After consulting with Moen re: 2 knob Tub "cartridge" replacement, 12 yrs old, cold water not running, I did what I was told, after receiving the replacement cartridge 1248. (warranty replacement) The existing cartridge is "counter-sunk", ie 3 inches at least below the porcelain top deck of the tub. This installation includes an extension piece. The Cartridge and other "works" are inside an approx1 - 1/2 Brass Valve, which make a simple extraction of the original cartridge nearly impossible. I was instructed by Moen to tighten a long screw into the "old" cartridge leaving enough to connect to to pull the cartridge straight up and out. NOT POSSIBLE. this was described as a less than 1 hour job for the "beginner". I know have water running through to my lower level, cant stop the flow. Damage is catastrophic at this point (yes the water was off). I have now read that if the "cartridge" wont release from the original location, the the Valve must be replaced. I can't imagine how that can be done without destroying my tub. There is no access. Period. What is moen thinking of. I want the damage repaired, along with the "warranted" products.

If the water is off but still coming through, open a tap or two on one of the lower levels. Basically the old stem does come out thru the top of the valve. Hopefully Moen sent you the tool to do this job. The tool is a 3/4"diameter about 4 inches long. Even on one end and two little tabs on the other. Take the handle off stem. Remove the upper retaining nut, usually chrome. Pull out the two plastic upper stem pieces. Insert the 2 tabbed end into the stem area. You will feel the tab drop into the retainer ring. Slowly rotate the retainer ring out Counterclockwise. After the retainer ring is out then put the long screw in the stem and pull it out. Sometimes a little leverage helps here. You will have TWO retainer nuts. The first one is easy just under the handle, the second will require the special insert tool. Please rate this response and good luck, Phil

Leaking shower/tub faucet, looking for replacement cartridge. cartridge is stamped "MOEN with #96909. Tub faucet has pull up knob to divert water to the shower, valve is single handle. I replace it with a "Moen Posi temp cartridge" it corrected the leaking faucet but it would not allow the water to be diverted to the shower head. What cartridge is the correct replacement?

My Danze showerhead runs even when turned off


Try cleaning the inside of the valve with 1500 grit wet sandpaper. and then put a lot of waterproof plumbing grease in there and also on the cartridge. sometimes you can get a build up of hard water inside the valve body and that will cause leaks. just dont over do it with the sandpaper and dont anything more abrasive than 1500 grit.

New House, two out of three bathrooms have same problem no hot water on Moen bath tub valve. Pulled valve out and flushed reinstalled valve still no hot water. Tried new cartridge still no hot water?


Your problem sounds more like a scald guard adjustment than a cartridge problem. under the handle is 2 plastic parts that have gears on them. they are adjustable to limit the range motion of the handle. basically, it stops the range of the handle from turning all the way over to hot. on the chateau the adjustment is on the metal sleeve. the gears are under the handle on the positemp.

I installed a Moen 82496C faucet. I have great hot water flow, barely any cold water flow. I have talked to rep from Moen about this problem. They have now sent me 2 new replacement cartridges. No luck. Without the cartridge in I have great hot/cold water flow from the valve. When I put the cartridge in, the same problem...help me please..Marc


It sounds like the valve is a manufacture defect where the cartridge sits.Hope this helps.

The house was built in 2003 and has been unoccupied since 2007. We moved in this weekend and found that the shower valve only allows hot water. When you turn down to cold supply it shuts off all water. The plumber indicates that he is unable to replace the cartridge but instead needs to replace the entire valve assembly removing tile etc. We also have two single lever moen shower valves that the plumber did replace the cartridge in the problem was opposite in that the valve only allowed cold water. Is there something differnt regarding the two lever moen valve? Ours has one lever to control water flow and temp, and the second lever controls vaious alternate showere heads. Advise?


Hello! Cartridge can be replaced...Turn off water to the valve and open it up...Clean the inlet ports on the cartridge...Shake the cartridge; It should sound like a spray paint can...If not replace the cartridge...The problem is a build up of minerals in your hot water tank...Tank needs to be flushed every couple of months...Hook a garden hose to the drain line and open the valve...Let it run until it is clear... Guru........saailer

We lost water flow to our bath tub faucet and associated shower head recently. I took off the shower head to confirm that the filter wasn't blocking flow there. We then had a plumbing company come out and take a look and they believed the issue to be with our Delta water mixer cartridge as there was a build up of sediment on the intakes and they could not clean it enough. I was able to track down a replacement cartridge but still nothing coming through. I then returned that in case the new cartridge was faulty. Still nothing. I turned the water back off, took out the cartridge completely and turned the water back on. Water comes gushing out of there into the bathtub so there is 100% no problem with water getting to the bathtub. If in theory the cartridge is working then after the handle is turned on it should then be pushing the water into the opening that goes into the copper pipe going to the faucet and shower head. These are new copper pipes which were put in within the last two years so it is impossible for there to be any kind of buildup on the pipe (sediment would not have been able to pass through Delta cartridge anyway). Water is not leaking as I can see the plumbing in the closet behind the tub. Drywall had been ripped out when plumbing work was done two years ago and not replaced. If the pressure was causing the water to get displaced anywhere else I would see it back there, but it is dry as a bone. Is it possible that all three cartridges (original plus two replacements) are all faulty? I have proven that water is getting to the point where the cartridge is installed but not getting beyond the cartridge. Is there something else I am missing? Installation of cartridge is cut and dry. It will only go in one way. I don't even have the whole assembly on while testing so I can leave the adjustment screw off and just using Vice-Grip to allow me to turn handle the whole way. Help !!!!!!!!!!


I'm thinking that the cartridge may not be turning with the handle. After attempting to turn the faucet on a few times, see if the teeth on it are worn.

Moen water flow restricted and only warm


Not sure about your particular valve, but most newer shower valves have an anti-scald limiter that stops the handle from turning too far to the hot water side. Check for a ring or a pin under the handle that can be set in different positions. It will need to be moved clockwise to allow the handle to rotate farther to hot. Hope that helps. If you have trouble finding it, try looking up a diagram for the valve model.
