Anyone know water/well pumps?

[LDennis24]

What's the inside diameter of the well casing?

[birddogdad]

lift is the suction max, i think normally in feet.
head is the discharge pump can over come (should be 44# / 100 feet of depth for math to overcome.)

suction lift as stated is probably key here, you can only overcome just so much lift to get the pump "sucking". Discharge or head to the rest of the way out of the well must be overcome.

been a long time since i looked at a hand pump well (no power). There would be lift specs associated with this i would assume.

they put the pump at the bottom in a deep well hand pump, so there's no suction concerns at all.  It pushes the water up the pipe.

Just to confirm and add a little to what others have said:
- "Suction ft" is what the pump can lift from the water level below it (sometimes called upstream of the pump). This is from the water surface to the suction of the pump. You mention the well is 70 feet. If that is the water level, then you would have to place the pump at least 70 ft - 26 ft = 44 feet below grade, but you should put it deeper because you will draw the water level down during use and the pump will operate much better. I'd recommend a submersible pump as deep as you can.
- As noted previously, normal pumps can't pull more than a full vacuum (~33 feet), so you will have to drop a pump at least part way into the hole, but a submersible pump is usually used.
- "Max head ft" is the pressure the pump can produce downstream of the pump. Note that you also have to figure the depth below grade that you place the pump into this value. Using the pump you are looking at for example, if you place it 60 feet below grade, then the pump will produce 98 ft - 60 ft = 38 ft (16 psi) at grade. Unless you are just filling jugs, you probably won't be happy with that low of pressure.
- You should look into a pitless adapter for your wellhead, which would be a secure permanent pump installation that would also secure it from people throwing stupid stuff down your well. You could run your electrical to a small vault with locking lid for your use when you arrive. Use rigid metal conduit for the short piece of exposed conduit.
- As you're already aware, there is no way to completely secure it, so whatever you install, don't invest more than you're willing to lose!

Thanks guys I appreciate the info.

I’m thinking it’s 4” inside diameter.

I think your problem is going to be finding a pump to fit down inside a 4" shaft. You can always buy black polypipe and plumb it down into the bottom with a filter head on it. Then put a pump with a priming tank at the top and you prime it( meaning open the top of the pump or tank at the top and fill it with water and close it then fire the pump up and it's not having to draw water from 70 ft down. This would have to be repeated every time you started to draw water unless you could seal the casing and the pipe stayed primed all the time.

I’ve heard of a lot of property damage and theft over the years but never seen anyone take a submersible well pump!  Thats motivated.  I might try terminating the wire right at the well cap, spot weld the cap bolts on, and weld a box over the terminated end.  Bring your genny and cord with you.  Thieves could still get in but they would have to cut the lock off the top box and then cut the cap bolts completely off with decent tools for a bit of wire and a used pump.  What county is this?  You seem heavily targeted even for a remote sight with no people present.  Sounds like repeat dirtbags not random drive by. A good set of inexpensive concealed Game cameras and a chat with the sheriff may be money well spent!  Good luck

Here's a couple more creative ideas if you put in another submersible pump:

If you can cut off and seal the well head below the surface of the concrete pad and then pour a shallow concrete cover over it. 

Then you could either:

1.  drill another hole through the pad nearby and put a false well head that appears to be already robbed/empty to make it appear that the well has already been scavenged and that there is nothing good to look for. 

2.  Put a sign or etch in concrete the words: WELL DECOMMISSIONED.  for some false advertising to discourage thievery.

If you could just submerge a basic well pump with a pipe to the top of the casing you would be fine but you would want to invest in some security measures it sounds like

Kind of a simple method for priming and purging air but you can set one up a number of ways with some strategic placement of valves and a tank.

Searching (3" well pump) brought up lots of options on ebay. ~$150-$250  A cheap off-brand one might be preferred in a well where there is high risk of it being stolen.

OP was asking how to do this without power....

maybe this?  https://www.bisonpumps.com/product/standard-deep-well-pump/  one i looked at spec sheet said good to pump 300ft well water...

@birddogdad  A Bison pump will cost bout $2,500. before shipping.

just buy a cheap submersible well pump for like $100 and some poly tube. Hardwire the pump to a 120V plug. Lower the pump down the well with a rope and plug it in to generator to run it. Pull the pump and roll up the tube and wire when you leave.

As long as you are daylighting the water-flow and not trying to get pressure the above plan will work easily.
Keep it up off the bottom.
