I just picked up my gulfstream 5230 BT Cruiser and took it on a 350 mile "break in" trip to test all the onboard equipment. Prior to delivery I asked the dealer to install a Surflo smartsensor 5.7 water pump.....(supposed to be silent). Well.....the rig worked great but the water pump sounded like a distressed buffalo!!! Before I trek back to the dealer is there something simple (stupid) that I should try? I turned on all the faucets and shower and the pump is loud almost as if it where trying to prime itself....
