MOTHER EARTH NEWS readers receive guidance on condensation in a toilet tank, including tests to make on toilet parts and room temperature changes.
I have a problem with condensation from my toilet tank. We want to put an oak floor in the bathroom, but we're afraid the toilet tank condensation will ruin it in no time. Meanwhile, we keep a long pan on the floor to catch the drippings. Any suggestions?
First, make certain the toilet tank condensation isn't coming from a hairline crack in the tank — or from a damaged ballcock valve or seat, which could spray water onto the lid and down the outside of the tank.
If you've determined that the tank is indeed sweating, try lowering the temperature of the bathroom and the surrounding area and reducing the humidity of the room with a dehumidifier or a ventilating fan. In addition, you could install a plastic tank liner to insulate the tank walls from the cold water.
