leaking around shower valve cartridge
Five years ago I replaced the Moen 1200 single-faucet cartridge in my
shower. Now it drips from the knob. It seems to be leaking around the cartridge. I found the plastic adapter and, after tapping the pipe, got the cartridge to turn. Drawing it out will be another matter. I don't recall that the one I replaced was hard to pull out, once I turned it. How should I get this one out? Is there an anti-corrosive/sealer/lube I should use when installing a cartridge? Should I not remove it until I have a new cartridge on hand? |

Just fit it with the right screw to fit the cartridge and give it a couple of smart whacks. I have found it is usually hard water residue that has built up around the cartridge that holds it in place. And yes, have the replacement in hand before pulling the old one. Charlie |

Charlie ....otherwise you won't be able to turn the house water back on until you install the replacement, unless you happen to have separate shutoff valves for the shower, and/or you cut off and cap the pipes feeding the shower. nate |

I think the cartridge is fine except possibly the external o-rings. The one I replaced lasted 20 years, until it became hard to shut off completely. This one works beautifully and slides easily. If this one has begun to drip (a pint an hour) in five years, perhaps it's because I didn't think about removing possible corrosion from the fitting before inserting the new cartridge. I don't think Moen mentions that step, or using plumber's grease. Perhaps the one I replaced was also hard to turn, and I've forgotten. Before I went to bed, I remembered that it had always been necessary to use pliers to pull a cartridge out by the stem. |

I stuck a #0 Phillips through the stem and couldn't budge it. I laid a big screwdriver on the rim of the fitting and pried against the Phillips. Easy! Yep, corrosion in the fitting. I wound up a Scotch Pad, stuck it in the hole, and turned. Then I dried and greased it. The o-rings look good but, naturally, the metal has corrosion on the surface. I'll buy a cartridg to keep on hand. With plumbers' grease, I hope the fitting lasts and lasts. Thanks, Charlie and Nate, for your advice. I was scared! |
