Review on Moen 97479 Monticello Widespread Bathroom Sink Faucet Stem Extension Kit - Enhanced for SEO by Johnnie Bowlan

Like many others, my Moen cartridge nut was frozen in the faucet body and the head came off when I tried to remove the nut because it's plastic. I even bought a matching nut removal tool, part number 179120. So I took a small wood chisel and carefully snapped off the damaged plastic nut. I also pry up and pry the plastic nut off the internal threads with a small chisel. I tried my best not to damage the internal threads of the faucet. After removing the protective nut, I used a copper wire brush to clean the threads as best I could. OPTION #1: I have a Kingsley Moen bathroom faucet and couldn't find the part number for the replacement nut. So I took a chance and bought this Moen expansion. Luckily a plastic nut fits. There are two plastic nuts in this pack, I used the longer one. Then I tightened the extension nut until it held the cartridge in place and my problem was solved. OPTION #2: If your threads are too corrupt, try this option. I took a smaller threaded plastic insert and cut it down the middle where I actually removed a small piece of plastic nut so I could screw it over the damaged threads. I then purchased an internal snap ring (size ⅞) and used thin needle nose pliers to place the snap ring over the plastic threaded nut. As a result, I had to trim the blue plastic insert so that it didn't touch the head of the snap ring. The problem is solved. ANOTHER IDEA: Instead of using the plastic nuts in this pack, you could try using a ¾ inch copper pipe, put it over the valve and secure it with the internal snap ring. I read many other reviews. with similar horror stories about the nut freezing when they finally pick off the nut's head. Some even had to buy a new faucet. If you take your time and be careful not to damage the metal threads, Option 1 can fix and save your expensive faucet. If the threads are damaged try option 2. I believe mine was frozen due to my hard water condition. Somehow some water had to get in over time and the minerals froze the nut. If I had to do it all over again, I'd probably pour vinegar down the faucet first to help break down the hard water buildup. After letting the vinegar sit, I would attempt to remove the plastic nut. I've read that vinegar can break down limescale. I applied PB Blaster spray to a plastic nut hoping it would destroy the source of the problem, but it was a waste of time and didn't help at all. Don't waste your time with PB Blaster or WD-40 in my opinion as they don't dissolve hard water minerals. I hope this review helps others to solve the same problem with nuts. Much luck.
