Why Are My Water Lines ‘Sweating’ and Why Is There Water On the Outside Of My Toilet Tank?
Have you ever looked at the water lines running under your sub floor, through your basement and noticed condensation on the water lines? When water enters the house, it is cold from being underground, and when it enters your basement, the basement is warmer. So if you are using are large amount of water the water in those lines never has a chance to warm up.
As For Condensation On The Outside of the Toilet
There is most likely water leaking from the toilet tank into the bowl of the toilet. Again just like the water lines in the basement, the water never has a chance to get warm, since there is alway a flow a water running through it.
You may also be flushing the toilet more often and that would keep the water in the bowl cold.
How To Checking a Toilet for Leaks:
A bigger plumbing issue is water leaking through the tank into the toilet bowl. There should be a shut off valve for the toilet at the floor. To check a toilet for leaks, turn off the toilet water valve and wait an hour. The flapper in the tank acts like a plug and should be water tight. If the water level in the tank runs out or goes down then the flapper is leaking.
One other thing to check is if the water level in the tank is OVER the overflow tube. That means the fill valve is leaking and the extra water is going down the overflow tube. Ideally, the water level in a toilet tank should be about an inch below the overflow tube. You might not hear or see either leak on a regular basis, but a toilet leak needs a toilet repair!
