I am installing a water powered backup sump pump and code requires a 3/4" reduce pressure zone (RPZ) valve on the water supply to the sump pump. The two brands that seem pretty popular on the internet for RPZ are Watts (model 009M3QT) and Cash Acme (cash-flo RPZ II). What brand has a better reputation for quality since this is an important piece of equipment? Can anyone shed some light of these brands from a quality standpoint?
Which brand for RPZ, Watts or Cash Acme?

Watts or Zurn, usually because of parts availability.

Watts over the rest. Zurn is good. Cash Acme is good.

I have stock
I don't like watts because I have short fat fingers that make it very hard to service there RPZ. I find Wilkins/Zern much easier to service.

So other than potentially being harder to service, Watts is a good quality brand that will be easy to find parts. I have heard that some people use dual check valves with the atmosphere vent between the checks in lieu of a RPZ for protecting the water supply on a water powered backup sump pump. What are you thoughts on using dual check valves with atmosphere vent?
