Here is my setup: Well pump feeds a 3800-gallon cistern on the high-elevation portion of our property, which is 100' in elevation above our commercial/residential building. The building is fed from the cistern with 2" white pipe, and I get the expected 44 psi at the building. The 2" pvc feed from the cistern is converted to a 1-1/2" Uponor PEX main header that runs the length of the building with tee's supplying all the various water needs.
I would like to boost the building's pressure to 60 psi. We have a commercial hot water dishwasher, and it just barely meets the minimum pressure required. (We Occasionally get a low-pressure error code.) We also find on our wine production crush pad that our garden hoses feel like they have a bit of a weak stream.
It seems logical that I would install a booster where the water comes into the building, where the pipe converts from 2" PVC to 1-1/2" PEX. The pump would only need to increase pressure by 20 psi but would need to meet the potential high-flow needs of a wine-tasting room, wine production space, and a three-bedroom residence.
I'd love to hear your thoughts.
