Plastic Pipes Rattling When You Flush The Toilet? They May Be Loose

Posted on

When you flush your toilet, do you notice a rattling sound beneath you? If so, there's a good chance the plastic pipes underneath your toilet are a little loose and need to be stabilized. One of the easiest ways to do this is to use spray foam insulation. This substance can not only stabilize your pipe, but also protect it from weathering damage.

Checking If The Pipe Is Loose

Go down into your basement and locate the pipes underneath your toilet. Have someone above you flush the toilet and watch the pipes as the water pumps through them. Do they rattle against the wall or shake as the water goes through them? If they do, stabilization is necessary.

If this doesn't seem like a major deal, imagine the damage that can happen to your pipes if you let them continue to rattle and scrape against the wall. While this won't cause serious problems right away, the slight friction damage could grow into a larger problem over time.

Spray Foam Can Stabilize The Pipe (And Much More)

Spray foam insulation is one of the most useful ways to stabilize loose pipes. It will adhere them in place, shield them from contact with the wall, and stop them from rattling. Beyond these benefits, it will also insulate the pipe and keep it safe from expanding and contrasting with extreme temperature changes.

The proper application of spray foam insulation is something that most home owners should be able to do on their own. If you're uncomfortable operating a foam sprayer or simply want some help, most repair service companies should be able to help.

Applying Spray Foam Insulation

If you want to do this repair on your own, start by purchasing some spray foam insulation and an applicator spraying machine. These can be found in most hardware stores. Tell the store employees why you need the foam and they can help you choose the best type available.

Now, attach your sprayer to your bucket of foam insulation and spray it around the pipe. Make sure to focus the foam on the areas near the wall, where the pipe will rattle. Test the pipe for give as you spray, pushing it slightly back and forth, to make sure it is getting fully cushioned.

After you've covered the pipe, let the foam insulation dry for a few hours and flush your toilet. If the pipe still rattles a little, apply more foam insulation. Once the rattling has stopped, your job is finished.
