Is there an internal water pressure regulator in the newer coaches (05 and up)? I'm talking about behind the city water hookup where the pressure unit can't be seen.
Also, when you are hooked up to city water and turn on the pump is the pump adding to the city water or is it simply pulling from the tank. It seems that if the pump is used we have more pressure. Mistery to me.

Not according to the schematic that came w/my '06, nor per my dis/re-assembly when installing the RO unit.
I pulled the city water fill out to install a pressure gauge tap, & it is a backflow preventer (basically a neoprene flapper valve in line w/the hose connection) only. No regulator encountered.

Electric pump will keep ~50psi on the line from the tank into the house, but if city pressure is higher, that will control & pump won't add. If city is lower, pump will bring it up to ~50.
