I just had a 5 bed/bathroom two story plus basement home built and have a question about my water line size. Originally they installed a 1 inch poly line which was damaged.....after the fact I realized they replaced it with a 3/4 in line (and of course my builder/excavator both assured me it was fine) PSI at the main is around 120. Distance from the main to meter is 35 feet and distance to the house from the meter is 150 feet (house is downhill about 10 feet in elevation). 2 feet after entering the home it converts to a 1 inch regulating valve with 1 inch PEX trunks for about 10 feet In the basement ceiling which then goes to 3/4 inch another 30 feet in each direction. I have the PRV set at 70 psi in the basement.
I notice pressure issues mainly if 3 showers are running at the same time or 3 hose bibs are running sprinklers. (This doesn't happen much but my wife has mentioned pressure fluctuations while showering).
One or two showers at a time are fine which is why I don't think it would be worth digging my yard up at this point.
Is there anything I can so inside the house to improve this problem? Extend the trunk lines to 1 inch? Extend 1 inch lines all the way to the water heater?
