Hello, All! Thanks in advance for your advice!

I am planning to convert a 2-inch pvc well from air lift to a packer jet system. My well is 71.5ft deep and water is at 45.5ft. I do not know how much water the well produces and do not need it to be fast as I pump to above-ground storage. For now, I will just be happy just to lift water to my above-ground 1800-gallon storage tank. I am concerned, for perhaps no reason, that the well may not be a fast producer so the idea of a tailpipe resonates with me. I understand that I will need to restrict output flow somewhat with a ball-valve in order to prevent loosing prime. Presumably I will have some ability to restrict output in this way as well.

I plan to use a 1/2hp Goulds J5 on a AWJ2 packer adapter with a FP2B-31 packer and 1-1/4" schedule-80 inlet pipe with the special turned couplings. The packer would be set at 50.5ft which, according to the Goulds documentation, should yield ~7.6GPM. I don't have room in the bottom of the well for the full 34ft tailpipe but I could drop a 15-ft tailpipe which would cut production 30% before sucking air. That puts the inlet about 6ft above the bottom of the well.

Does this sould like a reasonable plan? Would you do it differently? Should I install a foot valve at the bottom of the tailpipe or just a strainer? I like the fact that this also puts me lower in case the water level drops but will it still work if the static water level gets below the packer? 15-years ago I was calling the static water level 30ft, so either I measured wrong back then, do not recall correctly, or the static level may be dropping 1ft/year. Lastly, does anyone know what size tailpipe fitting is on that FP2B-31 packer?

Thanks again!

I would not run a tail pipe that close to the bottom. If it doesn't suck up debris now, it will when the sediment in the well fills in a couple more inches. Just put a ball valve on the discharge of the pump as you can restrict it to as little as 1 GPM without hurting the pump. 1 GPM is 1440 gallons a day. Just don't want it sucking air.

Instead of a ball valve for flow restrictor a globe valve will maintain a consistent flow. In the bottom out the top. Might also think about a timer for the pump. X run time and X off time
If you think the pump would run dry and eat the shaft seal.

Sorry for the slow reply, I didn't get a reply notification via email.

Thanks for the advice. It didn't work out as the the packer would not hold prime below 22ft. Presumably there is a problem with my well casing at 22ft.

Hey, wait a minute.
