I believe the tech at Oasis is not correct. I went to the service manual for Oasis units and found that while I am certified on Aqua hot and not Oasis, the systems are very similar in controls. There is NO pressure switch and NO system of any kind that will let the Oasis unit know what the fresh water pressure is. Just like Aqua hot units. In the operating manual and the Service Manual, there is NO spec or anything that brings up pressure for malfunctions. I could find NO spec for minimum water pressure or maximum water pressure requirements. The 120 and Diesel both function from their respective tstats and nothing else will stop their function. I would remove that regulator and test if it still functions. I would also call Oasis and talk to another Tech and ask if the water pressure is true and to e mail the documentation for their statement. The reason I would do this is because something caused your system to fail and I doubt it was water pressure. It was a coincidence that it worked after you installed the regulator. Doug
That's exactly what I suspect. I'm leaving the regulator on for now but if it happens again, I'll know to look further. This is the first campground in 5 years I've ever been to that had decent water pressure.
But, I've noticed that the water is much hotter now that I've installed the pressure regulator. So there may be something to the tech's analysis. I don't think it has anything to do with the pressure, but maybe more to do with water flow from either the water pump or city water connection confusing the tstats.
ALL on demand Hot water systems---the slower the water passes thru the copper heating coil in the tank the MORE heat it receives and brings to you. So 45 PSI is the "norm" for water systems. That is what the non adjustable regulators are set at. So, yes, you will see hotter production and leaving the regulator in place is the right thing to do. Doug
