 ceramic cartridges seizing
Author: johntaylor (Non-US)

A friend of mine has 10 faucets ( installed over 20 years ago) throughout the house with quarter turn ceramic cartridges and all seized , but not dripping

After putting cartridge in CLR for an hour ( and boiling in microwave) it was still seized, so scale was not the problem. After removing ring clip at top of stem and disassembling cartridge , the two O rings on the stem had completely deteriorated and dried up into gunk that caused the seizing. Two new O rings with some vaseline did the trick. While you're at it . does'nt hurt to use CLR to remove scale from all other parts. Quality of the cartridges that were over 20 years old far superior to the ones I bought at local hardware store.

1. I would not buy replacements at a "local hardware store".
2. I would NEVER spend the time required to disassemble, clean, and/or repair a ceramic stem. And then reuse it.

Ceramic cartridges, were never designed to be repaired. Ceramic Cartridges were designed to last longer and perform better then brass stems. They are generally, more expensive, but worth it. What brand of faucet, do you have?

Best Wishes
