  1. Moen tub shower valve valve 1222 still drips/runs

    I have a Moen posi-temp single handled tub-shower faucet. It takes the 1222 faucet cartridge. I first rebuilt the cartridge and it kept running a slow but steady stream of water. I bought a brand new replacement cartridge... and STILL it runs!!! Driving me crazy. I've got $50.00 into this now and no improvement.
    Did I do something wrong? Is there a trick to the install, like a combination of twists adjustments I'm not aware of? The instruction sheet is worthless and in micro-print. ...
