Common Mobile Home Plumbing Issues and How to Fix Them

Before we list the most common mobile home plumbing issues and the corresponding ways to fix them, let us first describe the main difference between the plumbing systems of mobile homes and site-built houses.

 

Supply Line Location 

 

The difference primarily stems from the way they are constructed. In site-built houses, the plumbing systems often run inside the walls, whereas they are buried under the floor in mobile homes. 

 

Common Mobile Home Plumbing Issues and How to Fix Them

 

While you can DIY some of the plumbing problems mentioned here, remember that it is safer and more cost-effective to hire a professional plumber in some situations. 

 

Leaking showerhead

 

In most cases, the problem is caused by damaged or corroded inner seals or other parts in the shower valve. Occasionally, the issue also stems from hard water deposits, which is creating a blockage. 

 

To fix it, shut off the water main to the whole house before unscrewing the showerhead from the pipe. Next, check if the rubber-O ring and gasket are corroded, which you can easily buy from your local hardware store. 

 

If hard water deposits cause the leak, clean the showerhead and reattach it to the pipe. 

 

Low water pressure in the shower 

 

Oftentimes, you can address the issue by simply tightening the loose valves or installing a new showerhead. 

 

Leaking faucet

 

The cause of leaking faucets varies; it can be from corrosion, damaged gaskets or O-rings, and mineral deposits causing the blockage. 

 

You can fix a leaking faucet yourself, but you must first know which model you have because it will determine how you disassemble and assemble the parts back. There are four kinds of faucets: ball, ceramic disk, and cartridge. 

 

In most cases, the leak is caused by a defective O-ring or neoprene seal, which you can fix. But if you have a ball-type faucet, you may want to buy a replacement kit instead of finding the defective parts, which can be a bit tricky because the faucet has a complicated design and multiple parts. 

 

Clogged sink drain 

 

Hairball, debris, and soap buildup can clog your sink drain. But before you grab a store-bought chemical drain cleaner, take note that it is too corrosive even for your pipes. 

 

If the clog is just caused by soap buildup, pouring boiling water or baking soda followed by an equal amount of white vinegar might be enough to solve the problem. But in severe cases, you may need to call a professional who can use drain snakes to unclog your drain. 

 

Clearing out the interior of the P-trap can also address the slow-draining sink. To do this, place a bucket between the plumbing to catch any runoff. Then, loosen the two nuts connecting the P-trap to the drainpipe to start the cleaning process. 

 

Backflow in the bathtub when the toilet is flushed 

 

Backflow into the bathtub happens because it is the lowest part of your plumbing system. To fix this problem, you’ll need a closet auger, which is similar to a drain snake because it also has a cable and rod system that drills and breaks out the clog. 

 

Running toilet 

 

The most common cause of a running toilet is a defective or worn-down flapper, which is the part that pulls up the chain every time you flush, allowing the water to release into the bowl. 

 

If you have a worn-out flapper, turn off the water, remove it, and take it to your local hardware store to find an exact replacement. If you can’t find a perfect match, try to pick the closest one, an adjustable type, or a universal design.
