Hello,
I have never posted here before, hopefully this is not a duplicate question but I can't see it anywhere.
I am looking for the best solution on how to pump large volumes of water out of my well at my cabin without power.
I am building an off-grid hot tub and would really rather not pump by hand...
My question is, what is the best way to do this? There are rechargeable battery water transfer pumps (here in Canada there is a Ryobi model and a Milwaukee from home depot), there are gas powered pumps, etc..
My main issue is lift, this is a "deep" well (64ft only actually) so i need lots of lift. Also the access hole into the pump to drop a hose down is 1.25 inch so nothing can be wider than that going into the pump.
Does anyone have experience with this? What is the best solution? I have never pumped water quickly out of a well, so I don't really know how it works. The amount of water we get at the bottom of the well is tons, I forget the amount of GPM we can pump but it is something ridiculously large. My question is, does this hold true for all the way up the well shaft? If my hose drops 25 feet into the well, will the water replenish at that level faster than I can pump it?
Hopefully this makes at least half sense. I have attached a picture of our pump style for reference if it makes any difference.
Thank you!

Are you wanting to have water pumped into and all around the cabin as well, like real plumbing, or are you just wanting to fill the hot tub?

Literally just fill the hot tub. Our cabin's are no plumbing, and we have enjoyed them that way for 10 years. We do have solar and water which already is quite fancy by our standards!

Is the well 64 feet deep or the static water level 64 feet?

I looked at the Ryobi 18volt water transfer pump. They claim up to 325 gallons per hour and a lift of 50 geet.
The 325 GPH is at 0 ft.The specs state at 10 ft that drops to 275 GPH. I don't know if they areeaning actual suction lift or the distance up vertically that it can push water.
The 50 ft lift number is suspicious to me. Every suction pump I have ever used has a shallow limit of 25 feet or so (at sea level at.ospheric pressure). The volume, or speed of pumping also decreases with depth. At max lift that will be a long ways short of the 425 ft.
I've seen motorized versions of pumps that look like the pictured pump. All S/S, right? Simplepump? They have deep well versions but those place the mechanism and valve way down the well hole.
So I wonder what Ryobi means by the 50 ft rating.

If I remember correct, the static water level is 12 ft.

Thanks for the Ryobi info, and I don't want to have to switch to a motorized pump as I want to keep the hand pump available. Not to mention it is probably a chunk of change.

These might work for you, but not sure how fast or how much battery you will need:

Unfortunately those fit 2" pipe, are kinda pricey and not rebuildable. I have one in two-stage that the lower pump went out/froze up. I have been able to separate the sections and am left with now a sgl-stage that I doubt can pump much from my static depth of about 26'.
Bam, it looks like your hand pump is on a pretty good sized well pipe cap. You could maybe pull the cap and drop in a decent pump, run the outlet pipe and wiring through that 'access hole' and seal up. Note you have to be able to seal it up to prevent possible contamination.

If your casing in only 1.25 it is likely just a sand point well and you won’t be putting anything inside of it easily. With a static water level of 12’ an old fashioned pitcher pump will work as long as the level doesn’t drop below 25’. The pump you post a picture of is called a “simple pump†it actually has a rod that drops down into the well at actuates a mechanical pump but it won’t fit in your well. https://simplepump.com/our-pumps/hand-operated/deep-well-pump/
I would try a pitcher pump first they are really inexpensive.

I use a solar livestock well set up. I have no batteries, nothing, just some panels and a switch, flip switch, out comes water. Now the rate is about the same as your kitchen sink, but I turn mine on and let it run all day, just to keep it clean. Its only a 1/2" pipe and it lifts water from 150 feet, but static water level is 100 feet, so that is really the lift amount.
Good example on ebay now
