Here’s how to fix condensation on a toilet tank before the dripping water rots out your bathroom floor. If you’ve noticed what happens to an iced drink on a humid summer day, you’ll have an idea why your toilet is sweaty. When warm, damp air hits a cold surface, condensation.

Shell Busey shows you how to stop condensation from forming on your toilet tank. For more videos or to ask Shell a question on any home improvement topic, go. Toilet tanks sweat—that is, build condensation on their outer surface—due to the difference between the cool water in the tank and the warm, humid air outside.

How to Stop Toilet Tank Sweating. Even if the wetness does not bother you, the. After that, there is a good chance that your home’s temperature is going to be much higher.

This is going to create condensation and that will ultimately cause the toilet to sweat bullets. The warmer air inside of your home will make contact with the toilet’s tank and that will make the tank sweat. During humid weather, the tank temperature can be low enough to cause the moisture in the air to condense on the tank surface. Installing it as simple as emptying and drying your toilet tank , cutting it down to the height of the tank with scissors, peeling the protective sheet off to expose the adhesive backing, and applying to the inside of the tank.

What Causes a Sweating Toilet. A toilet tank cools down when it fills with cold water.

Summer means heat and humidity in many parts of the country, and that may mean condensation on your toilet tank. Warm, humid air comes into contact with the cool porcelain, and the resulting condensation drips down the tank and onto floors. The water that collects on your toilet tank is condensation – moisture that’s been pulled out of air in your bathroom. As it turns out, your toilet is a natural dehumidifier. The moisture forms on the surface of the tank because the tank water is colder than the surrounding air temperature.

But if a toilet is leaky or running, in warm humid weather you may notice that the toilet tank is wet with condensation even when the toilet has not been flushed for several hours or more. Toilet tank condensation , if chronic and significant, can lead to bathroom floor tile damage, subfloor rot, and even attack by wood destroying insects or mold. When this condensation or sweat drips off that tank of your toilet , it will make your bathroom floor damp for several days, damage it, and rot out your subfloor and framing.

Toilet Tank Drip Tray Toilet tank drip tray catches condensation from the toilet tank. Eliminates water from dripping on floor and prevents damage. Easy to remove and clean. There used to be these tank liners sold that you would install on the inside of the tank to insulate it.

It keeps the outside of the tank from getting as cold to reduce or eliminate condensation. I did however find toilet tanks that come with insulation already installed. Instea condensation forms on these surfaces as warm, humid air makes contact with the pipes and the toilet tank, which are both cooler because they’re filled with cold water—just as droplets. This will happen on a glass filled with a cold drink. There are two general solutions to stop tank condensation.

Condensation under toilet cisterns can cause unseen problems.

The warm air in the bathroom hits the underside of the toilet cistern and cold water pipes and condenses immediately (for more about this see our project on condensation ). DIY Doctor has devised a method of minimising condensation on toilet cisterns and cold water pipes. The second method involves installing an antisweat valve in the water-supply line leading to the toilet. The valve adds a little hot water to the line, which raises the water temperature in the toilet enough to warm up the tank and bowl.

A simple solution is to add a tank cover to the outside of the tank. Another method is to install an insulating liner inside the tank. Kits are available from the plumbing supply stores.

Follow manufacturer’s installation instructions. Another thing to consider after you deal with the filling problem is something called toilet timing. Toilet condensation seems a universal summertime nuisance whether you live in a grand house or a little cottage. The problem occurs when warm, humid air condenses on the cool porcelain surfaces. This causes water vapor in the air to turn back to liquid water upon contact with the cool ceramic surface.

The first is to increase the water temperature in the cold line. The floors get wet and worse the water can seep underneath flooring and damage sub-floor material. Install a tempering valve in water line feeding toilet. Tempering valve will mix hot and cold water together so warm water fills toilet tank which will stop condensation.

Any ideas on how I can stop constant heavy condensation on a toilet cistern - so much that the floor under the cistern is constantly wet. The toilet unit is a bog standard (pardon the pun) close coupled toilet , water supply off the rising main. Fairly good ventilation as the door is rarely close radiator on most of the time in the winter months.
