In plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as the S-bend invented by Alexander Cummings in 17…75 but became known as the U-bend following the introduction of the U-shaped trap by Thomas Crapper in 1880. The new U-bend could not jam, so, unlike the S-bend, it did not need an overflow. The bend is used to prevent sewer gases from entering buildings. In refineryapplications, it also prevents hydrocarbons and other dangerous gases from escaping outside through drains. The most common of these traps in houses is referred to as a P-trap. It is the addition of a 90 degree fitting on the outlet side of a U-bend, thereby creating a P-like shape. It can also be referred to as a sink trap due to the fact it is installed under most house sinks. Because of its shape, the trap retains a small amount of water after the fixture's use. This water in the trap creates a seal that prevents sewer gas from passing from the drain pipes back into the occupied space of the building. Essentially all plumbing fixtures includingsinks, bathtubs, and toilets must be equipped with either an internal or external trap. Because it is a localized low-point in the plumbing, sink traps also tend to capture heavy objects (such as jewelry) that are inadvertently dropped into the sink. Traps also tend to collect hair, sand, and other debris and limit the ultimate size of objects that will pass on into the rest of the plumbing, thereby catching over-sized objects. For all of these reasons, most traps can either be disassembled for cleaning or they provide some sort of cleanout feature.
Polyethylene and polybutylene are two common types of flexible tubing used in plumbing, and both are used in hot and cold water supplies in place of traditional copper lines.
Answer some what, some places had a hand pump in side, in some cities yes, not in the country, they used hand pumps or wells, and out houses,
Copper is easy to use and work with. The minerals in water generally do not build up on copper as easily as on galvanized steel. After WWII copper was relatively cheap and ava…ilable in great quantities so the plumbing products industry changed to it as its standard pipe. Now copper is much more expensive and new materials such as plastics are being used. Copper does not rust or perish easily, making it ideal for use in any climate. Copper is also heat and cold resistant and swells and contracts much less than other materials when its temperature changes. Copper resists damage from minor home fires much better than plastic.
Mainly bricklayers, but also anyone else that need to know if something is perfectly vertical in all planes (from all directions).
Answer Yes and gas for lighting and there was even venting and soil and waste lines and storm drainage
When the local codes allow its use on the piping as some codes do restrict the use of tape
The man came over to my house to plumb my toilet We have a long way to go to plumb the depths of the words.
Because it lasts and is very versatile and can be used for a variety of plumbing applications with amazing results
Answer Wikipedia says, " 26th century BC: Flush toilets were first used in the Indus Valley Civilization. The cities of Harappa and Mohenjo-daro had a flush toilet in a…lmost every house, attached to a sophisticated sewage system." Let's see, about 4600 years ago.
Copper is used for most plumbing systems. Alloys such as steel and brass are also often used.
The plumb bob's inventor is lost to history...the name comes from the corruption of the Latin word for lead: Plumbum. Bob has nothing to do with it.
A plumb bob is a weight on the end of a string. It usually has a pointed lower end. It is hung adjacent to or in line with building elements to check whether they are …"plumb" or "true to the vertical". A weight on a string holds the string under tension in a straight line down to the ground because of gravity. A person can move so they can see whether the straight line of the string lines up against the built element, to tell whether it is vertical.
That would probably be lead that you're thinking about.
The plumb bob is useful in establishing vertical for a wall in construction or a doorjamb when hanging a door. It can indicate whether a flue is running true vertical or v…eering off plumb. A plumb-bob or a plummet is a weight, usually with a pointed tip on the bottom, that is suspended from a string and used as a vertical reference line, or plumb-line. It is essentially the vertical equivalent of a water level.
