Hi everyone,

For the last two weekends I have been helping my brother driving a well point.  Neither one of us have any experince with driving a wellpoint.  But do have knowledge of jet pumps ect.

So far we rented a jackhammer and drove the well to 18 feet.  That is 3′ wellpoint plus 15’of pipe.  We had enough ground pressure to have about a 6-8″ fountain of water coming out of the drive cap 1/16″ hole.  Since it was my brothers well and money, all decisions were made by him.   He got advice to drive deeper so we drove another 5′ approx.  Hit somthing really solid, and had no water flow.  So now at about 23′ we pumped down water to flush and hopefully clear away some soil build up on the point.  We got advice to pull it back up.  We did get the well to flow out of the1 1/4 inch pipe again.  But never enough ground pressure to create the small fountain with the drive cap on, like we had at 18′.

So we started to pull the well back up using two handy man jacks.  Got roughly 18″ pulled up and stuff broke at connection nearest surface. Changed pipe and could move no more with handy man jacks.  Then we regrouped for the next weekend, used hydrolic jakes to pull  up, and broke joint closest to surface twice.

But did get it back up..

So currently approx. 17′ in the ground, one foot out (18 total), ball valve, 3″  nipple, check valve, then pvc (no more than 24″ w/90 going to pump.

The pump will take prime but takes 10-15 minutes.

Soil conditions are heavy, clay ect.  Located in central MN, near Detroit Lakes, MN

We are not sure what to do or change if anything, system maybe just need more flushing.  Would like input/advice.

Look forward to some input from the experts.

Thanks in advance!
