How do keep a toliet tank from condensation? It is always wet . It was dripped enough to ruin the flooring?

Answer 1

I remember seeing this problem on Ask This Old House. They had 3 ways to correct this problem. A retrofit insulation kit for the inside of the tank, A new insulated toilet, or Installing a mixing valve on the toilet intake to raise the water temp in the tank.
The segment was called "No Sweat Toilets" they have a synopsis of the story on their web site.

Answer 2

I recently bought and installed two new toilets. They are made by Niagara and I bought them at home depot. They are about $100 each. They are low volume, 1.4 gallons and they store the flush water in a "trough" located in the top of the tank. There is no water in contact with the tank when not being flushed. When flushed the "trough" is tipped by the flush handle and the water cascades into the tank and out through the flush hole. This give the water more velocity for a good flush. I highly recommend this toilet. The mechanism is simple, they flush great and don't sweat.

Answer 3

It has to do with the temperature of the water in winter usually, at least for us here. The water is colder when it goes through the water pipes in the ground(as it goes through the city and so forth). In the summer it stops because the ground isn't cold or frozen.

You can get a thing to gather the water, which goes on the bottom of the tank(I think I saw it at Walmart). Also you can get a liner for the inside of your tank that's supposed to help. We just have a paint tray on the floor behind our tank to catch the dripping, and it works fine. No pools of water.

Best of luck.

Answer 4

It sounds like you may have a leaky flapper valve. If it's leaking it could allow some water to continuously run through the tank, thereby keeping it cold all the time. You can check this by shutting off the water supply to the toilet. Then see if the tank water level goes down.

Answer 5

I think I remember reading some where about a liner for the bowl, to reduce condensation. It is the cold water against to warmer, humid air outside the bowl.

Answer 6

The only way to stop the condensation is to buy a lined toilet tank, or you can buy a liner kit for your existing tank. The liner kit is very messy to install and not as good as a new lined tank.

Answer 7

Best is to put a mixing valve in to add warm water to the cold eliminating the ice cold water that causes condensation.

Answer 8

We had a similar problem. We had to rip up the bathroom from floors to walls and replace them with waterproof materials. I don't know that there's anything that can prevent this from actually happening, though.

Answer 9

Put a dehumidifier in the bathroom.

Answer 10

you need to vent the bathroom, the humidity is way too high
