Moen 1248B Two Handle Replacement Cartridge

Saved us from buying a whole new faucet. Moen offered to send replacement due to warranty but Amazon product was expected much more quickly. Was an easy diy replacement (with a couple of YouTube videos to get the the pieces out). Note, it is directional and must be installed the right direction. Read more

I learned the hard way that the tub cartridges are available off the shelf at the big box stores. The tubs take a slightly larger (by about 2mm) cartridge and these are what I needed. Perfect fit and stopped the leak. However, I do recommend buying the cartridge tools. My old cartridge broke on removal and getting the pieces out was a real B. Read more

The product worked well and was an exact fit. Removing the old cartridge can be challenging. The faucet on our jet tub had the extensions as well. The spanner style tool is needed to remove the retaining ring. But I had to fashion a puller to get the cartridge out. Read more

I've been a plumber for all of my adult life (over two decades now) and I can't say that I know of another cartridge that has the longevity of the Moen 1248B. We've had this cartridge in our Moen Monticello Roman tub valve now for over 15 years without a single drip. And that's in southern Arizona where the water coming out of our well is practically liquid rock. That's to good news though. The bad news is that these cartridges are a real bear to change out, and I mean a real bear. Compounding that problem is the fact that you have to change them so infrequently that you'll forget the painful lessons you learned by the time you have to change them again. First of all don't even think about trying to change the cartridge without the special Moen cartridge retaining ring removal tool made for the 1248B. It's not really expensive but unfortunately you'll have to do it so infrequently you'll probably have misplace or forgotten what the tool was for by the time you have to do it again. Just plan on buying one every decade or two when you purchase your cartridge. Second, when you do get all the parts of the this valve disassembled and the cartridge retaining rings removed from the valve body, you'll have to really, and I mean really, pull hard to get the cartridge out of the valve body. If you have hard water or heavy minerals, then you have my condolences. I replace these cartridges so infrequently for my customers that I've never looked for a cartridge removal tool. There may be one but I don't know. In any case gook luck with pulling them out. Once you do get the incredible little cartridges removed make sure you clean out any loose hard water or mineral build up in the valve body by flushing the valve for a few seconds. If the build up is really bad you might want to use a light duty copper fitting brush to trying and clean up the inside of the valve a bit. Make sure you lubricate the cartridge before you try and insert it back down into the valve body. Silicon or faucet grease will work. Now the hard part. There is a tricky little notch down in the bottom of the valve which the cartridge needs to seated into. The problem is this notch can't be seen once you've reinserted the new cartridge. So it might be helpful to mark the top of the valve body with an indelible marker to show yourself where the notch is located so you have a better idea of your target when you insert to cartridge. There are at least two ways for you to know you missed the notch. First, if one of your cartridges seems a bit higher than the other then something is wrong. The notch is about 1/8-1/4" deep so you can see the difference if one of the cartridges doesn't seat correctly. The other way is if once you turn the water back on and one of the side of the valve doesn't have full volume. (the cartridge must be seated properly to get full flow through the valve.) In any case don't put all the pieces of the valve back together before you test to see if you've got the cartridges seated correctly. (but do make sure you've screwed the cartridge retaining ring all the way down so the water pressure can't push the cartridge out, however unlikely) Once you've tested the valve and everything is okay then put all the other trim pieces back on and you should be good to go for another 10 years or more. Just to be clear. This cartridge is not for my 15 year old Monticello valves. They are still look elegant and are working great. I have a customer who has a slight drip on their tub and I purchased these cartridges for them. Personally, if I had to do it all over again, I would still use Moen Monticello for my Roman tub, lavs, and shower in or master bathroom. I just don't look forward to the day I have to finally change the cartridges. Read more

This was exactly what I needed. Supposedly Moen have a lifetime guarantee on these parts so you may be able to get them for free but rather than hassle with that I bought it here. My hot water always had a very slow drip. Then one day the valve gave out completely so I could not turn the hot water off. I turned the water off and was eventually able to close the valve with a players. I replaced this piece which was a bit challenging but everything has worked since then. One thing to note is there is a tool sold n Amazon to screw out on piece. The tool was totally messed up but I was able to screw tue piece out by putting my needle nose in and then opening it to catch tue sides while turning it out. I also found a YouTube video on replacing this exact piece, but that was a while ago so I don’t have the link now. Read more
