Moen Roman Tub Faucet Dripping Repair 

Excellent advice! Using a long deck screw to remove the stuck cartridge worked like a champ. Just made sure the lifting force from the claw hammer kept the screw perfectly vertical throughout the lift. I can’t thank you enough. Spent hours watching youtube videos of various tools that were incompatible with the Moen 1248 cartridge and had about given up. Your solution was the best of any. Awesome!

Brilliant! We have the same fixture, circa 1993, and the hot side cartridge finally gave out and began to drip. What a blessing your video has been for me to replace it. Thank you!

God bless you!!! I was about to give up (which I never do) and made all kinds of homemade tools, looked at RU-vid’s until I was blue in the face, but wasn’t sure what brand faucet it was. And then … I decided to use the Google Lens and it instantly told me what brand and model 😁 Then I found your video. You Da Man!!! I’m going to do it tonight after work. I also ordered a WiFi valve to turn off the water. My wife doesn’t do anything fast so it’s just easier this way … LOL. Thanks again!!!

my knob completely fell out, and your reconstruction part at the end of this video helped me put it back together. thanks!

You saved my day ! I couldn’t find or afford a plumber … thank you for sharing your solutions !

Yeah I got one just like it tysm for posting, unraveled the mystery for me! parts were clean and serviceable, just needed new O-ring. Valves lifted out easily with gentle pressure on the stem extensions, slipped plier under the top nut and gently levered, popped right up. My escutcheons so frozen to pipe after 24 years they won't come off, I saw another post where some desperado sawed em off with a dremel cutter, lol. Nice post for what looks like an easy job but isn't, tyvm!

This is the exact video I was looking for. I will give it a shot tomorrow.

Measuring the depth that the old cartridges sit down in the valve body BEFORE removing them is a key step. There is basically no way to otherwise be sure that the tab on the cartridge is aligned and seated in the matching notch on the valve body. On the 1248 cartridge the difference in height between aligned and fully seated verses misaligned and not seated is about 2.4mm. I recommend using a digital caliper's depth gauge for all the measurements but a manual one or just a witness mark on a small flathead screwdriver's shaft may work, depending on how good your eyesight is. If you don't get the correct depth all you can do is remove and reinstall slightly rotated until it seats. Trying to rotate the cartridge body while in the valve body is almost impossible even if you can get it to turn because the fit it so tight that you can't rotate it accurately - just getting it to move insures once it does that it will move more than you want. If you find blue deposits on the inside of the valve body, fold a half sheet of paper towel and then roll it up from the sides so one end is the doubled up towel. Work the towel down into the valve body using a twisting motion. Once the towel is fully down, saturate the towel with white vinegar and let is sit for several hours, then repeat the bottle brush cleaning. White vinegar one a paper towel will also remove the blue stain that you might find in the tub if the dripping has been going on long enough. Allow several hours for the project as all the steps can take time - if you're lucky it will all go quick and easy but don't bet on it. A water shutoff can be a challenge to domestic tranquility.

Thanks for making the video and sharing your experience. Interestingly, you mention "getting up the courage" to do this DIY fix; it took me a good month to have the courage to work on mine. All turned out well, except I still got an extremely slow drip, which drives me crazy! I spoke with Moen, and they are sending another pair of cartridges. I get to do this all over again once they arrive. This time, I will measure the depth per your recommendation and hopefully get these cartridges seated correctly.

Awesome!!!! With your video I found the solution to my own. THANK YOU!!!!

Your good at explaining this. Nice work!

Thank you for this video Tutorial! I was able to repair mine today !

Thanks for making this video. Hopefully my cartridge replacement goes this well.

Thanks for sharing this! This made the difference between a $20 project myself or what Im sure would have been hundreds on a plumber

I saw that you used the 1248 cartridges to replace the 14891 cartridges, but in your description you mentioned that the 14891 is similar to the 1224. Did the 1248 work?

Just a tip for those who want to use long nose plyers. The standard size is 6" long, and that doesn't work very well. The middle part is too wide. The next smaller size is 5" long and the middle part is more narrow. I have both and my 5" is spring loaded open so you just squeeze and release inside the faucet tube. It works perfectly.

Very HELPFUL....Nice detail

Great video, I am having to remove the same, however the cold one has a rusted out screw that hold that extender to the cartridge. Did you have any such issues or did both your screws come out easily?

Great video. My same problem. I hope to try it soon.

Thank you! You saved me! Exactly my problem

Very detailed video. Thanks!

Thanks for the detailed video, I have the same exact tub/faucet setup on my 1999 home. I dont have a certificate with fancy gold stamp detailing the Lifetime warranty. What proof did Moen require in order to get their cartridges shipped out to you?

the deck screw made the difference ,thanks

My thing is, I can’t find remodeled handles to fit the old Moen Roman tub faucets to save my life. There’s nothing wrong with my faucet except these ugly ass clear plastic handles. The universal ones won’t clear that chrome nut for the extension post…

So helpful, thanks!!

If I have the same as you do but want to replace without breaking the tile which one is compatible? To the same one u have? Thanks!

Thanks for the great video! My Roman tub faucet has the same issue and the top part of cartridge inside the handle looks the same as yours. does this mean my cartridge is also Meon Model 1248B? where to find the cartridge info without pulling it out from the pipe?

During my repair, the white plastics nut that screws down over the cartridge broke when using the pipe tool screwing it back in. What can I do?

I found the 1224 at my local Ace, but did you have the use 1248? My set is the exact same as yours.

Basically I need the exact same ones you have or can I use a different one from moen?

Thanks. Legend

Thanks for this demo. You mentioned that Moen sent you free cartridges because of lifetime warranty? Did they require a purchase receipt to prove you paid for them? In my case, these were installed by the house builder.

Very helpful! Thanks

Thanks!

Genius

Hi, I used the tool made for Moen Shower faucet to pull out the cartridge,I reversed the tool. Watch my video (spanish) on my page
