Bought the house in 2007, its older, built in 1959 I believe. Had to replace the hot water heater in March 2008. Has worked great since then, until a few days ago there was a good amount of standing water on the basement floor under the water heater from a constantly dripping T&P valve (I know, I need to connect a drainage pipe to outside). I replaced it and still had the same problem. That was the limit of my "vast" plumbing knowledge, so a plumber came and checked pressure (72 psi) and could find nothing else wrong so he replaced T&P valve again. Next morning, buckets full of water again. I turned off the water shutoff valve to the water heater itself, but it still leaked even with the water supply turned off (baffled!), so I finally had to shutoff the main water into the house. Plumber came back this morning (on Thanksgiving, great guy!) and suggested a thermal expansion tank as the only other option he could think of. Any suggestions? Any ideas why this problem would just now arise after a year of an old water heater and 18 months of the new one with no issues? What kind of cost should I expect for the expansion tank and labor? Thanks so much. Y'all are great.
