I currently had the pleasure of troubleshooting my water supply system. After replacing the well tank, pressure gauge, and various fitting due to an unexpected cold snap, i noticed that my supply line from my well to the house is 1" PVC all the way and doesn't reduce to 3/4" PVC until just before it enters the house (distance of around 156'). My water pressure has been marginal before and after the tank change and i was wondering if it could be because the line doesn't reduce down to 3/4" PVC somewhere other than right before it reaches the house connection (mobile home)? I know that 1" PVC will carry a higher volume of water, but i'm also thinking that reducing it down one size would help the pressure increase to my fixtures?
