The hot and cold are reversed on our single handle shower (no tub faucet -- shower only)


Hot on left.
Cold on right.
Some single handle faucets have bleed-over where both hot and cold enter mixing valve each time handle is turned on, even when faucet calls for just cold or just hot.
Otherwise maybe a do-it-yourself plumber got pipes backwards... or maybe the tub used to be on other side of wall, and tub was moved during remodeling but pipes were not changed.

To fix problem:
First of all, turn off shower faucet. Turn on Hot at sink and put ear against shower faucet listening for sound of water flowing through the mixing valve.
If mixing valve is working fine, you need to open wall and investigate more.
For example if you have access door, reach in and feel which pipe is hot.
Pipes might need to be reversed if problem comes up in home inspection, otherwise the problem will not harm anything.

We recently installed a Moen single handle faucet in a refinished shower after having a plumber replumb the front of our house. Handle appears to be properly installed. Now there is no hot water or even water flow at all when we turn the handle to hot. The cold water in the shower flows just fine. There's a sink in the bathroom as well which has hot water. What is most likely the cause when there is no flow of water at all when a single handle faucet is turned all the way to hot? Hope this makes sense.

how to adjust temp control for sigle lever shower control


Temp control is only accomplished by moving handle to desired position. If your asking is the hardware that in behind the single lever going to allow for adjustments, then the answer is NO. I installed the same into one of my bathrooms several years ago and I know what I am talking about. The single handle on that type on mine starts off then cold to hot. Problem is I wait for hot water to max so I can adjust it down to a comfortable temperture to prevent being burned. I refuse to buy one for other tubs. The 2 handles make temperture much easier with less wasted water used until its hot. Remember if you decide to replace with a two lever model then you will have to replumb the pipes for a two handle hardware unit (thats the stuff behind wall that your single handle goes into to which is currently plumbed for a single handle hardware unit.)

moen single handle valve tub/shower


The Moen Posi-Temp Valve is a pressure balanced valve and when not used for long periods of time they can stick causing only cold or hot water to pass through the valve.
A New Posi-temp cartridges can be purchased at most plumbing supply houses or big box outlets such as Lowes or Home Depot.
As long as you had cold water before, a new cartridge will solve the problem. In the future it would be wise to occassionally operate the valve at least a couple of times a month in order to keep the pressure assembly from becoming lodged in position. Just follow the instructions included with the new cartridge on the proper removal of the old cartridge and the installation of the new cartridge. a little silicone grease inside of the valve before installing the new cartridge will also help.
Be sure that there is no particles of the old cartridge left in the valve.
