I tried to save some money and buy hiring a cheap contractor to do the electrical and plumbing on a bathroom renovation. After finishing the tile myself I tried the shower and quickly discovered and dripping in the access panel. After several attempts to fix it unsuccessfully he finally assured me that it was fixed. When I did the test just a bit ago the cold supply line was Dripping about once every 45 seconds to a minute. The pipe is wet from condensation but the valve seems to be more let them condensation would explain away. It drips about once every 45 to 60 Seconds. It's very cold (13 degrees) so the cold water is very cold. House is roughly 70 degrees. But that sort of drip be explained by condensation alone? Or is it a leak? When I dry off the valve with a paper towel it becomes wet in under a minute. Then drips pretty steadily about once a minute. The 8 month old valve itself is Rusted but the contractor claims that that is from a leak that he fixed in one of three previous visits.
