Review on 🔧 Moen 96988 Cartridge Repair Kit: Enhancing Performance and Longevity by Dan Weeman

The shower head started dripping many months after the unit was installed as part of a renovation project, but the new shower has never been used. The cartridge has deteriorated without being used. How is that possible? Who knows ? It's plumbing! Replacing O-rings is easy; The tricky part is getting the assembled stem into the new plastic case. New o-rings tend to get pinched between the stem body and the inside of the plastic body at the holes. This blocks the movement of the stem body. Using force can destroy the o-ring or render the cartridge unusable, so persuasion is best. It was not easy and very exhausting. So, either your time or money to replace the cartridge. If you can initially easily remove the old cartridge from the valve, it will be much easier to simply replace the cartridge. Generally, if you are struggling at this stage, you are in for serious deterioration. While I was able to repair the cartridge and stop the leak, I would avoid this manufacturer in the future if possible. Tip: Use the grease from the kit, nothing heavier.
