My PVB is leaking from the canopy. I disassembled the PVB components (bonnet, washer, o-ring, poppet assembly, spring) and checked for any damaged or worn items. One thing I noticed is that the rubber piece on the poppet assembly has a slight opening (slit). I did see this opening on poppet assemblies of other PVB diagrams, but not the 720A. It looks like it is manufactured this way, but want to verify. Can anyone confirm. Unfortunately, I can't submit a picture at this time. If this slit is correct, wondering how the PVB works to prevent water from going through this slit. Any other ideas of what could be the cause of the leakage?
