Fault Diagnosis: Support - Mira

The thermostatic cartridge is the part of the shower valve which control's the temperature of the water, therefore if there is a problem with the water temperature, the absolute probability points towards the thermostatic cartridge being at fault.

I would suggest you extract the thermostatic cartridge, remove any bits blocking water flow into the cartridge and then soak it in limescale remover. Put silicone grease on the O'rings. Install it again. If that doesn't work, the element within the cartridge could be faulty, so you could try replacing the element. If that doesn't work you will have to either replace the entire shower valve or replace the cartridge.

All of what I've said is based on the assumption that you are receiving hot water to your shower valve.

I've been working with thermostatic cartridge for many years and can tell you with confidence the above information likely applies to yourself. Shower Thermostatic Cartridge Spares

shut off your water and pull the cartridge out off unit...make sure you have no trash in cartridge...turn water on without cartridge in but only part way to see if you have water flow to value...then make sure no damage to cartridge or some of these have plugs that need removed on install of cartridge....you may need to remove test plug that is in there ....try this...good luck

Assuming you have a single handle valve, Moen has 2 types of cartridges. The Posi-Temp (replacement cartridge # 1222) turns on and off simply by turning the handle left to right and right to left. The Moentrol (replacement cartridge #1225B) turns on by pulling on it. Handle style does not aid in identification.

Buy your new cartridge before you start and buy genuine Moen! OEM cartridges can give Moen a bad name.

Once the water to the valve is off, remove the handle.

The procedure is the same for either type of valve so use the link below as a reference.

Firmly grab the temperature limit stop and pull it off the valve body. Using pliers, pull out the brass retainer clip. Place the notched end of the white plastic tool that came with your new cartridge onto the old cartridge and rotate as needed until completely seated on cartridge. Put a wrench onto the squared end of the white tool and turn back and forth several times. Remove the tool, grab the brass center of the cartridge with pliers and pull the cartridge out.

Briefly turn the water on ond off to flush the valve of any possible lingering particulate.

Insert new cartridge and use white tool to assure cartridge is all the way in then use the squared end to rotate the cartridge as necessary into an alignment position to reinstall the retainer clip.

Have you tried removing cartridge, rotating cartridge 180 degrees then re-install?

check your cartridge,and i believe your mod # 3175 has a balancing spool #1423, i think if i remember it is to the right of the cartridge,a large screw driver will get it out.

replace the cartridge if defectis not obvious.

You need to pull and replace the cartridge on your shower valve most likely. It varies by Make and Model, but generally, remove the handle, remove any sleeve around the center spine, remove the round trim plate, close the service stops, remove the retaining clip or ring, and pull the cartridge straight out of the valve body by pulling on the spline... or get a cartridge puller. Then take your cartridge to the store and get a new one. Flush the valve body by slightly opening both service stops and then install the new cartridge and reverse the process.
Generally this problem occurs when sediment has torn part of the sealing o ring on the cartridge. If you send me the make/model and/or a picture I will give you the specific instructions

Definitely try reversing the cartridge.

Make sure that you did not pinch an O ring seal when you were installing the cartridge. If so replace O ring. when installing new cartridge try putting a little Vaseline on all the O rings. It will seal better. It is rare but you could have purchased a defective cartridge. Never buy a cartridge if the package was opened because maybe someone just needed the O ring that is making your faucet leak :-)
