Question: Reviews say this needs 6" walls or it stick out too far.  Is this true?
Document: We bought this with the Moen trim kit T2152 and the instructions do not say how far into the wall the valve needs to be for this trim kit....unfortunatly, we are stuck with a shower handle that sticks out about and inch and a half from the wall - ugly. The wall was already finished so without tearing it ALL apart it can not be fixed. Moen sells a part for $80 + that will take up about 1/2 inch, ugh!This was a professional who installed.
We thought he should have known better. Still, we are stuck.Found reviews on line that said you need a 6" wall for this trim kit and valve.
Shower valves have been around for a long time so you would think designing one would be easy...well...obviously not. This valve is terrible. After 4 months the hot water disappears and the cartridge needs to be replaced. FYI, the cartridge costs as much as the valve. Also, as others have reported how the cartridge and valve are in there make your shower handle stick out at least an inch from the wall. There is no room in a wall built with 2X4s for it to fit properly.
Works well with Moen Eco Friendly shower facet. No freeze-outs when others use hot water! Would purchase again if needed.
This PosiTemp valve is absolutely a nightmare for my family. The hot water started to be less hot than it originally was six months ago. It was summer so that my kids were still showering in lukewarm water. About a month ago, it became unbearable and we had to hire a plumber to come get a look. The first plumber told us to pretty much take the wall down and replace the valve. Finally, the 3rd plumber told us to replace the valve cartridge (only $30 part) and recommended us to contact Moen.
Replacing the cartridge turned into a disaster due to the stem separated from the rest of the cartridge (which costs about $30 dollars by itself). Had to take a drill to carefully remove the rest of the cartridge but unfortunately wasn't careful enough and had a leak due to damaging the housing. Had to replace the housing with this and it worked like a charm.
Purchased this item for our bathroom remodel. Very smooth operation. Purchased Moen products for the rest of the bathroom - very pleased with the quality!
Moen was easy to work with, we went from one shower head of a different maker to moen. We didn't know if we could match the two makers up, very very different plumbing so I placed a call. Sure enough they had the &#34; transfer&#34; piece to make it work,  yea! Who knew?Moen knew exactly what part we needed, sent it to us, hubby installed it, and I now have the bathroom I wanted.From now on the ONLY fixtures I wlll buy will be Moen.
I'm hoping this valve is better the the instructions given to install it. There are three options for getting the spacing right for the wall. I tried all three and none of them were right. The valve spins infinitely, so trying to find the off position is nearly impossible. It wasn't until reading the trim instructions that I could see the indicator for off. It's a small notch on the end of the valve. I've installed plenty of faucets and this one has been the hardest. It's probably a great product, but the instructions are worse than Sauder's office equipment.
I replaced my leaking Moen Posi-temp valve with this one and it is working great! No leaks and it was easy to install.
