Questions and answers
I replaced the cartridge, and the new one has a fine drip in the off position. I purchased another one and it does the exact same thing. I also replaced the check valves and no change. I have not installed the hot or off stops, so they can't be out of adjustment. Am I missing something? I followed your instructions and have quite a bit of mechanical ability. Please advise. Thanks!
A fine drip in the off position after replacing the cartridge in a Sigma Tempress II could be caused by misaligned or improperly greased O-rings, a misaligned cartridge, or worn non-return valves or their rubber gaskets. It may also be due to debris lodged in the cartridge inlet or valve body.
