I am on a city system with only 18lbs pressure from the street. Started with 1/2" copoper line from the street and replaced that with a 1" copoper line. Now 20lbs pressure.......big whoop!
Next bought 1/2 hp shur jet pump with 20 gal bladder tank and check valve. Pump runs but relay chatter on and off rapidly. Can't seem to find an adjustment setting to stop it. Thought maybe it was running out of water, so I put a 40 gal tank before the pump, but same problem. Any suggestions? Much money and time spent and pipes looking like a space shuttle, but no water pressure. Gary
