There is a hex head allen screw on the underside of the handle. Loosen it and gently pull out on handle while tapping on handle body with non-marring tool Thank you.

probably have a kink on how water line feeding valve..if possible to cut drywall bhind tub valve and inspect pipe at bottom plate...moen faucets are equipped w/ anti scald device, pressure balanced (newer models) and this could cause cold water to overwhelm hot water...

those are just trim kit numbers those do not show the valve.

check all solder,threaded,joint's.i'm pretty sure that model has shut off's to the left and right of center.check those as well.water will travel in some strange way's,yes alway's down but it will follow some strange path's. p.s.take a look /check your shower arm.

Call moen and give them your model no. they will send you a new cartridge free of charge. if you can't wait local stores like lowes will have them. Turn off your main water shut off valve and take off handle, then with some pliers take off brass ring, the cartridge will pull out. First notice the notch it rests in and notice where the hot water adjustment disc is. Assemble the new one the same way, put some vasolene on orings and reassemble. hope this helps.

the joints at the body are not tight or leaking.Call him back to fix.

you need to change the cartridge

Here is a possible solution for you. First go out and buy a Moen cartridge puller tool like this:



Next follow these steps:

1. Turn off the water to the valve.
2. Install puller and rotate cartridge several times.
3. Gently pull on cartridge while slowly turning.

This should work. If the center of the valve pulls out continue below with these suggestions:

1. Remove center piece from tool.
2. Place the brass feral to the end of the tool as shown.
3. Insert this part of the tool into the valve all the way as far as it can go.
4. Turn the tool until you hear a click or tool feels like it turns the valve.
5. Pull on the tool gently while turning.

This should get the job done.

Also here is some information for you about your valve:

Hope this helps and please rate this suggestion.

Replacing the cartridge should solve the problem, the balancing spool is stuck, replacing it will solve the problem. The valve should look like this http://www.moen.ca/shared/pdf/3170pt.pdf . I have unstuck the spools in the past, soaking it in white vinegar will help to remove build up.
