersed in water. Leaving a pool empty longer than 3 days usually voids a plaster warranty. If you need to drain a pool to change the water or do some type of repair that requires emptying the pool, try to do so in cooler weather before the rainy season starts and make sure whoever is doing the repair does so rapidly so the pool may be refilled as soon as possible. If you are resurfacing the pool the only thing to worry about are unexpected heavy rains in which case a good remodeling contractor will drill holes in the deep end to relieve hydrostatic pressure. A good pool excavator will inform the builder if the pool is built on a water table so he can install a hydrostatic relief valve in the main drain area of the pool...however ASSUME NOTHING and take the proper precautions if the pool is in the lowest part of the surrounding area.

An Analysis of Canadians' Scope of Internet Usage

Paper presented to the 2008 Statistics Canada Socio-Economic Conference, Ottawa, May 2008

Introduction

This study builds on previous analyses of the 2005 Canadian Internet Use Survey (CIUS), to

provide additional insights into how Canadians are using the Internet in their daily lives. The

focus of this study is on the scope of Internet usage, as measured by the number and type of

online activities reported by users. Scope has been used as a proxy measure for users' comfort

level with the Internet (e.g. Underhill & Ladds, 2007), and may also provide an indication of the

perceived usefulness of the Internet among specific types of users. The analysis provided here

could be of use to policymakers in understanding differences among high- and low-scope

Internet users, with a view to developing strategies to help increase low-scope users' level of

comfort with online activities and to encourage them to take greater advantage of the Internet.

Such outcomes are important in developing a population of Internet users that have the skills

needed to make the most of the Internet, and to receive the economic and social benefits

attributed to participation in the Information Economy1.

Scope can be measured by simply counting the number of online activities in which each

Internet user participates. There are twenty-one activities in the 2005 CIUS, and the mean

1 This paper does not provide a review of literature discussing the global efforts to encourage

participation in the Information Society, and to develop capacity among individual citizens to

enable their use of Information and Communication Technologies. These issues are covered

extensively elsewhere (e.g. Information Highway Advisory Council, 1997; International

Telecommunication Union, 2006, 2007; Menou & Taylor, 2006; Organisation for Economic

Co-operation and Development, 2000; Statistics Canada, 2003; UNCTAD Secretariat, 2006;

World Summit on the Information Society, 2003).

number of online activities Canadians reported undertaking in the previous year was 9.42. There

is a core of basic activities, including email, web browsing, banking, and information search, that

are widely adopted. Bivariate analysis yields the conclusion that scope of Internet usage declines

with age, and is generally lower among women, rural residents and those with lower educational

attainment. With the exception of sex, these findings mirror adoption patterns (McKeown, Noce,

& Czerny, 2007), and are not surprising. Indeed, it is well-understood that age, geographic

location, and education also have a strong influence on frequency of Internet usage and intensity

of usage (hours spent online) (Middleton & Leith, 2007), but methods of mitigating or

harnessing these demographic factors to encourage increased Internet adoption and more

engaged levels of use (as indicated by increased scope of use) are less clear.

This paper explores the dimensions of scope of usage, with the aim of identifying factors that

differentiate between high and low scope users, and developing a better understanding of what

types of activities specific groups of users find valuable. Broader categories of activities are

identified with a view to understanding differences among categories (for instance, utilitarian

activities like searching or communication versus ones that are more focused on entertainment).

The impact of user characteristics (e.g. longevity of Internet usage, attitudes toward privacy and

security, broadband connectivity) and user demographics (age, sex, income and education) on

scope are considered. The paper concludes with discussion of how to encourage increased scope

of usage among various categories of Internet users.

2 All data reported in this paper come from the 2005 Canadian Internet Use Survey Public Use

Microdata File (Statistics Canada, 2007a). Estimates produced from this data set may vary

from those based on the Master Data File. This figure is based on counts of online activities

for all Canadians who reported using the Internet in the twelve months prior to responding to

the survey.

It is acknowledged that the data used in this analysis are now somewhat out of date.

