I'm trying to pick out a new valve for my shower, and I'm pretty set on a Moentrol. Moen produces four differnet models:
- Two 1/2" IPS Models: 3510 and 3550
- Two 1/2" CC Models: 3520 and 3570
Their spec sheets are available at:
The only differences that I see in the specs are "integral checks" compared to "integral check stops"
Can someone please enlighten me on the differences between the 3510/3520 line and the 3550/3570 line?
