Even with out the plumbing situation. Still check the meter turn it off and then turn it on. I have had several customers not aware that somebody shut down the water and then turned it back on. Even if you don't notice a pressure difference at your inside gallons per minute with greater volume (Sprinklers there can be a big difference).
The AVB is not supposed to be under constant pressure. Is it? I am not the AVB Police!!
You have to do the meter.
That is all I have GOT!!
