Does on-board water pressure regulator protect against excessive air pressure?
I dropped by a local RV dealer (non AS) to pick up a tube to connect to the input of my on-board water pump, to pump RV antifreeze into the water pipes. I mentioned that I had previously used an air compressor to clear out the water which led him to say that they didn't do this nor did he recommend it to his customers because of the risk of damaging the piping due to excessive air pressure.
There is an integrated 65 psi (max) water pressure regulator on the AS. Does anyone know if this regulator will also protect against excessive air pressure when winterizing? If the regulator mechanism is a diaphragm, will it work similarly no matter the nature of the "fluid"?
