I bet it is not that much less. You still bump up against physics. Yeah, and I can't afford a learning curve.. You can do some rough calculations based on the cu/ft per min of the compressor at 100 PSI (roughly 200' head) and convert that to gpm of the water at 8 times that but I doubt it actually works that efficiently. This would be the max possible. That sounds about right, the video I saw had a 200 foot well with 85 psi, and it was glugging a cup and a half glug, every few seconds... the guy said it was doing about 4 gpm.. Most of the vids I have seen look pretty stable as to the concept. The flow is not steady, and I am sure it's noisy, but it does seem to work with very simple setup. Another concern is water level in the well, there needs to be a few feet of pipe below the air inlet on the pipe for it to work right. At the same time I am still working on getting that old pipe out. Got the Tee you recommended on today, and will try to pull the cap when I get home tonight and can build a staging to hold the pipe and tee.... When I hand bored a 43' well at my last house, I used a couple 2x4's with a hinge and a hole drilled the size of the pipe to clamp around the pipe as I pulled the 10' sections. But I had a pipe flange connecting the sections while drilling. So maybe you could modify, and wrap a length of chain around the pipe and let the chain rest against the wood while splitting the pipes. |

I have to decide soon, need to get this thing out. Hey, anybody know if I am gonna' need a permit to change the pump? |

If you have air, it might be worth trying to get as much water out of that pipe as possible., I am not sure about where the water comes out. Down here the water would come up the pipe in your picture. It doesn't freeze here. If you are coming out 4' below grade, you will have to dig that out and cut it before you can do anything Yeah, that's what I figured... that's gonna' be a bitch. |

Where did the pipe coming out the top go? I don't know yet... There is a chance that was the output. You could try dropping a line down it and see if it goes to the pump. I am reasonably sure it's attached to the main line but it must be closed off at the tee. Being in CT the one thing I do know is I am going to find a pipe at least 4 feet down going the 35 foot run to the basement where it comes through the foundation. If it were open, the pressure from the pump would shoot the water out of the ground there instead of pumping up the pressure tank. But again, I don't doubt it's connected. |

This would be the max possible. I doubt it is more efficient than a submersible. Heat loss in compressing air, the loss in pumping, etc. a 3/4 horse pump these days is fairly efficient. I run a 1.5 and a 1 horse pump on my pool. 4 hours on the big pump and 2 hours on the smaller booster for the pool sweep and my electric bill is only about $50 more than not running the pumps. And the gold dredgers use these, but the head is only a few feet, not a 100+ For their air pumps. |
