Review on 💧 Moen 146789 Replacement Part: Restoring Your Faucet's Peak Performance by John Taylor

After 6 years of use, a drip from the tap became annoying, especially when agitated with running water. We have hard water and I have found deposits inside which have mostly been removed with white vinegar. I also used #0000 steel wool in the areas where these o-rings sit to really smooth them out and prevent using anything more abrasive than #0000. The deposits appear to have worn away the old rings, resulting in a final size of 35mm ID and 41mm OD. These new rings have an inner diameter of 34mm and an outer diameter of 41.5mm. They are 3.5mm thick.
