Toilet tanks sweat due to the difference between the temperature of the water in the toilet and the outside air. The water in the tank is cold, which makes the surface of the tank also cold. When warm air in a room comes into contact with a cold tank, water droplets, also known as condensation, form on the surface. This is a common problem for homeowners during the spring and summer months when the weather is warm. Even if you don't care about the moisture in the tank, water from a perspiring tank will drip directly onto the floor, causing damage to the floor and subfloor over time. There are several ways you can keep the toilet from sweating.
Step 1. Cover the toilet tank
Buy a tank cover or take a piece of cloth and wrap it around the toilet bowl. Usually, this is done using terry cloth or the material from which the towels are made. The fabric will absorb condensation that has accumulated on the outer walls of the tank.
Step 2. Create ventilation in the air around the toilet
Place a fan near the toilet or turn on a fan in the bathroom to dry out condensation that forms on the toilet and to reduce the amount of moisture in the air. Moving air will better dry condensation on the toilet if there is adequate space between the toilet and the wall. If there is no room for air to circulate around and behind the toilet, it will not be able to evaporate condensation. You can also resort to a dehumidifier. However, do not forget that the bathroom has a very humid environment, so the device will have to be used constantly.
Step 3. Reduce the temperature in the bathroom
Turn on the air conditioner to reduce the temperature of the air around the toilet, so that it is closer to the temperature of the water inside the tank. This will reduce the amount of condensation that forms due to the contact of the cold tank with warm air.
Step 4. Install a mixing valve on the toilet to increase the temperature of the water that enters the tank
This valve is attached to a cold water pipe that goes to the toilet and connects it to hot water. This will increase the temperature of the water entering the tank, which will reduce the difference between the temperature of the tank and the outside air, thereby reducing condensation on the tank. The hot water supply can be shut off when heating is not needed.
Step 5. Purchase a mixing tank
Its principle of operation is similar to that of a mixing valve. Water enters the tank at an equivalent temperature in relation to the outside air, where it is first heated in a separate tank.
