Question: can i use these with copper pipes?
Document: I trust this plumber knows what he is doing. So this is just a warning that while you may need to buy valves to go with the Moen faucets, you'd better make sure the Moen valves will work with your pipes. I do not know if Amazon will take these valves back, now that the packages have been opened and I think the plumber actually tried to use at least one of the valves before determining he couldn't.
I am an experienced plumber. The trend is to use the quick connect tubing. I am not happy about how the &#34;O&#34; rings could fail years after the installation. Otherwise the system is well made.
I bought the M-PACT rough-in valve to use as part of a bathroom remodel at my home, and was pleasantly surprised at how easy it was to install. Everything worked exactly as it should the first time I turned the water on, and it works flawlessly with the Moen trim kit I bought to go with this. As another reviewer pointed out, I like the M-PACT concept of being able to switch out the trim kit should I decide to do so in the future.
This is the valve assembly that goes with the faucet we purchased for our new bathroom. There are several different Moen faucet sets which use this same valve set. We chose the Eva T6420BN.I am very pleased with Moen's new valve and faucet design. It was extremely easy to install, as compared to so many others I've done, and the design and quality of the materials is excellent. I am not a plumber by trade but I was able to install it without difficulty using a few simple hand tools.
there is not much one can say about a rough in valve. It is in my sink and seems to be working well.
received promptly and was happy with this product. Had plummer come in and get everything set up and all is working fine
and by the time we opened it and figured out the plunger was not the correct one, it was too late to return it. I replaced the plunger assembly with one we bought at Lowes.
Working well, good buy
When I think of the hassles I've had installing faucet vales over my life time. This is an exceptions product, so easy even a cave man can do it. I'm soooooo happy!
What do you write about a drain assembly. I needed it for new bathroom and it seems to do what it's supposed to do.
Answer: no
