Moen Roman Tub Faucet Dripping Repair

In this video I show you what I did to fix a Moen "Roman Tub" dual handle faucet (Chateu Two-Handle Garden Tub Faucet) that was dripping.

This model, 4902, uses cartridges, so the video shows the process of accessing and pulling the old cartridges and replacing with new cartridges.  The cartridges are down pretty far in the valve body, so a special tool is required to get the cartridge nut out.  The cartridges I needed were the older Moen 14891, but these are similar to the common Moen 1224 cartridge.

The cartridge nut removal tool, Moen 14272 works with 1224, 1234, and 1248, as well as my old 14891, and probably more.  I did not buy the tool.  Instead, I made a tool out of 3/4 copper pipe to remove the nut.

The video includes some of my initial research, and how I approached the problem, looking at the instructions on the Moen site, as well as what people were saying on Amazon about the nut removal tool.

This might not be the right way, the perfect way, the way you'd do it, the way a professional would do it, but it's the way I did it, and it happens to have solved the problem.  Enjoy!
