Another low water pressure question. The problem has existed since living here (6 yrs), but I'm prompted to fix it after watching Rich T. address low water pressure numerous times. I have a well, water softener, and whole-house carbon filter. The pressure switch is 30/50. We get reasonable pressure at some locations, but not others. Kitchen sink is low (won't even let the faucet stay on the "spray" setting). One shower is low. Outside faucets are low. One plumber said I need to re-pipe the water softener and filter bypass loop from 3/4 to 1" pipe and valves - $500. I've seen Rich do pumps and other things, but never have to re-plumb to bigger pipes. Before I do that, I want to have confidence it would make a difference.
