Nope. Go around and open your faucets one at a time until the air quits and then move to the next one. Don't for get the shower and the toilet. I would even do the outside shower faucets. If it still wants to run or surge you could have something wrong with the pressure shut off switch in the pump or it could be sucking air at an inlet fitting. I have had the later problem with every RV I have ever owned. A good way of finding out which fitting it causing the problem is to wet a rag and go around and hold it over the fittings until you find one where the surging stops. I have had the water heater by pass valves suck air also, so be sure to check them.
