Do it Yourself Mobile Home Plumbing

Mobile home plumbing is very different from conventional home plumbing. First, different piping is used. Secondly, there are many different techniques employed in a mobile home plumbing system due to different space requirements and code restrictions. Some plumbers will not commit to work on mobile homes, so if you need a new installation in your home, one option is to do it yourself.

Plumbing Fixtures in Mobile Homes

Plumbing a mobile home is different than conventional homes.

Before working on plumbing in a mobile home it is important to know what you are getting into. The types of plumbing fixtures used in mobile homes may differ from conventional homes. So, parts are sometimes hard to find. For instance, plastic pipes are now used in mobile homes. This includes PEX and CPVC pipes. These pipes are easier to work with because they are cut with a hack saw and use plastic fittings instead of hot soldered connections. This type of pipe may be available at a home improvement store in your area. If not, a mobile home repair contractor will point you in the right direction.

Where to Begin

The second thing to know about your home is where the shut off valve is. The first step in any DIY plumbing project is to turn off the water supply. Most shut off valves are located in the home, near the main water pipe. There are two in most mobile homes. The main one brings water directly into your home and is located somewhere in the floor. Check for the other one near the water heater. Once the main line is shut off, no water will flow through the pipes and the plumbing is safe to work on.

Replacing Water Pipes

Much of the DIY plumbing in a mobile home involves replacing water pipes. Damaged pipes cause leaks that can lead to water damage. The plastic pipes are replaced by removing the damaged section and reinstalling a fresh section. Cut the pipe using a pipe saw and then install a new joint. Apply pipe cement or sealant to the joint and the pipe, then insert the pipe into the joint. Most pipes are located under the floor of a mobile home. When replacing any length of pipe, inspect the entire pipe for damage. In some cases, it may be wise to replace the entire pipe.

Joints and Fixtures

The fixtures in a home connect directly to plastic pipes in most cases. The vertical pipes are connected to the floor water mains with a 90 degree elbow joint or a flexible, accordion style pipe. When replacing these pipes use matching joints and couplers and apply the proper cement to each. Check the cement label to ensure it is designed for the type of pipe you are using. The pipe grade is listed on the side of the pipe.
