Product Overview

This double check valve assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to back siphonage and or backpressure. It's compact modular design means easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for contaminants at the service line entrance. This assembly consists of a bronze body construction, NPT end connections, quarter turn ball valve shutoffs, top mounted test cocks, two in-line independent positive seating check modules, captured springs, and replaceable check discs and seats.

Under what conditions would this item (007M1-QT double check valve assembly) be preferable to a pressure vacuum breaker (e.g. Model 800M4-QT)?

Assuming either one is acceptable under local regulations, how would I choose between them?
Asked by: BCautious
This valve would be preferable in installations where it is not possible to install the backflow at least 12” above the highest point of downstream piping.

Do you have any listing information associated with this valve, a list of agency approvals?

Per the County of Los Angeles title 17 a back flow device must be approved through USC. "Those seeking to acquire a copy of a current list of approved backflow prevention assemblies should contact USC Foundation for Cross-Connection Control and Hydraulic Research." Is this valve on that list? Thank You, Daryl Schay
Asked by: 71Surfbus
Hi Daryl, Yes, this valve is on the approved list according to the USC FCCCHR. The list, which is public domain, may be downloaded here for future reference: http://fccchr.usc.edu/

What this valve be a good valve to install for discharging a water softener to prevent any septic backflow?

Asked by: keels
No this valve is for potable systems, not discharge or waste lines….water softener backflush lines should be routed to drains, with an appropriate air gap to the waste line per local plumbing codes.

1 in. Backflow Preventer Air Admittance Valve is rated 4.4 out of 5 by 5.
Rated 4 out of 5 by from Used to replace a Zurn 1" bacflow preventer that had... Used to replace a Zurn 1" bacflow preventer that had slightly shorter female side test taps. Cut plastic downstream, unthreaded the failed zurn from supply then could not quite thread this on due to longer side taps. So had to cut and redo supply and downstream. Otherwise great, brass vs iron.

Rated 4 out of 5 by from This was a great replacement I was satisfied with the product, but one thing that bothered me was after installation I turned on the water pressure and saw that water was purging out of the center valve. I saw that there was a screw on the side of the valve (the one with water purging) and turned it halfway with a screwdriver. After turning on the water pressure I saw that there was no more water shooting out...case closed!!
