All clean outs have to be accessible or what is the purpose of installing them?
They can be placed behind an access door or under a floor plate
Water Jetting
A 3 or 4 inch pipe sticking straight up out of the ground? This is the clean out for the sewer line. If sewage is coming out of it, this means the sewer line is clogged or collapsed from there to the main city sewer. If you have a septic tank, the tank is full and needs to be pumped out.
Yes, they can be opened for routine sewer and drain and leader cleaning
The way you ask this question is too broad. Which part of your sewer pipe needs replacing? Exposed pipe in your basement or crawlspace is too simple for you to be asking about. If you mean the sewer pipe that connects your house to the city sewer (generally under the street) you have a big task. Depending on what part of the country you are in, this section of your sewer pipe can be anywhere between 4 feet and 20 feet deep. In either case you'll need a backhoe to dig it up.
The purpose of a sewer pipe is to collect waste from drains and peoples homes and transport it through the sewer system to the sewer plant. There it is treated and the water is recycled.
No. You vent air from a sewer line.
Depending on what kind of sewer, its age, and the utility owner (Storm Sewer, Gravity Sewer, Sewer Forcemain). - Polyvinyl Chloride Pipe (PVC) - Ductile Iron Pipe (DIP) - Fiberglass Reinforced Pipe (FRP) - High Density Polyethelyne (HDPE) - Pre-Stressed Concrete Cylinder Pipe - Asbestos Cement - Clay - Steel
If you are talking about a roof water drain pipe to sewer it is illegal. If you are talking about a sink drain pipe well that is where they all connect to so yea.
Sewer waste
Certainly
ABOVE the sewer line and on an angle away
