Might move this question to DRV topic to get more replies. In any event unless added by a previous owner there is no onboard water pressure regulator. I think they are supposed to pressure test the trailer plumbing to over 100psi so you should be OK. In my 07 Elite Suite the plumbing leaked a lot (the flexible rubber garden hose type outlet from the pump was especially leak prone) so I always used an outside regulator set at 40 or below. I tried never to use the pump as it would almost always overpressure the system and cause a leak. I think mine was unusual in that regard as others never seemed to have the leaks mine did.
