This particular volume control design has issues Rated 3 by Sally No, I do not recommend this product. I have 11 CFG manufactured faucets all throughout my home and have been happy with them. They have been very trouble free. They were installed in 2009. I have 3 showers that use this particular model valve which is made by CFG in Ohio for Moen. The design on this pressure balance mechanism tends to cause it to get stuck closed, in particular on the cold water side. Unlike all the others you find including those made by CFG and Moen that use a turn screw for adjustment this appears to be an "auto" adjusting design that is an o-ring valve that when even the slightest hard water deposit or sediment builds up it seizes closed eventually slowing the cold water to a trickle.
With some tight work I was able to remove the cap (the parts that look like a bolt on the water inlets) and completely removed the regulator from the cold side and then replaced the cap. So far I have found no negative to doing this and very happy to have normal shower pressure back.
I would continue to use CFG manufactured faucets. Although, I cant recommend this particular design of the pressure control valve part on the water inputs. Look for the design that is adjustable with a screwdriver. The main control valve is fine. Originally posted on plumbersstock.com Oct/2016
