Yeah, here ya go:


Moen 3330
Features 1/2" CC Connections


Moen 3320
Features 1/2" IPS connections

That's the only difference. I have not installed either of these before.

If I can make a suggestion for you, before you go putting all the work into plumbing that in, make damn sure you know the valve. That sucker has 4 sprayers and one main shower head. So think about that for a minute, and consider the supply inlet is half inch.

If it were me, I would make client buy the Grohe with 3/4" inlets (at the least) and of course a properly sized tankless water heater. But that's just me! Trim should be the exact same on either model.

I agree with James. That valve is good for one function at a tme. I have installed many of these valves. My usual installation is for a wall showerhead and a ceiling mounted sunflower shower head. With those two, I can use both at once, though I do not recomend planning for it.

Also, where did you see the valve with the treaded inlets at? Always try and go with soldered connections if possible. I see many people buying the threaded types at the big box stores.

We've installed dozens of those valves (both of them) and never had a problem, typically we run a shower head and 4 body sprays, and sometimes a shower head and a rain maker.

That Moen system is a life saver for giving customers a great treat in the shower for not a lot of money compared to alot of other companies products.

We almost always puchase the IPS versions because we like them to be installed using PEX.

Actually I even have that valve in my own house, no issues for the last 5 years.

Ya know, they do make a sweat to barb fitting, in all sizes. That's what I use for fixtures and going to and from copper.

also, let me ask you, what is the GPM on thoes sprayers if ya know?
Thanks

Mike Finley

I assume you are asking about the body sprays? But whether it's a body spray or a shower head they are all

2.5 gpm @ 80 psi each.

Gotta be according to the Feds conservation regulations right?

Actually I was thinking the sprayers were less than 2.5. I'm not sure with respect to everything but the main head.
