You are testing flow essentially at open discharge (low pressure). Per the pump specs, it is capable of at least 25 gpm at very low discharge pressure. You also report only slight drawdown from static level. That indicates the surrounding strata is not the limiting factor. The above narrows the problem down to the suction system being too rerstrictive or the pump having an internal problem. That could be clogging with mineral buildup, more in the nonmoving components, or a damaged/very worn impeller. I will hazard a guess that the problem is in the suction and the pump is okay. Is the pump noisy when running, sounding like gravel is going through? That indicates cavitation, which is forming and collapsing bubbles of water vapor. That in turn means starving for water, and it is damaging the pump over time. If it's at all practical, you could set up a temporary, short , larger suction to a container of some sort to test the pump itself. I have not worked with this shallow well stuff, so I'm not up on the details of jet pumps, well points, etc. (Here, we tend to use submersibles in deeper wells and centrifugals out of surface water or tanks.) However, one rule of thumb calls for a suction velocity under 1.5-1.6 ft/sec in this size range. That means 2 inch pipe for the desired flow. OR a couple of suction drops, preferably in 1 1/2 inch, manifolded together close to the pump. It is normal to use a suction a couple of sizes larger than the pump inlet, bushing down close to the pump. One last thing, suctions need to be plumbed so entrained air is not trapped in a high section before the pump inlet. That is, rising or level all the way to pump. Assuming suction restriction is the problem, the question is whether to enlarge the entire single existing suction or add at least one more drop. Perhaps other informed folk will weigh in, always glad to learn something new.

Flow rate is ~15 GPM (just over 19 seconds to fill a 5 gal. bucket) 1" line There will be two of us living in the home, but it is lakefront, so we will have visitors on the weekends most of the summer. There are 3.5 baths, 2 with tubs (one is a whirlpool, seldom used), 3 showers (2 with multiple heads), 2 dishwashers. I figure normally one will be used at a time (showers or dishwasher), but would like capacity for 2. I was thinking a Fleck 7000SXT Electronic at 40,000 grain capacity, with gravel underbed, Fleck top basket, and 10% crosslinked resin (or 8% USA resin). I am confused by all of the options for iron filtration, and the sulfur smell is pretty strong. I am thinking 2-2.5 cu.ft. MangOx for the iron, but I am seeing mixed opinions on if that can handle the H2S. This post was edited by jonw9 on Thu, Aug 22, 13 at 9:49

Casey, thanks for doing the speed test! I googled Chicago Faucets pot fillers ... they look like they're commercial quality and very reasonably priced. Unfortunately, I need a deck mounted filler (exterior wall), and they don't seem to make one.

The Hansgrohe 27143001 Croma Green Tub/Shower Showerpipe has a 5.0 gpm flow rate for the tub spout, a 2.0 gpm flow rate for the shower head, and a 1.85 gpm flow rate for the hand shower. The showerpipe is an all-in-one system and requires only the addition of the Hansgrohe 16181181 Basic Set that attaches to the pipes inside the wall and to which the showerpipe is connected outside the wall.
