That is a good question we get asked a lot.
A "Pitless" water well is simply a connection drilled through the side of the casing so all pipelines are underground.
A "Sleeve" is the more common method, used more for windmills or solar, the pipe exits the top of the casing and is subject to the elements.
You should go Pitless only if:
1) Your water well is out in the open in your nice front yard.
2) You live where the weather gets below freezing.
3) You want the well to be low profile see #1
3.a Pitless wells are allowed to be cut 12" minimum from ground level this is a state rule.
You should go Sleeve if:
1) You are using the well for a Windmill or Solar.
2) The water well is out in the open and grass is grown up, or is hidden. The sleeve is there for protection from getting hit.
3) The sleeve method cost quite a bit less than the pitless method.
A "Sleeve" well is required to be cemented 10' below ground to surface with a 2' Steel or PVC sleeve cemented 1' in ground and 1' above ground for protection.
A "Pitless" well is required to be cemented 21' below ground to 1' below surface for exit of pipeline.
We service New and Old water wells. From Jet-pumps to down-hole Submersibles.
Down-hole submersibles are the best way to go when setting up a new water well. They require very little to no maintenance, you set and forget them.
Jet pumps are a thing of the past, they require quite a bit of maintenance to keep running. We do service them, from new motors, to splines and pump housings.
We setup new wells with a simple manifold system, with a pressure tank, pressure switch, pressure gauge, faucet, and Ball-Valve. These can be fully customized to fit customers needs when installing.
