My city water pressure is a paltry 40 psi on my side of the 3/4" meter. My service line is new 1-1/4" sch40 pvc. I'd like to have at least 50 psi for the second floor bathroom but would prefer to not have up and down pressure variations. I don't think we would ever exceed 10 gpm flow and would only rarely exceed 7 gpm, assuming two showers and kitchen sink in use simultaneously.
I was thinking I could install a check valve and a jet pump to pressurize a tank up to 70 psi or higher and then a pressure reducing valve to moderate the pressure to around 55-60 psi output (in the basement) to then feed the house.
Given a typical usage rate of 7 gpm or less with 40 psi from the city...
My initial questions and thoughts were:
1. What capacity tank? Only a portion of the tank capacity would be available before the pressure dropped and the pump would need to come on anyway.
2. What capacity pump? Bigger is better to a point. Bigger is mo money. If the pump can supply 10 gpm or more at 55 psi or more, do I actually need a tank other than to buffer the initial pressure drop as a fixture is opened and then the surge as the pump turns on? and therefore a smaller tank like 20-30 gal?
3. Once the tank pressure drops and the pump comes on the pump is basically in continuous duty mode. Can these pumps take that kind of usage without becoming a maintenance problem?
Am I on the right track?
What are my other options for boosting my pressure? (no little blue pill jokes)
Thanks
