My shower had a very huge leak problem. After doing some research I found that replacing the washer or the stem would be the best solution. I took out my cold stem and saw that it was completely corroded so I replaced it. I took the stem to the hardware store and a employee help me find the right stem for my shower (I hope). After installing it I noticed that leak has seriously improved, but only if I turn the knob really tight. Now I get a very slow drip and after a few minutes if I wipe the inside spout on the shower with a dry cloth the drip stops completely. What I am doing wrong? :confused:
