We had a new hose bibb installed last week. I’m not familiar with this type of vacuum breaker. Today we hooked up our pressure washer to it to clean the patio furniture, and the water slowed to a trickle after a few minutes, and now the faucet doesn’t work at all. I called the plumbing company to ask about it, but the plumber hasn’t called me back yet. Did we mess it up by using the pressure washer? He didn’t mention any special instructions about it when he installed it. thanks.
