What he said.

Turn the 2nd handle off and then quickly turn the 1st handle on and see if it leaks continously.

Do take the step of first closing the outlet isolation valve, before you turn on the system. If the PVB isn't leaking, then you would look elsewhere for a reason you have pressure too low for the PVB to seal.

I've installed those, but never had leaks without there being some debris - freeze damage is excepted - if the leaking is from a testcock, you replace it.

leaking pressure vacuum breaker

I have a Wilkins PVB model 720A and am trying to turn my system on but the breaker keeps leaking. I have taken it apart and there is nothing in it causing it not to work. Does anyone have any advice for me?
