Use at least 1 size larger tubing than the size of the pump. Read the specs to be sure the pump can push the 40' lift (and don't just guess, verify the lift). As stated, mount the transfer line to eliminate any dips that could freeze. What is the head rating of the Seaflo 7 gpm pump?
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
