Sand point well, need help!

I live in Manitoba Canada, and am having issues with my sand point. Here is the story.
Bought house 10 years ago with Sandpoint well, never could get it to pump.
6 years ago I bought new 30” sand point for sand.slotted screen.
Couldn’t get it going.
This bring me to last week.
I tried a new pump couldn’t get it to suck.
So I pulled the point and gave it a acid bath, not that it was needed, it was clean but to be sure I wanted it clean.
I dropped it down the casing( which is 10’ down.)
I drove it 2’ more tightening every 10 pounds.( with homemade 80lbs post driver.)
Went down smooth. And felt like sandy soil. So I connected my pitcher pump and got about 15 gal of blackish water. So I drove it down another foot. And pumped more water, it seemed somewhat clear, so I connected my check valve and pump. Primed the pump with my hand pump. And pumped water for 5-6 hours at about 1-1.5 gals per minute. I left for the evening and about an hour later it sucked air and wife shut pump down.
Now I should add there are plenty of Sandpoint in the neighborhood around 15-20’ depth.
This morning I dropped a weighted string down my 1 1/4” galv pipe and hit water with 4’ of standing water 9’ down from the surface. So I was under the impression I should have 5’ so I tried driving it down again. I got about a foot. Tried hand pump again. Nothing.
My questions are these
1- am I too low. Maybe it’s to dry to get 5’ standing water.
2- drive that sob further?

Any help would be great, I can also be reached by email.paulswiscoski11@hotmail.com

I must also add, I am a certified plumber, and none of the Sandpoint system was covered in school. Anyone I talk to says it’s an old application, and you either know what your doing or not. I like to think I’m a smart guy, but I’m losing sleep. I want cheaper water than city water. Thanks for the help gents! I have also added a picture of my setup. simple setup picture.

If I've followed correctly, you're now down about 14', is that right?  If the other wells are 15-20', You're in the ballpark, but you may be too high up for sufficient recharge.  If you've got 4' of water now, I would try to pull the sandpoint up a foot or two and see if she'll pump again.  Your point could be in an impermeable layer.  IF you pull it up and get flow again, but it peters out, you're still too high.  IF that's the case, drive another 5 feet down and try again.  If it keeps pumping, I wouldn't worry about 5 or 4' of standing water, but I suspect it'll need to go deeper.  If your neighbours are at 15' and you're 2' higher in elevation, you will likely need to go to 17'.  Geology is funny, though, so there may be big differences in water table depth within 50' of surface travel.  

I'd love to know how it goes as I'm going to try a sandpoint at my place.  My neighbour's well is at 280' but I'm going to see if I can get something close to the surface.  Might be brackish if I do find it, though.

Thanks for the reply.
So I pulled it right out.
Sent it down to the 15’ mark and started pumping black water. I’m in the process of fixing my post pounder so I can’t get deeper. But I’m gonna try and send it down a foot at a time, then check.(1- the standing water in the pipe. And 2- the amount and colour the water is.)
As I mentioned before I had water about 1-1.5 gals but driving it deeper didn’t seem to work any better.if not worse.
I guess a like taking the hard route! But just can’t seem to find the vein.

I have a question for the professionals.
Is there an actual check valve in a sand point so the water can't run back down ?
