I have two upstairs bathrooms. Each had a leaking cold water shower faucet handle. The water only leaked from the handle when the water was turned on. I bought a replacement kit for each one and decided to just go ahead and replace both the hot and cold handles. The replacement in the shower/tub in the main bathroom went perfectly--problem fixed, no leaks, nice shiney new handles. The shower in the master bedroom bath has been frustrating. I replaced both stems, and both the cold and hot faucet leaked water from the handle. I tried two new stems, and the hot water stem was fine, but the cold still had a leak. I tried putting in the two good stems (from the hot handles) from the old original sets. The hot water was fine, but the cold still leaked. I can't tell you how many times I turned the water main on and off to check differrent stems, but I can't seem to get one (new or old) that doesn't leak on the cold side. The old original faucet handles were Gerber, so I got a Danco Tub and Shower Remodeling Kit for Gerber. The stems are identical to the ones that I took out. One other thing, I didn't replace the valve seat, but that shouldn't matter, should it? Thanks in advance for any advice.
