Question about Moen & One Handle Tub & Shower Faucet

Why does moentrol bath valve give hot water pointed to "C" and vice versa?

Bought a house with Moen Moentrol Single handle bathtub faucet that gives hot water pointed to "C" and cold water pointed to "H". Is the cartridge 180 degrees off? Or is water piping messed up?

    Thanks, I was hoping it would be that simple. I would think there should be an idiot-proof tab to prevent that happening, but maybe not.

I have reversed the cartridge twice now and cold is still left, hot is still right!

Had 1225 cartridge (wrong). Now have new 1200. STILL WRONG and have rotated cartridge.

Easy one.
Feel the pipes. The pipe on the right should be cold. If the pipes are correct, turn the cartridge 180 degrees.

Set screw for Moen 10066 Tube Stop Kit for my Kingsley single handle bathtub faucet went missing. I would like to know what size the set screw is.

If the limiter is portable, take it to your local "big box" store and browse through the hardware section to find a set screw that fits.

Moen single lever shower handle gives only hot water

A bit more information is needed; is this a Moentrol or a Posi-temp valve? You will need to shut water down to the shower. If it is a Moentrol, it could be an issue with either the cartridge or the pressure balancing spool. If you are at least getting water, I am going to assume that it is a Moentrol.
You will need to turn water off to the valve. Pull the cartridge and examine as to whether or not debris is blocking the supply holes of the cartridge. If your valve has built in shut off screws, you can slowly turn water on to clear any debris that may be inside the inlet port. I typically use a piece of PVC to go over the valve body so that water does not leak between the wall and the shower. Again, just turn water on enough to start it flowing.
If you do not notice anything amiss with the cartridge, it could also be the pressure balancing spool. If that is on your valve, it will be a flat head screw about the size of a nickel. Water will need to be off for the removal of the spool as well. Again, you will be looking for debris that is blocking water flow.
If this is an older Moen faucet, you may just want to replace the cartridge while you have it removed. If it is a push/pull, it is a Moentrol. If you have to turn the handle for water to come out, it is a Posi-temp. In my area, the cartridges run from $20-$40. However, Moen does offer lifetime on their cartridges. Lately, I have had a few more hoops to jump through to get the replacement cartridges from Moen, but they are still very pleasant to deal with.

You should be able to find a manual on Moen's website if you have the model number for the valve.

Sounds like the cause of your problem is the pressure balancing spool. Call Moen at
and explain the problem. They will send a repair part to you free of charge. the link below is a "blow up" of your valve.

When you turn to hot it doesn't come out. Cold does.

Assuming that you have hot water at other faucets the problem could be a varnish buildup in the cartridge. After shutting off the hot and cold water either by turning off the main or at the faucet stops (if equipped), remove the cartridge and soak it in white vinegar to break up the varnish. You can clean it up with an old toothbrush and make sure that it is working. It should rattle when you shake it. new cartridges are not very expensive so you can just buy a replacement at any home center as well. If you are the original owner of the faucet Moen will send you a free replacement cartridge if you call them.

No water from hot side

Balancing spool is froze up. If it is a moentrol valve then it has a separate spool that can be removed and replaced. Sometimes you can take it out and get it to break loose and working again by tapping it on a hard surface a few times. If not then it needs replaced.
If it is a positemp valve the spool is built into the cartridge and it will need to be replaced.

I have a single handle shower valve by Moen. Water is slowly leaking past the valve when shut off. I got the handle off but need to know how to further disassemble so I can replace whatever seal or o-ring...

there is a clip holding the cartridge in place. You need to remove that and then there is a little plastic throw away tool that comes with a new cartridge that you use to break the seals loose on the old cartridge....then you use a pair of channel locks to grab the stem and pull it out. The new cartridge should come with detailed instructions.
If it is a moentrol valve...the part number is 1225 and if it is a posi-temp it is a 1222. Moentrol you pull out to turn on and then left and right for temp adjustment. Posi-temp just turns to turn on and you turn from cold to hot to adjust through the temp range.

Something is caught in the stem. Make sure the stem is free of debris. Also check that the valve or cartridge is intact.
