I would not unless you have one with a gage on it. I prefer to keep it at 60# if the CG has it. At least if set at 60 I'm safe and will get all the WP I can get. I have skipped it but ran the water first to see how much pressure there is.

Opps I should read the posts before responding.

I was thinking of 60 - 65 psi myself. Thanks for sharing

I was thinking the fixed one I had was at 40psi but based on what i read here it's 48 to 52 ...shower worked well for us with this one on. Doesn't mean I won't buy and adjustable one

Amazon.com: Valterra A01-1122VP Lead-Free High Flow Water Regulator: Automotive

The wild temp fluctuation is due to the the safety cutoff switch (burner shutdown), due in to an outlet temperature above 125F, usually caused by a lower flow than 1 gpm, which is in turn caused by either an lower supply pressure than Girard recommended 45 psi, or excessive flow restrictions added to the system. Also, the burner will switch from high to low when the inlet water temp is over 70F, and back to high when the inlet temp is under 65F. (Ref: http://greenrvproducts.com/wp-conten...4-09-20102.pdf)

A Y-valve (splitter at the faucet will not cause nearly as much pressure drop as a long hose length (50', when only 25' is needed), or ells and valves that are added to the system.

As far as I know, there is no internal pressure regulator, and if you don't have one at the supply faucet (hopefully adjustable), you could encounter a higher than normal pressure that could damage the water system components. FR has tested the Berkshire water system to 95 psi with no failures (probably thanks to the PEX tubing), but doesn't advertise that, since there are third party system components (like the Girard WH) with lower operating pressure limits (the warranties of which could be violated). And yes, a supply pressure regulator will cost you some dynamic pressure loss, but is advisable. Be sure to install it upstream of any external water filter you might have (which doesn't cost you as much of a dynamic head loss as you might think).

I suggest that you go to Girard's website and read about the principal of operation. The bottom line is: you need more than 45 psi to make it work right (43 psi, in my experience); you need to set the burner control to "Low" in the summer (when inlet water temperatures are high, due to the hose lying in the sun - water comes out of the ground at the same temperature year-round; and you can set the burner temperature to "Auto" when the ambient temps are cold (fall mornings, etc.).

Finally, since the pressure regulator gauge reads the regulator outlet static pressure (i.e. no-flow condition), you need to check the supply pressure with a separate gauge. I invariably have problems below 43 psi, and no problems higher than 50 psi static supply pressure. I have my supply regulator set at 52 psi static pressure.

Southern Roamer don't be confused by the reference to a low switch or an auto switch. Those are from a Gen 1 Water heater and you most likely have a Gen 2. You will have a dial to control the BYU output for the heater.

Thanks for all the advice. I will check to see what type switch I have and definitely purchase an adjustable pressure regulator.