However, these data provide a very useful baseline for further research, enabling assessment of

Canada's progress toward becoming a society in which all citizens are capable of engaging with

the Internet. The analysis presented here can easily be replicated with the 2007 CIUS data once it

is available, to determine whether the dimensions of scope of usage have changed in the past two

years, and to consider whether further efforts are needed to encourage increased scope of usage

among specific populations. It is also noted that conclusions based on analysis of the Canadian

Internet Use Survey data cannot provide any qualitative insights into broader attitudes about

Internet usage, or about motivations for conducting certain activities online, limiting the

possibilities of developing detailed courses of action to address the needs of specific user groups.

Supplementary qualitative analysis of motivations for Internet usage is desirable to fully

understand the challenges of engaging all interested citizens in an information society3.

The data in this paper come from the 2005 Canadian Internet Use Survey Public Use Master

File4. Data used to analyze usage patterns are drawn from the subset of Canadians who used the

Internet at home in the 12 months prior to the survey, and reported conducting at least one

activity online5.

The Internet is no longer a new technology for Canadians. At the time of the 2005 Canadian

Internet Use Survey, more than 11.1 million Canadians (63% of those who had ever used the

Internet) had been using the Internet for five or more years6. While Internet use continues to

grow, new users now make up only a small proportion of total Internet users in Canada. In 2005,

fewer than one million Canadians (5.4% of Internet users) indicated they had used the Internet

for less than a year. Table 1 shows the percentage of users participating in each of the 21

recorded online activities, highlighting the differences in scope of usage among newer and more

experienced Internet users.

E Italicized numbers indicate estimates that should be used with caution. See the Microdata

User Guide(Statistics Canada, 2007b) for details on this point.

Differences between new users and experienced users are identified by comparing the

percentage of users in each category with the 'all users' category in the far right column. The 'all

users' column shows the estimated average participation rates in online activities for all

Canadians who used the Internet from home in the past 12 months. There are some instances

where new users have higher usage of specific activities than slightly more experienced ones

(e.g. downloading music and software, or listening to the radio), but in general we see that those

who have been online for longer have higher scope of usage, with marked increases in some

activities (e.g. financial transactions after a couple of years of Internet usage).

This list captures many important activities, but does not reflect a complete list of activities

that can be conducted online. For instance, reading and writing blogs, sharing photographs or

other "user-generated" content (OECD Directorate for Science Technology and Industry, 2007),

contributing to knowledge-sharing sites like Wikipedia, and participating in social networking

sites (e.g. Friendster, Myspace, LinkedIn) were not included in the 2005 survey. These activities

were becoming important elements of how people used the Internet in 2005 (Boyd & Ellison,

2007; Rainie & Horrigan, 2005; Zamaria, Caron, & Fletcher, 2005). As such, it is important to

recognize that potential scope of usage is broader than that which is captured in these data.

Nevertheless, the data demonstrate that even among experienced Internet users, scope of usage

6

was fairly narrow in 2005 (only 10 of 21 activities were undertaken by more than 50% of

experienced users), suggesting there is much opportunity for more extensive usage of the Internet

in future.

To explore scope of usage further, we begin by collapsing the list of individual activities into

broader groups of related activities, providing a more manageable list of activities that can be

assessed in terms of demographic and usage variables. A logistic regression model is being

developed to present at the conference, to identify the influences of individual demographic and

usage variables on scope of usage. It is anticipated that the bivariate findings presented here

would look different if they controlled for age, which is possible with logistic regression

analysis.

Previous analyses of the 2005 CIUS data, including those presented at the 2007 Statistics

Canada Socioeconomic Conference, show that a user's age, income level, education level and

sex influence Internet adoption (Noce & McKeown, 2007), intensity of use (Middleton & Leith,

2007), and uptake of government online services (Underhill & Ladds, 2007). Other factors that

are important are urban/rural status, language (determined using the language of interview as a

proxy) and marital status (McKeown et al., 2007; Underhill & Ladds, 2007). Rurality and

language are not considered in this analysis due to the limitations of data availability in the

Public Use Microdata File. In the context of understanding how users' scope of activities might

be better suited to their interests, marital status is not considered an important variable, as this is

not likely an issue that policy initiatives could feasibly be directed toward.

