Thank you for the video. I just replaced both of cartridges with the Moen 1248 replacement. I pulled the first cartridge using needle nose but couldn't get out the second one with that method. Since I was replacing the entire cartridge, I screwed in a 4" wood screw in place of the original screw and with a block to protect the tub, pulled the cartridge out with a crowbar. This method needed very little force to get it out.
After 19 years my tub spout was dripping so I got 2 of the 1248 cartridges and the Moen cartridge retainer removal tool which was required because my valves were seated very deeply. Pulling the old cartridges was impossible with needle nose or vise grips so I used a long machine screw in the screw hole and then used leverage on that to extract the first. The second one, the cold water, was in so hard that even that didn't work (the machine screw pulled out) so I went for a cabinet screw with an aggressive thread and oversized head. Again using a wood block for a pivot I was able to lever it out with vise grips. Both cartridges and their copper mating surfaces had blue scale deposits, likely from the copper reacting with our local water, that had to be removed. A "tooth paste" of white vinegar and baking soda applied with a used toothbrush cleaned that up.
Thank you for the video. I just completed the job. To pull the cartridge, I used the Danco 86712 core puller. I unscrewed the outer collar from the puller and put the puller inside the tube. I screwed the puller to the cartridge handle. I then turned the water on to give me an extra 40 lbs of thrust. I then pulled on the cartridge and it popped out. I was able to turn the water off quickly to not make too big of a mess.
One thing not mentioned is that the cartridges have an alignment tab that mates with a cutout in the valve seat. It aligns the cartridge to insure the outlet side of the cartridge is next to the spout feed. The tab is directly opposite what looks like a V on the top of the cartridge. The V in my case was on the side of the boy furthest from the spout. I suggest you take a picture or mark the location (blue tape and a marker in my case) BEFORE you remove the old cartridges. If the alignment tab isn't positioned correctly, the cartridge won't seat completely and you will get low or no flow when you turn the water on and a possible leak from the valve body when the water is on (but not off). Aligning the tabs when the value seat is recessed a couple of inches and you don't have Xray vision was a bear in my case.
Scott, thank-you. Your video was the only one I could find on this faucet. Your experience and the discussion below was extremely helpful during my own misadventure. I added a video because I ran into even more problems (stripped screw heads, stripped or cross threads while removing the retaining nut, poorly made replacement parts, etc.) and came up with some convoluted solutions.
Scott - Yes thank you for this video it was VERY helpful as I am working on this now. I am in a holding pattern until I get the parts I ordered. For your new viewers who may see this comment.... One thing I learned that work for me when removing the Stem extender and cartridge. I remove the Cartridge nut first, then I was able to pull the cartridge and stem all together, I also drilled a hole in the stem extender then put a screw driver thru it to use as leverage when pulling up the stem tubing, since I am replacing it.
Thank you so much for this video. I had no idea where to start and that there was a retainer ring that I needed to unscrew before removing the cartridge. Employees at Lowes of Home Depot were totally unhelpful.
Oh man this video was great. Made me feel better about my last attempt. I ordered the wrong size so I attempted to repair the old cart. I got new o-rings and pulled the inner part out but broke the little cheesy tabs. Ended up stuffing the old one back in so’s to stop the leak. Now my wife has been only able to use the hot. I’ve got the Moen 1248 carts sitting in my mailbox. Hopefully they fit! Fingers crossed. Thanks for the video!
This video is exactly what I wanted, cartridge was so stubborn to come out. I thought pulling it up may break the faucet valve, and there might be other way around. Now I know, I will just pull it up...;) thank you....
I just did this just a minute ago and learned the hard way that the stem should not be unscrewed when pulling the cartridge out. Makes taking it off easier. Just discard both after.
Thanks! I’m replacing Roman bathtub Moen fixtures with Pfister ones and this showed me how to disassemble the old ones. Also how much force may be required to pull out the cartridges 😜
Hello sir! Great video.. if you can recall, how big is the screw down inside of stem assembly? I think it would be the second screw you removed I fear I may have lost it during remodel. Any info would be great. Thanks
Wonderful video this faucet has a long to replace. Do you know the model of the faucet itself?? For a leaking faucet do all these parts need to be replaced or just the Danco 4191b
Any idea how to remove the escutcheon adjuster? That part is stuck. In hour vid it looks like if comes out all in one piece with the chrome skirt? Mine is 2 separate pieces
Hey Scott! Thanks for the video. From 2:15-2:32 in the video you are using the needle nose to take out the plastic piece however I tried and it is not coming out for me, it is jammed in there. Any suggestions or alternate ways to take it out?
I got to remove other parts. but the retaining nut is not coming out. I got a needle nose plier, smallest i could find, and tried. its stuck badly. and the plier is not able to get a good grip.. any suggestions?
Moen has a Cartridge Retainer Removal Tool. It's just a cylinder that is notched at one end to match the notches on the retainer nut. I ordered mine from Home Depot. $4.23
Changing it that time I was trying to fix black particles that I thought coming from disintegrating brings. Turned out to be bad rubber on a flexible hose with shark bites at my water heater. I just changed one of the cartridges for a second time 2 months ago. It would shut off. Just kept dripping
The parts have a lifetime warranty from Moen. It's really easy to make a warranty claim. They sent me everything I needed (except silicone lube) for free.
i had the same problem. now i need to brake the black nut. Asked them resend the nut and this time they mailed me the white kit. hope that is not that tight
