Pressure Vacuum Breaker
Posted by Aaron on October 14, 1999 at 04:28:41:
Recently my sprinkler system started making a loud
vibrating noise. I believe it may be the 10 year old
pressure vacuum breaker valves (Wilkins), but I'm not
sure.

Is this a common problem with pressure vacuum breaker
valves or should I look somewhere else for the source
of the problem?
