Moen shower handle keeps turning it wont come to a stop

Question moved from Vacuums.

If the pictures here are correct, there are 'variations' to the 1225 cartridge. No, it doesn't sound as though yours if fitted correctly. There is normally a stop on both sides of hot and cold to stop it spinning 360'.

remove and turn cartridge 180 degrees then re-install

If this is a Moen posi temp valve you may need to adjust the temperature limit stop. It is located under the handle. Usualy a plastic peice with grooves in it so it fits in another peice in the valve. If I remember right you pull this peice out and turn it counter clockwise to get more hot water. Do this in small increments and reassemble and test. I hope this helps.

these valves can be adjusted by removing the handle and adjusting the white gear that regulates the hot and cold that come out, try going more to one way if it gets colder then go the other way.

You can cap the lines at the tub faucet to rule out tub faucet. It maybe mixing there.

Faucet may be bad also the safety stop will alow you to change water temp it can be tricky to adjust water temp.

You can try to rotate the first plastic ring to the left of center a few teeth, this will let the handle advance alittle more to the hot side.

are the handle extensions on the cartridges all the way. i know sometimes the moens are a pain after you put the trim on to get them on and seated right so it actually spins the cartridge. also check the cartridge alignment the cartridges have little white tabs on the sides that correspond with a slot in the valve body if they aren't aligned it won't shut off either

change the washers first if that don't work change the inserts buy all at same time and return if not needed . Thank you for useing fixya please rate me

make sure when you turn on the hot and cold shut off valves all the way and turn the moen on after that. Some times I would get that problem if I turned one(either hot or cold) off then tried the shower.

Hello, first if any water supply hot or cold is turned off, you will experience trickling as you mention. You must have both cold and hot in order to adjust the temperature on your valve. if you had a plumber intall this unit you should ask him to adjust it. Otherwise here is how:
Rotate the handle counterclockwise to stop and let water run till cold water is purged, check
temperature. Rotate handle to off, remove handle parts (see Disassembly in your manual) and temperature limit stop, rotate clockwise to decrease and counterclockwise to increase maximum hot water temperature, reinstall temperature limit stop and handle (TIP: Do not screw handle in until desired maximum temperature is achieved) Repeat steps until desired maximum
temperature is achieved
