I looked up the specs summarized below.
Old Surflow 2088 2.8 GPM, 3 AMP draw 40 PSI
New Surflow 4008 3.0 GPM 7.5 AMP draw 55 PSI
I have two concerns if we are boondocking the AMP draw on the new is over 2X the old also I don't know what my 1972 trailer original pressure relief valve is set to, IE is 55 PSI too high for my unit.
Has anyone else switched to a surflow 4008? that boondocks? is the higher AMP draw a problem?
I have the 4008, though I didn't keep any of my original plumbing. Very unlikely you'd notice a difference between the power draw of the two water pumps while boondocking. Yes, it draws over 2x the power, but it's only ever on for a few seconds at a time. You'll run out of water way before you run out of power.