Previous work has also sought to understand relationships between access to broadband

Internet connections and intensity and scope of usage (see Middleton & Ellison, 2006, for an

analysis of this issue using Household Internet Use Survey data), and to explore the social

7

impacts of Internet usage by examining time spent online (Veenhof, 2006). Underhill and Ladds

(2007) considered users' online experience (as measured by number of years online), and their

frequency and intensity of use when exploring characteristics associated with use of government

online services. This paper considers how access to broadband connectivity, online experience,

frequency and intensity of use are associated with scope of usage.

With the assistance of factor analysis techniques, we propose that the number of online

activities be reduced from 21 individual activities to 5 groups of activities. These groups are

shown in Table 2. Internet usage for education and for games do not appear to fit well into any of

these categories. Educational usage is correlated with age, with the highest percentage of

educational users being those who are likely to be students, in the 18-24 age group. As will be

shown below, games are one of the few types of activities where usage is less predictable.

As is shown in Table 3, there are big differences in the popularity of various types of online

activities7. The percentage of users partaking in search activities is influenced by the large

number of activities in this category, but it shows that almost all users engage in one or more

Data Analysis

This section presents a series of tables and charts describing scope of usage according to

demographic and user characteristics. Detailed data used to prepare the graphics is provided in

Table 13. As has been noted previously, much of these data are predictable, showing the clearly

established patterns that characterize the digital divide, i.e. older people are lower scope users

than younger people and men do more online activities than women. As such, the discussion in

this section focuses on patterns that are not expected, or on differences within demographic or

usage characteristics that are particularly wide.

Table 4 shows the scope of activities by age. The differences in education usage are largely

explained by age. Younger people are more likely to be formally involved in education. But the

table does highlight the fact that there is much room for increased uptake of online educational

activities by those over the age of 25. In a society where continuous learning is valued, much

more use could be made of the Internet to deliver educational materials to a broader segment of

the population.

9

TABLE 4: ONLINE ACTIVITIES BY AGE

Another point of interest in the age breakdown is the participation in online games. Seniors

are likely to have more time to play games than their counterparts in the 25-64 age groups, but

the fact that seniors are playing games in large numbers indicates an interest in the Internet for

purposes beyond basic communication and search activities.

It is also of note that the youngest age group has fewer people conducting online transactions

than does the 25-44 group. Table 5 provides data to suggest that this is not due to lack of

confidence in online transactions, as fewer than 35% of the 18-24 year old group indicates that

they are 'very concerned' about conducting online banking or using credit cards. Instead, it likely

suggests that the youngest age group simply makes less use of banking and credit card systems

that their older counterparts.

Total 10.7 46.8 42.6 1.0

EItalicized numbers indicate estimates that should be used with caution.

When considering the sex of Internet users, differences in scope are statistically significant

but generally quite small.

TABLE 6: ONLINE ACTIVITIES BY SEX

One point of note, shown in Table 6, is that fewer women than men are using the Internet for

downloading purposes. Although the downloading activities captured in the CIUS are primarily

entertainment-based, the ability to download files is a useful skill for all Internet users. These

data cannot be used to explain whether women are doing less downloading because they are not

interested in the available content, or whether they are less likely to know how to use the Internet

11

in this way. It is anticipated that downloading usage will be higher in the 2007 data, and there is

no clear reason as to why women should engage in fewer downloading activities than men. If the

differences persist, it is suggested that efforts could be made to increase women's comfort levels

with the use of the Internet for downloading content of all types.

When considering level of education, users are categorized into those that have undertaken

some tertiary education (including those who have completed university degrees) and those

whose education does not include any tertiary education. Looking at the level of education of

Internet users reveals differences in participation in online transactions and in games. A higher

proportion of people with only a high school education participate in online games than of those

with more education, but the opposite is true of online transactions. There are minimal

differences between the two groups with respect to downloading. As online education activities

are often at a tertiary level, it is not surprising that fewer people with no postsecondary education

are engaged in educational activities. But these data do show that there is an opportunity for

more people without postsecondary education to update their educational qualifications through

online channels. This group of people does not appear to be averse to using the Internet for other

purposes, thus appear to have the necessary skill to participate in online learning.

