I think its just the WG dumping boost , at the set pressure. At 10 psi you just don't hear it as loud , at 18+ things start to get serious. you here the pressure dumping. You can try turning It up some more. At 21 or 22 psi. You won't hear that noise until the WG opens and starts to dump.
I'm going to attempt it today
