    Default New Shallow Well Can't Get Primed

    Hello all. New to the forum and new to shallow wells. I live in a very sandy area (all sand). The water table is ~9' below grade (lower in the summer). I pounded 2" galv. pipe with a sandpoint down 17' until it wouldn't move any more. I think I'm on bedrock based on info from a local driller. To blow the well out (clean the sandpoint) I rigged up a spicket on the top of the pipe so I could flush the well out with water pressure from my city water supply. I have standing water in the pipe at 9'. I know this b/c I sucked all the water out of the pipe, waited a while then measured the standing water using a string and weight. I attached a rudimentary diagram of the well and the pump so you can see what I set up. Basically, I put a pvc elbow on the top of the galvanized pipe, reduced from 2" to 1 1/2". That takes me through my foundation, then there's a priming t, a check valve, a 1 1/2" to 1 1/4" reducer and the jet pump. The horizontal distance between the elbow on top of the well pipe and the jet pump is only ~10'. My problem is I can't get the jet pump primed. I pour water in the priming t inside the foundation and in the priming t on top of the jet pump and cycle it. Have done this MANY times. No luck. My question is ... what could be wrong? Should I have a check valve closer to the top of the well or?

    Thanks in advance for your help.

    Forgot the attachment. Here it is. BTW... wondering if I just need a bigger pump. I have a 1/2 horse with a 1 1/4" suction. Is that enough horse to pull from a 2" well pipe?

    When your priming the pump your not getting any water into the pump. The check valve needs to be closer to the well with the priming tee between the pump and the check valve.

    Hello again. I installed a check valve right after the elbow on top of the well. Still doing the same thing. It seems like it's just not able to pull any volume of water. I know my check valve is facing the right way (arrow pointing towards pump). I'm getting some water from the well. I know this because the check valve is cold to the touch and the little bit of water that is coming out is brown. The well seems to take water pretty fast. I know this because when I pour water down the pipe, it recedes back to static water level pretty quickly. I know I don't have any air leaks on the supply side because when I unscrew the cap near the pump on my priming T, I can hear and feel the vacuum suction being released. Do you think think I just need a bigger pump? I'm trying to pull water up a 2" diameter pipe and the intake on the pump is only 1 1/4". It's 1/2 horse. Thanks again for your help.

    You don't know if the well makes any water. It might not make any.

    Thanks for the reply. There is standing water in the well at 9' below grade which is 5' below the top of my well pipe (I dug a 4' hole to get below the frost line). When I use a utility pump, I can pump all the water out of the well and it will refill back to 9' below grade in a few minutes. Also my sump in my basement pumps out a 30 gallon basin about every 5 minutes. I'm not sure if these things mean the well can make water but I was assuming they did. Is it possible given these things that the well is not capable of making water?

    I am no expert here, but I believe that was backwards. The idea is to drive the point down until it contains water, then use a pitcher pump (or a utility pump) to develop the well by pulling from it until it runs clear.

    @ rednech, I do hope that if you choose not to use those two wells you will properly abandon them as outlined in the Ct Water Well Regulations 25-128-57.

    Spoken like a true professional more interested in proving that you shouldn't do it yourself and that you should hire a professional. This is a do it yourself forum. If you're not interested in helping then don't waste people's time. I got the wells working myself and am planning on using them. So your regulation doesn't apply.

    You can do it yourself but I'm betting you did it without a permit. If you give us your location we can contact you building department for you.
