So, I'm obviously doing something wrong, but I'm not sure what. I have a delta two-handle fixture in my bathtub and it was steadily dripping from the faucet, so I thought I could fix it myself. I purchased a 5-pack of 3S-2H/C stems, seats, and springs from Home Depot because it made the most economic sense, and figured since I had the 5 pack, that I should replace both sides. The cold side has been doing fine since, however, the hot side continues to develop a leak. I'll replace the spring, seat valve (may not be the correct term) and stem on the hot side. When I turn the main water back on, there's no leak. However, if I turn the hot on and back off, it develops a leak, and this happens:
Like I said, on the cold side, everything is fine and I followed the exact same process on both sides. Can someone tell me what I've done wrong? Any help is appreciated!
