My house is on a well. About 30 years old. Never had any problems except once lightning blew up the submersible pump. No serious problems now. But, after a kitchen remodel, I notice the faucets are putting out pretty low flow. I measure a little shy of 1gpm. I realize that energy conservation has become a big thing since the original construction, but still, they are rated for 1.5gpm, although that's at 60psi, and they don't give a graph of flow versus pressure. Anyhow, I notice the gauge on at the well's pressure tank (in the crawlspace) only reads about 30 psi or so. Wondering if I should: replace the gauge and/or the pressure switch, adjust the pressure switch for more pressure, or what. I imagine the first thing is to replace the pressure gauge, to make sure I know where I'm really at - 30 years seems pretty old for something like that and they're only $10 or so. I also wonder how much water pressure is considered "safe". I replaced all the crawlspace plumbing with crimp-ringed PEX recently, but unfortunately I had to install adapters to the polybutylene (aka. Qest) pipes that come down out of the walls from the various fixtures. Those would be a pain to upgrade, though more of a pain if they fail. So the Qest is probably the limiting thing on how much pressure is safe. Oh, and I'm pretty sure the pipes themselves are not the problem, as I was pretty careful about sizing when I replaced everything in the crawlspace with PEX. Also, a hose bib comes off the 3/4" line that goes to the kitchen (which is where I'm really noticing low flow) and that hose bib gives fine flow.
