If you have a Moen faucet in your kitchen and its dripping from the spout you should try replacing the cartridge.
This is a do it yourself project if you have a few basic hand tools and like to figure things out and fix things around the house. The faucet I need to fix needs the moen replacement cartridge 1225 which can be bought on Amazon at this link, https://amzn.to/3k7IDw1. My faucet is a single lever and its model is Moen Chateau 7430 with chrome finish. I shopped the big box stores like Lowes and found the cartridge is $6 more than the price I found on Amazon, so if you want to save some money and don’t need the part immediately just go to Amazon and buy with this link today, https://amzn.to/3k7IDw1.
