Sandpoint keeps clogging

[BradNoble]

I purchased a warehouse outside of town that has no water. I cut a piece of concrete out in the corner, and used a post hole digger to dig down 8-10 feet. If I go deeper (12-15') I can hit thick clay. Water level is at 6-8 (visible), so the sand is collapsing into the hole. Sounds easy from here right, so I pushed a sand point in 3-4 feet below the water level and installed a shallow well pump, and no water.... The sand is clogging the point immediately. The Sandpoint is from amazon and doesn't have a filter size on it, but guessing it is the usual 80 gauze. Should I go with a plastic point with sliced openings .010", a 60 gauze metal sandpoint, or open to any suggestions. I'm worried if I go with the 60, then the sand will clog my pump. This water will be used to rinse hands off, maybe put a toilet in, etc... not drinking it. Its just frustrating having water visible, but not able to pump it up.

Sand itself makes a good filter as water will flow right through it. If sand is clogging the screen the screen is probably too large.

Could slow the flow down by installing a globe valve piped in the bottom out the top on pumps discharge then the pump wouldn't suck as hard. Using it for hand washing measure flow with a stop or second hand watch and a 5 gallon bucket.

Your pump is sucking on the 2-inch pipe, right?

In operation, there would be a spring-loaded check valve at the top of the 2-inch pipe.

It would be interesting to put a combination vacuum+pressure gauge at the input of the pump to see if the pump was developing enough suction.

If you stop pumping or it's very little possibility of burning up the pump seal. Water lubes and cools the seal.
