    sandpoint depth question

    Speed, I was reading some old posts and i came across one and you stated if you cant pull up water with a pitcher pump a jet pump wont work either.

    I was at the lake house last July and I hooked up a hand pump after I rebuilt the leathers in it. I primed it and pumped for 10 minutes. I felt resistance but it wouldnt surface.

    My neighbor came by with a piece of lead on a string. I took off the hand pump he dropped the lead and the water was 65 feet down if Im not mistaken.

    This pipe is about 15 feet away from the main pipe connected to the jet pump. Back in the 80s we used to have the hand pump connected to it. Is 65 feet too deep for a saindpoint well? If so what are my options? Whats the ballpark range to have someone come out and drill a deeper well?

    Rancher would have a better idea of the costs in AZ than I would.

    A shallow well pump of any kind can only lift water 25 feet vertically. In the scientific world that number is 32 feet, but in the real world 25 feet is the max. A deep well jet pump can go as deep as 150 foot with the right pump and the jet in the well at the water level. You will need at least a two inch well to make this work. They don't make jets for anything smaller.

    I have never seen a driven well deeper than 35 feet. That is in Michigan where there are a lot of them. Here in Florida, my experience in the two county area I am familiar, 5' to 25' is standard.

    15 years ago it was $15/foot for steel, $12 for PVC, I think it's around $20 now, depends on how hungry they are.

    But I think the well he is talking about is in Wisconsin

    Oh, if that's the case, I don't have any idea there either. For some reason they seem to drill all 6" wells there. I'm not sure why. Michigan was 4" for steel and 5" for PVC. But the prices I'm sure have changed a lot.

    Sorry i should have stated location. I called a local well pro in Wi and he quoted for a 6 inch well, $24/foot and $1K to screen it. I told him about the orangish water we used to get with the sandpoint and he told me that its pretty much the norm in that area, sandpoint or deep well. Man its like a tennis match, I just keep going back and forth between rainwater and well water!

    For my money, it would be well water. Nobody can screw with that yet.

    The one they drilled me was a 7" steel well cased all the way down... why 7" I dunno, try to find a well seal for a 7" well, or at least one listed in a catalog. Dean Bennett Supply came to the rescue.

    Orange is iron and/or IRB (iron related/reducing bacteria) and both are easily removed for between $700 to $1500+/-. The higher price is for IRB treatment using my inline chlorinator, mixing tank and special carbon backwased filter that I mentioned in the other thread.

    Bob, WI and MN both have a lot of well point 1.25-2" and drilled 4" wells. Most drilled wells aren't much deeper than 150'. They use 4" submersibles in the 4" and can barely get them out later. They also use alot of galvanized drop pipe too.

    The well guy told me that now its against code to drive your own sandpoint. Thats what Im probably going to do first is see I can get the driven well working first. I suppose the old sandpoint piping could be lifted with a hyd jack? Then i will drive a new one with a new screen and new galv pipe and go from there.

    The old jet pump I have in the crawl space looks like a small air compresser with the tank on the bottom. I am for sure gonna get a new one. Do jets have to be mounted directly on the tank like that? Can I use a CSV in that setup?

    Im trying to get all the info I can before I get to Wi because the house is in the boonies, and I dont think the people up there even heard of the internet.