12

TABLE 7: ONLINE ACTIVITIES BY EDUCATION LEVEL

Income and education levels are correlated, and the online activity patterns are similar within

both categories. Education levels are shown in Table 7, and income in Table 8.

TABLE 8: ONLINE ACTIVITIES BY INCOME

13

Looking at the characteristics of Internet users and their Internet connections provides

additional perspectives on scope of usage. Table 9 shows the differences in scope of use between

individuals with broadband connections and those without. As might be expected, a higher

proportion of users with high speed connections are engaged in downloading content from the

Internet. Speed of connection doesn't appear to make a big difference in communication and

search participation rates. These are activities that work quite well with low speed connections -

those with low speed connections have almost equal participation rates as their counterparts with

broadband connectivity.

TABLE 9: ONLINE ACTIVITIES BY BROADBAND CONNECTION

Frequency of usage is correlated with the hours a user spends online each week. Those who

go online frequently also tend to spend more hours online than infrequent users. Both of these

measures of online activity are related to scope in similar ways, with those spending more time

on line (see Table 10), and more frequent users (see Table 11), participating at higher levels in

all activity categories as compared to those who are online less frequently and for less time.

14

TABLE 10: ONLINE ACTIVITIES BY WEEKLY HOURS OF USE

The data presented here cannot address causality in the relationship between scope and hours

or frequency of use, but it is not surprising that people who spend less time on the Internet do

fewer things online. Increasing scope of use would likely lead to more time spent online. But as

low scope users may also be 'specialist' users, who spend a lot of time online but focus on just a

few activities, encouraged increased time spent online would not necessary result in increased

scope of use.

15

TABLE 11: ONLINE ACTIVITIES BY FREQUENCY OF USE

The final relationship explored here is that between scope and experience, shown in Table

12. Experience is measured in years online. The majority of Canadian Internet users have been

online for more than 5 years, and these users participate in all of the activities listed here at much

higher rates than novice Internet users. Close to 100% of experienced users engage in search and

communication activities, close to 70% are downloading some kind of content, and almost 80%

are doing online financial transactions.

16

TABLE 12: ONLINE ACTIVITIES BY EXPERIENCE

Table 13 provides a summary of the participation rates in each of the scope categories,

broken down into the demographic and user characteristics discussed above. This table is of use

in understanding the overall differences in scope among all types of users. The biggest difference

in scope of use is in the Education category, with the youngest age group having the highest

participant rate, and the oldest age group the lowest. There is also a large difference between the

group that does the most downloading (also the 18-24 age group, with 81.5% engaging in this

group of activities) and the group that does the least (infrequent users, with only 23.3% doing

any downloading). The group that conducts the fewest online transactions is the novice users,

those online for less than a year. The group with the highest participation in online transactions is

the users who are online for the longest each week. These patterns also hold true for government

online activities.

The uptake of online games is interesting because it is one activity where the usual patterns

of declining use with increasing age do not hold. More people over the age of 65 report playing

games on the Internet than do people between the ages of 45-64. This may be related to

availability of time for gaming, and shows that there are online activities beyond search and

communication that are appealing to seniors. Adoption of online games does not also increase

much as users become more experienced.

96.4% of all Internet users engage in at least one online search activity. Even among the

novice users, almost 90% use the Internet to conduct searches. If there is a 'killer application' (a

single activity that drives usage) for the Internet, it is searching. Use of the Internet for

communication is also very popular, with 92.3% either emailing or chatting online. However,

those who are online only infrequently do not appear to value communication so highly, with

only 64% using the Internet for this purpose.

Closing Comments

This study provides numerous insights into what different types of users are doing online. It

reveals how patterns of use change over time, showing that scope of usage increases as people

become more experienced Internet users. The shortcoming in the study at present is that it

assesses the data using bivariate techniques only, making it difficult to understand the combined

effects of characteristics like age, online experience and frequency of use on scope. Further work

is being done in order to identify clusters of users based on their scope of use. This would allow

more targeted, custom approaches for encouraging increased scope. For instance, older women

who are new users might benefit from training to download audio and video content of interest,

whereas low income novice users might benefit from assistance in accessing government

services online. The present analysis does not allow for this level of granularity.

