1/5 Starsare you strong enough ? | This unit takes someone with "Jack Dempsey" strength to turn off. It is not for the weak or elderly. Besides freezing, after both valves were finally turned off, the unit apparantly seemed to still be leaking - therefore, the "main" water supply to the house had to be shut off.
Recommended? No.

Q:I purchased a repair kit for the Series 800M4 Anti-Siphon Pressure Vacuum Breaker and am puzzled how the parts go together correctly. It is clear that my valve has been leaking because the parts are not correctly in place. Can you please send me a picture detailing the correct way to install the white plastic valve, the stainless spring, the O ring, the black, screw on cap and black plate on top of the cap. I am also puzzled why the cap is designed like this, with a separate plate on top.Bob | Sunday, July 21, 2013
