We are setting up our well. We have 30 gpm available. I am leaning towards the Vfd pump vs conventional. Although it is about $1k more. Any thoughts or experience with Vfd?
Have you ever thought of a back up hand pump installed along with your well?? I'm sure it would depend on your specifics to your location and availability of water. Bison is made in the US. They add cost but ...like I said..depends on your situation, interests n whatnot.
Using a suction pump you can only draw water up about 30 feet(or slightly less). For deeper wells, besides a submersible, you can have a jet pump above ground with the jet down in your well that will "push" the water up. I forget just how deep these will work but at least 100 feet though they do require two pipes (one with water going up and one with water going down). A submersible allows pumping water from very deep (400' +). The trouble with water is always the weight of the water. The deeper you go the more water weight you must lift.There is a limit to how far you can pull water from a well with a hand pump. I think it is between 30 and 60 feet. If your water level is below that point then you need a submersion pump that produces more pressure than the head provides.
this is true, but its a tad deeper than what your research is showing at least for a bison deep well hand pump...Its a bit of a workout..but it works at/for deeper levels.There is a limit to how far you can pull water from a well with a hand pump.

Actually that bison deep well hand pump is not "pulling up the water" but instead pushing it up. The piston is down in the water of your well, when you pull the handle up the piston fills with water and when you push the handle down the piston pushes the water up the pipe. These pumps will work down to a few hundred feet but the deeper they are the harder they pump.th

whatever works eh?? :}Actually that bison deep well hand pump is not "pulling up the water" but instead pushing it up.

That's one of the reasons some pumps are in pits. To get closer to the water table. Working on a pump in a pit IS the pits!Remember that with a shallow well pump you're measuring your max draw distance from the pump, not from the surface if the water. So if your pump is 15' above the water and you can draw to 30', you'll only have 15' to draw from...

It would not help, it's a physics thing, you can only suck that water up so far.What if a person were too put a check valve in every 30' of suction pipe ???
My brother's well is about 130' deep and the water is naturally under pressure, it comes up to about 45' deep or so. He uses a shallow jet pump and it works quite well. I wouldn't hesitate to use one if the conditions were right for it. But they aren't cheap and they don't last forever...but then no well pump does. It's almost imperative to have a replacement pump on hand, because they never go out at 9AM on a nice sunny day. It's always after dark, on a weekend, during a blizzard, when you can't get to the store for a replacement. At least that's my experience.It would not help, it's a physics thing, you can only suck that water up so far.
There are options. There are special jets that use the normal well casing along with a smaller drop pipe so you can then push the water up a greater distance. These jets are available for 1-1/4" and 2" pipe. For larger than 2" well casings you can use the more standard 2-pipe jet system or a submersible pump. Anything over 30' is a deep well and requires a deep well pump of some kind.
