How To Deal With Toilet Tank Condensation To Prevent Water Damage To Your Floor

If your toilet tank often feels wet and you see water dripping onto the floor, the problem might be condensation. Whether the water is coming from a leak in the tank or condensation, you'll want to make repairs as soon as you can so the floor behind the toilet isn't damaged by the water. Here's why condensation forms on a toilet and how to fix the problem.

Condensation Forms Due To Temperature Changes

When the water that fills the toilet after you flush is much colder than the air in the bathroom, then condensation can occur. This happens in the same way that a glass of iced tea starts sweating outdoors on a hot summer day. The condensation is usually worse right after you flush since water is the coldest then. The water warms up some the longer it sits in the tank. This is one way to tell the dripping water is from condensation because if it were from a leak, the water would be dripping continuously. Also, you can actually feel and see water dripping down the sides of the tank as opposed to just seeing it drip from one place as you would with a leak.

Simple Ways To Manage Condensation

If you want to put off calling a plumber, you can try a few simple tricks to manage the condensation although they won't stop it altogether. One thing that might help is to control the climate in the room with air conditioning or a dehumidifier if possible. You can also consider covering the tank with a thick covering made of rug-like material. You can buy them with elastic around the top and bottom for a snug fit.

This helps to insulate the tank and soak up condensation. The big drawback is the way the cover affects the appearance of your toilet, plus the material may start to smell like mildew if it isn't changed often. Another option is to protect the floor with a drip pan or towel that you change when needed. This will prevent water damage to the floor, but it is not a permanent solution, and it makes your bathroom unsightly. If you want a permanent fix, you can call a plumber for help.

Permanent Solutions For Toilet Tank Condensation

The first thing your plumber may do is ensure the toilet flushing mechanism is working properly so the toilet doesn't run more than usual, which would keep the water in the tank colder. If necessary, repairs are made to stop the toilet from running. Your plumber may discuss the option of replacing the toilet or just the tank. A more modern toilet that holds less water may have less condensation, plus newer toilets often have insulation inside the tank to combat the problem.

Another solution is to add insulation inside of your current tank, so it is out of sight. Your plumber may decide to work on the plumbing lines rather than the toilet since this is often the best way to stop toilet condensation. The method involves cutting the pipe and inserting a mixing valve into the line that allows a little hot water to mix with the cold water as it fills the tank. This keeps the water from being so cold that condensation forms.
