120v submersible pump for a 2" well casing

[JCoastie]

never heard of an air lift pump before. Saw a few videos on youtube and that looks like a good emergency solution.
Would I need to run a smaller water line, like a 1.25 or so along with a 1/2 or 3/4 air line, or would the 2" well casing be fine with a 1/2 or 3/4 air line?

Never tried constructing a small air powered water lift pump but I did make a 4" one for mucking out my well. I used standard 1/4" air hose to provide the air. I blew out a lot of sand and debris.

Well, it depends a bit on how high the yield is on your well, and how big your compressor is. If they are both small, yes, I think you would benefit from running a smaller pipe, but I would try it out first and then decide. As I wrote earlier, you have to "tune" these pumps a bit.

All the best,

If it’s for emergency purposes only consider one of the original hand pumps that have a sucker rod and a down hole pump.

Just as the initial test, do I need 2 pipes, one for water and one for air, or can I just pump air down the well and water will come up? Seems like the air would just bubble out and not force water up with just an air pipe and nothing else?

Not great news on the well front, I measured it this morning.
Water is at 53 feet
End of well is 66 feet

Not much distance between the water level and bottom. On a positive note, it seems clean at the bottom, and it hasn't been used in about 15 years.

If you use a separate water pipe, then you would need a port or an elbow to get the air into the water pipe. Ideally, the open end of the air pipe is a few feet up from the bottom of your water pipe, so it stays "primed", and the bottom of the water pipe is a few feet up from the bottom of the well. You could put a hole in the side of the water pipe and stuff the air line in, or you could rig up an elbow. My concern is the small diameter casing doesn't give lots of room, and you don't want anything to snag.

Does that help?

All the best,

Peter

Probably not enough volume for an air/water type pump. An old fashioned pitcher pump just might be the way to go.

A "pitcher pump" will not even come close to sucking water up from 53'.
An old fashioned rod pump will do that though.
I have a functioning rod pump with static water level level at 36'

There are manual pumps that will pump down to 100'.
