Huge temperature variation in Chateau by Moen shower only faucet

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'.

There is probably junk in the lines that has clogged mixing valve Moen is pretty simple to operate and maintain, however, before the new system was installed, maybe it was done, the water should have been run through the valve itself, without mixing valve installed. I am going to provide you with a video that shows how to remove the valve and, with a little help, you can remove valve and hopefully can clear the lines by running water, slowly, through the fixture, without the valve installed. You would want to try this anyway to make sure you have flow to the faucet:

Make sure all junk is cleared from lines and re-install your valve. If your cold and hot water is backwards, remove the valve and rotate 180 deg. and re-install. You can note the way the tabs are when you remove, and install in the same position.

To talk about your problem forces me to assume a few things.....If you allow the water to flow without cartridges and handles, the water must be flowing straight through the cartridge channels and out into the tub. It is not flowing through your tub spout or shower head when you test the water this way. If I'm correct, then the problem is isolated to the water mix operation. That means coming out of your spout or shower head. So now I have to ask a question. When you operate as normal (cartridges and handles installed) does your problem show up only on your shower head or does it also show up when operating out of the tub spout? If the problem is isolated to the shower head, try a head replacement. It may be partially plugged. If it's head or spout there may be something in the mixing pipe that only shifts around as pressure increases. I hope that is not your problem. It would require pulling those pipes out for inspection and most likely replacement. Nimsgame

You will need to replace the cartridge in the faucet

yes they do,part #1224

The problem is most likely with "the back pressure from the flow restrictor in the showerhead causing the spool in the cartridge to sense a false pressure drop. This is forcing the spool to shift, restricting a full hot water temperature from coming out." Believe it or not, I got this information from Moen. Their solution was to send out a valve without the multi settings of the original and that didn't work very well. I can only tell you that I used an older showerhead without the water saver feature and the valve and cartridge worked fine. The problem your having is with the cartridge/showerhead combination and short of using an older showerhead there is not a satisfactory solution. Maybe your plumber has a better solution.

The tl2383 is just a trim kit...if you have a 2 handle shower valve and it is moen then the number is 2919....you just need a new cartridge if you are not getting any hot water....it is a 1224 cartridge.

Turn off water main. remove round cap on face of handle, remove screw and pull handle. After that everything else can be pulled off easily. When you get to the diverter you should be able to why its stuck.
