During the summer months, we welcome the warmer weather, with the downside of elevated humidity. When warm, humid air hits a cold toilet tank, condensation forms resulting in damage to bathroom floors, and left unchecked, the sub-flooring.
Fortunately, this problem can be addressed in a number of ways, from simple to complex.
Reduce the humidity in your bathroom by changing your routine from winter’s dry air to summer. Here are some suggestions:
Warm up the water in the tank by installing an anti-sweat valve (see links for more information).
Purchase a tank insulating kit that will warm up the tank. This solution may involve emptying the tank to install the insulation but might be worth it.
Check the flapper valve. If your flapper valve at the bottom of the tank is leaking, the toilet will regularly take on a lot of fresh, cold water to replace the water that leaked out. If you stop the leak, the water in the tank can reach room temperature.
As always, simple everyday maintenance helps tenants to have a welcoming home and pleasant environment. By taking small steps, you can reduce the toilet condensation and prevent floor damage, keeping your bathroom clean and healthy.
