Hello everyone!
Hoping to get some advice on my first attempt at a driven point well in a sandy area. I bored a hole down until I hit water and couldn’t dig anymore due to the hole collapsing and then drove my point down about another 5’ bellow that point. I’m able to draw up water but the suction is quite hard in the hand pump and it’s pulling up small amounts of sandy water. Do you think I should drive my point deeper? Keep pumping water out until the sediment is run through and it’s clean? Any advice is welcomed as I’m a total beginner with this.
Here is a link to a YouTube video showing the water I’m able to pump up.

I don't think you have much water in the pipe and probably need to drive it deeper.
Tie a nut, or fishing sinker to the end of a string and drop it down the pipe until you hit bottom. Then pull it up and see how much of the string is wet. You want to keep driving until the last several feet of pipe is into the water source, but not below it.
No matter what you do, you're going to have to pump a ton of silty mud out until it clears up, it just takes time. If you have access to a hose and another water source you can backflush the well and that will speed it up a bit.

As jhp said, plus in the other thread about driving sandpoint it was mentioned that if you can hook an air line to the pipe this will allow you to clear the sandpoint screen and possibly create a better pocket around the point to draw water from.
Might want to Google this to see how this is done and if it applies.

As a farmer friend told me,"driving a sandpoint is just the beginning".

Thanks everyone! I’ll keep driving it down. Any tips on knowing how to not go “too deep�
The point should in theory be fully buried in the water line at this point. No idea how deep that layer of water is though!

Seems I remember reading something about going down until you hit water, mark it.
Go incrementally deeper until the water slows, then drawing back a bit.
And that the point typically needs to be at least 10' below where you start to get water or you dont have enough volume in pipe for use and recovery.
Iirc!
