Well Sand Point

I am going to be sinking a new sand point this weekend. The existing sand point quit working.
I can pour water down the old pipe and it will go down very slowly. If my thinking is correct, where it stops should be the top of the water table. When I drive the new point, am I supposed to just stop once the top of the point is under water? The old well was hooked up with some flexible pipe and has some splices in it so I was going to leave it down and just relocate the new one closer to the house so I can just hard  pipe it all of the way to the pump. My thinking is to measure the old one and sink the new one to the same depth. But how do I know when I hit the optimal depth? I have seen videos on YouTube that say, put water in the pipe and it should exit as fast as I put it in.

Welcome to the forum.  Sorry to hear you are having well problems.  I am sorry to hear that.

I wish you the best.

Most sand points I've seen have a 3 or 4 foot screen area where the water comes in.  That all needs to be under water.  So I'd aim to have the top of the screened part be under the water table by at least a couple feet.  I don't know what the official recommendation is though.

I don’t know if anything is official with a standpoint.   I have had people tell me to be happy when I hit water. Others have told me to take it down a few more feet. And others have told me to drive through the first vein of water until the second one is hit ( sounds pretty optimistic). My one experience with driving a sandpoint involved 3 of us taking turns for the better part of a day.   That was in the mid 80’s,so I don’t remember many specifics.
