    Did I waste my time? Pumping from a pond

    Hmm, looking at the deep well pumps, it appears I don't have many GPM options. I supposed I'll have to buy a 5 GPM and use a gate valve to simulate head to get the optimum GPM for my well.

    Did I waste my time? Pumping from a pond

    Ok, I totally misunderstood your test. I thougth I was trying to get a GPM where there was no draw down at all, but I guess there is always some. If I'm going to use this well to supplement my pond level, there will be a sumbmersible in it running 24/7, at whatever GPM the well can...

    Did I waste my time? Pumping from a pond

    Yep, I understand the curve. But maybe I'm still confused. My plan was to buy a cheap submersible, use your method for measuring the GPM. If I understood it correctly, I was going to put the pump with open air line in about 4 ft, hit it with a small compressor and the gauge would have a...

    Did I waste my time? Pumping from a pond

    Ok, makes sense. However, the reason I want to measure it is to know what kind of submersible to buy ;) I assume I can use some cheapo plastic car battery operated submersible to test with, something I know has more GPM than the well would have?

    He hit the bedrock at 18 ft, went into that 1 ft with the casing, the rest of the depth is just rock. That is how it is done in my area he said. I live very close to Lake Ontario. I guess after you get through the bedrock, you hit salt deposits. ~45' is as far as they will go in that area...

    Did I waste my time? Pumping from a pond

    Well, after all that BS with the crappy Chinese made sand point junk, I had a well dug last Oct. They went down 46 feet with a 19 ft long 6 in casing and got real nice water, he was afraid to go any further because in that area if you go any deeper you hit salt. At this moment in time, the...

    Did I waste my time? Pumping from a pond

    Well, I don’t believe this to be the case in my situation, as I accounted for this when I dug my ponds. The local water conservation specialist from the DEC informed me that the water table in the spring is 18” below grade, and at the driest time of year it is usually at ~68” below grade. When...

    Did I waste my time? Pumping from a pond

    Then why can I get 3 GPM with the small footvalve, and I get nothing with the sandpoint? I guess I don't understand why the casing replenishes with the footvalve, and not the sandpoint. I didn't expect that to happen...

    Did I waste my time? Pumping from a pond

    I decided to try and salvage the well screen from the Northern Tool well point, and use it in my existing 17' deep well to try to filter out the sand. Existing well is 17' deep 4" PVC casing, and a pitcher pump with a foot valve 14' deep...

    Did I waste my time? Pumping from a pond

    The washdown method looks interesting, but not sure what I'd do when I want to penetrate the shale. Also, I do not have running water at my lot. The steel bar down the center of the casing and driving the well point directly seems like a great idea. However, I still don't trust the crappy...

    Did I waste my time? Pumping from a pond

    Local well drillers are like $3000-$4000. I just don't need a well that badly I guess. And NO, the person who is guessing "deep well drilled" is incorrect. I talked to the DEC and local geotechnical services. In my area, I don't need a deep well drilled, the water table never goes below 12...

    Did I waste my time? Pumping from a pond

    So I decided to try a driven well point this time. I figured since most of the driving would be through sandy loam soil it should go pretty easy. I bought the 2" well points form Northern Tool and Equip. http://www.northerntool.com/shop/tools/product_200321309_200321309 Some drive couplings...

    Did I waste my time? Pumping from a pond

    I talked to a local geotechnical firm that has records of core samples near my property. They tell me the glacial till layer stops between 18-20 ft and then there is shale rock. Would the driven wellpoints I try, be better suited in that shale layer as opposed to the silty clay above the...

    Did I waste my time? Pumping from a pond

    I pumped by hand, and contunied to do so until I could hear the foot valve sucking air. I decreased the rate until I could continually pump for 20-30 minutes without hearing the sucking noise. I then placed a 5 gallon bucket under the pitcher pump and continued at that rate. I got 3 gallons...

    Did I waste my time? Pumping from a pond

    "dry time" of the year is only 1-2 months away for me, so it's close at hand. Up here, fall is kind of a rainy season, by Oct/Nov, the ponds are usually almost topped off again by runnoff. So May to Aug is when I really need to use this well, which is NOW, this time of year. And currently it...

    Did I waste my time? Pumping from a pond

    I have some ponds located in Western New York. Starting in about May, the water in the ponds starts to drop due to evaporation, and probably some wicking into the banks, and also maybe due to the water table dropping. By about August, the ponds are generally 18-24 in below the normal level at...
