Hi, We are having a problem with a gas hot water tank (40 gal). Back in 2002 (brand new house 2001) we found that the pressure relief value was blowing water after we took a shower and empting gallons of water on the cellar floor. We had a plumber install a expansion tank and this resolved the problem. Now the cellar floor has gallons of water on it again. I found the pressure value was blowing water again after showers. What else could be causing this problem?
Also ! I noticed that there is a air pressure value (looks like a bike tire air value) on the bottom of the tank. What is this for? Is there suppose to be pressure in the tank at all times or are you suppose to bleed it off? What is the pressure suppose to be? What kind of gauge do you read it with? (bike or car tire gauge)?