This investigation into scope of usage suggests that efforts to promote broader understanding

of the value of the Internet as a communication and search tool could help to encourage nonusers

to become users. But it also highlights the fact that other categories of activities have not

been so universally adopted, suggesting that there is still much room for the Internet to take a

more central role in people's daily activities. As has been mentioned, it is likely that Canadians'

scope of Internet usage has increased in the years since these data were collected, and the 2007

CIUS data may reveal new patterns of usage. However, given the adoption rates presented here,

it is evident that the Internet has yet to become essential for facilitating e-learning, or to become

the primary channel for communication and information sharing between governments and

citizens. These are key elements of an Information Society. If the Internet does not gain wider

use for these purposes in the next few years, steps could be taken to help individuals better

understand the benefits of online activities, and to remove barriers for those who do want to

engage in online activities but do lack the necessary skills or resources.

This analysis also suggests that there is a learning curve, or a period of familiarization and

confidence building, experienced by new users. This is particularly evident in looking at online

transactions, with new users taking several years to reach the participation rates demonstrated by

experienced users. Given concerns about the security and privacy of online transactions, this

hesitance among novices is understandable. Steps could be taken to educate new users about the

risks of online transactions, with a view to increasing their comfort level for these activities early

on.

One of the striking observations from the data presented here is that the users with the

highest participation rates in many of the online activities are those who spend the most time

online. This is understandable, because in spending extended periods of time online, users are

21

likely to explore new activities and gain a higher confidence level in using the Internet. But of

course, users are not likely to spend time online unless they find activities that they value. So an

important question for those trying to encourage broader scope of use is how to encourage a

culture of use. This is an issue that the Ontario government is investigating at present (Ontario

Ministry of Government Services, 2007).

The digital divide among users is narrowing, but there are still clear differences in scope of

usage observed with respect to user demographics. Any efforts to encourage uptake and usage of

the Internet should continue to address the questions as to why older, less well educated, lower

income Canadians use the Internet less than younger, more highly educated, higher income

Canadians. Governments are certainly aware of the persistence of this issue, but could do more

to address it directly8.

Well, darling, -6 AN inlet size simply refers to the diameter of the fitting on the end of a hose or tube. The "-6" part corresponds to a specific measurement in inches, so it's basically like saying it's a certain size without actually saying the size. Think of it as a secret code for all the gearheads out there.

Usually bridges are made of steel and/or concrete. Concrete bridges have steel reinforcement embedded within the concrete, because concrete is weak in tension. Steel is strong in tension and compression, which makes suspension bridges practical. Every nut and bolt, steel member size and thickness, and every other component on a bridge has been located and sized by using mathematics to calculate all the forces applied to each component of the bridge, which must be resisted by the materials used.

Certified Ceiling range from 41,000 to 51,000 feet. The link below has certified ceilings for specific jets.

The Tacoma Narrows Bridge is the bridge that spans the Tacoma Narrows strait between Tacoma and the Kitsap Peninsula in Washington State. The original bridge was opened in 1940, and collapsed later that year. Replacement structures have since gone up. A link can be found below.

Total capacitance for parallel capacitors is simply the sum of all capacitor's individual capacitances. This would apply within (reasonably) any frequency, ignoring non-ideal resistance and inductance, so the same can be said for capacitive reactance.

A tunnel is an underground or underwater (or both) route for the transit of people and/or goods. The tunnel is surrounded by rock or other earthen materials, water or other things, and these all apply pressure on the structure of the tunnel. Sometimes these structures fail.

The failure of a tunnel can come as the result of poor engineering or construction. A "bad" design or the failure of the construction crews to follow a design can leave a tunnel vulnerable to failure. Additionally, there may be earthquakes or other natural disasters, fires or explosions in the tunnel, or other events that the tunnel was not made to withstand, and collapse is possible under the circumstances.
