I just painted my bathroom so I took off the toilet tank to get to the wall. I noticed the tank to bowl seal was in pretty bad shape so I replaced it. When I put it back on the left side on the bottom of the tank has condensation. It produces enough to have a very, very small drip (1/2-3/4 in a day if that). It does not do it anywhere else on the tank. I figured it might be the gasket for the tank bolts so I repleced them no luck. It doesn't look cracked so I am fresh out of ideas. Any help is appreciated.

Good morning Dustin,
If it were condensation you would see moisture all over the front, sides. Back and bottom. The left hand bottom of the tank is where the supply hooks into the tank but the connection I would check first is the retaining nut that secures the ballcock. The next thing I would check is the supply connection itself. When you replaced the tank spud washer I think you might have disturbed the seal on the ballcock connection. Cheers, Tom
