I have been reading other posts and it seems that the Renator pressure regulators have been an issue for some. We're on our third one. They stand by their product and have replaced them each time we've had an issue. But our water pressure is very low throughout the trailer even though we have it set to 45 psi, which is the highest we'll go because of many water leaks we've had in this unit. Should we be trying another another regulator. If so, what brands have people been having good luck with?
