Product Reviews

Rated 5 out of 5 by from No problems here. The product is fine. However, be sure that your plummer installs it correctly as after all was said and done, my hot sign was my cold and my cold was the hot sign. I guess my Plummer got them mixed up when he installed it. It's not a big deal that I can't live with it, so I am not ripping the tile out for it but if you can avoid that please do.

Rated 5 out of 5 by from Necessary Valve Purchase One of the best things about ordering from Faucet Direct is that they tell you when you need to order a supporting piece of equipment. I'm no plumber and I don't know what is required on the back side of my shower wall, but Faucet Direct showed me everything I needed to complete my order. Thank you for making my order complete so I didn't have to call the plumber out twice!

Rated 2 out of 5 by from Not what you think even though the product is listed as 1/2" IPS connection it is only partially that the water supply lines are IPS but the transfer valve is still solder and they give you IPS fittings to solder in yourself. Also mine came in damaged even though it was in a 2nd box and I had to take a hammer to it to get the valve assembly bent back out to accept the IPS fitting. Would most likely have sent it back but job would be held up.

Rated 5 out of 5 by from DEPENDABLE RELIABLE BEST PURCHASE Very sturdy valve.Simple and very helpful setup instructions.This baby saves you time energy and frustration.

Rated 4 out of 5 by from Just FYI The valve is fine. And Faucet Direct was great. Just one warning... they sell 2 valves, one is a copper connections and one is ips (threaded). There are 4 connections on the valve, and the ips only has threads on 2 of them. Defeats the purpose of ordering the ips valve. If I had the stuff to join copper, I would have ordered the other valve. Moen needs to keep all 4 the same type of connections on the same valve. Or warn people.

Rated 3 out of 5 by from So far so good.Low water pressure when body spray and shower head turned on.

Rated 5 out of 5 by from Simple, elegant, great value! This valve was a real problem-solver for me giving me the ability to switch between my regular showerhead and handshower on the opposite side of my walk-in shower. So many other manufacturers' needed a shower valve and seperate transfer valve and 3 times the total cost of this Moen and it's trim kit. I should have known better and started my search with Moen. FaucetDirect is a great company to deal with too!!!

Rated 5 out of 5 by from Great Valve This is actually my 2nd purchase of this product as the 1st one turned out very well as you can run the shower head and four jets off of it in unison if you want to. Family loves it and so it's going in 2nd bathroom remodel project!
