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

Answer: 
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.

I have a backflow preventer (required by law where I live) on my sprinkler system. My current unit keeps freezing up in the winter. I would like to replace my existing unit with one I can bury.

Answer: 
Hello OSU_EE and thank you for your question.
The Watts 1 in. Backflow Preventer Air Admittance Valve (Model # 007M1 QT) cannot be buried underground. The handles may rust (due to weather conditions over time) and the valve cannot be tested in the event of an inspection.
Best wishes on your project.

Rated 4.0 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Watts 1 inch back flow preventer Installed device with no issues related to the device. Output connector, PVC, has a slight drip that needs to be corrected and still awaiting certification before calling all good. September 1, 2015
Rated 4.0 out of 5.0 by 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!! April 25, 2012
