Review on Pfister 910-9000 Ceramic Valve: A Reliable Solution for Smooth Faucet Operation by Derek Davie

Great product, served its purpose. It's hard to know if this is correct if you don't know the model number of older faucets. They need a chart or something to show on the page; I just calculated based on the measurements given. ALSO: no instructions for replacing either of the two with the cold side; You simply remove the retaining clip, flip over the metal band (which is held on the clip) and reinsert the retaining clip. If you look at the old one you took off you can see what it should look like. This must be provided. Newer models do not have this setting. Much luck!
