This is not a constant pressure pump & I am using 2 119 Gallon tanks to reduce the # of pump starts particularly in the winter.

They will run a little bit, a lot of the time to keep the pressure constant. I think it might be more efficient to use a pressure switch and regular pressure tank. Anyone with experience in this?

I am curious as to feedback on these, has anyone used them? Soft start, digital controls, easy programming, stainless steel, 3-year warranty, & includes a pressure transducer, so no pressure switch required. My pump guy says he has only had 1 issue on 1 pump in serval hundred installed. Almost sounds too good to believe. A bit less $ retail than a Grundfoss but supposedly a whole lot more reliable. A 1 HP motor 20 GPM pump draws 4.7 Amp/240 VA as it hits a 60 psi cutout [1,128 watts peak] though I will set to 30/50 psi.
