    OK...here's the history...I put an 1 1/4" sand point in 7 years ago...it ran fine until this year. I suddenly had no capacity for my sprinklers. When I ran a garden hose down it, the well just takes the city water and it never comes up to the top of the pipe. It would show 6 feet of water static though in the 16 foot well...
    I jacked out the old point and it was scaled and plugged up for 95% of it...the top 3" (36" well point) showed a lot of rust, leading me to believe that it was catching air at the top...
    I drove a new point today, and it is 18'6"...I am showing 6.5' of static water in the well. If I run the garden hose down it, the water never comes to the top of the pipe. It just flows and flows down the well.
    I went though one layer of clay...Could my point be plugged? I would think the water wouldn't go down from the top if it was...
    Do I need to go deeper to just on top another layer of clay?
    How can I have 6-7 feet static water in the well, yet flow city water down it all day without it coming to the top? My screen cant be plugged if I can do this right?
    My neighbour has experienced problems too this year...The city is doing some road work / drainage...Maybe they dropped the water bearing level?

    Please help...I am out of gas and money!

    Regards,

    If the well is taking water then the point is not clogged. I would guess you have a small air leak at one of the couplings or before the pipe gets to the pump.

    Thanks for the reply...
    I tightened really well all the way down and used ample pipe sealant...Do you think I need to develop the well with air or make a bailer?

    A hand pump would work better and would let you know if you have a leak.

    "Well"...(sorry) I figured it out...It seems that I snapped my suction pipe off at a coupling...Good news, it's 4 feet down...I dug down to it and will manually rethread tomorrow...I have no idea how I managed to do this though, I was using a 14" pipe wrench and was being cautious as I have snapped one before...I guess too many Wheaties...Hopefully that's the only broken thread section...Must be a bad batch of pipe, since its the 2nd time...maybe someone threaded too deeply?
    Anyway, explains why I had 7 feet static but couldn't draw, and it would take all the city water I could give it...
    Better not be snapped anywhere else!!!

    Keep you posted....

    OK update...dug down and rejoined suction pipe. I can slowly fill the suction pipe to the top with city water but it drops down fast when I stop filling...
    I have a water faucet tap attached to the top of my suction pipe. When I supplement the suction side with town water, my pump will pump, but when I turn it off fully, the pump dies...
    When I open the water tap on suction side after I shut off the pump, there is a lot of suction at the tap...It is pulling some lift...Just cant get it to catch enough to be self sufficient..
    I didn't blow my pipe with air, but like I said, the town water flows quickly down the well, telling me the tip is not plugged...
    Any suggestions apart from dropping another tip?

    Frustrated badly, please help...
