We had a new house built about 500' uphill about 50' above the community water system's meter. We used 1 1/2" PVC and are getting various water pressures from 18 to 45 lbs, but most of the time it is 20-25 lbs with nothing in the house running. Water company says there is nothing wrong with their system, but has not put a gauge at their meter. My gauge is at the inlet in the house before filter and water softner. I believe we should have 35-40 lbs into the house. Any suggestions? Maybe a booster pump?
