[QUOTE="BryanDP, post: 4062771, member: 1111"] Thanks everyone for your input. One issue I know of is that we did undersize the supply line from the pump to the house (the one with the 40 foot distance and about 10-15 foot rise) but it's not in the cards right now to dig it up and redo it. What's frustrating is the we *sometimes* have adequate water pressure so I know the infrastructure is capable of doing what we need: it just fluctuates too much. I can sit at the pump gauge and watch it happen. I starts up at 50 psi and holds it for a minute or so then starts falling, down to 30 until the pump kicks on and replenishes the pressure. The 50 psi is a decent shower. The 30 sucks. If I just had 50 psi of constant pressure somehow I would be totally happy. After I posted last night I ran across a couple of articles that listed a "constant flow system" as one option to resolving our issue. I did some searches on Amazon and on the web in general and most of what came up were little utility pumps for RVs and so forth. Most could deliver "up to 45 psi" so I'm doubtful that would be enough to push it up the hill through my 3/4" pipe. I then found this: [URL unfurl="true"]http://www.burcam.com/en/products?view=details&mainsection_id=100&section_id=20&cat_id=220&sku=506532SS[/URL] It provides up to 65 psi constant pressure, specifically stating that no pressure tank or pressure switch is needed.
