My neighbor used to "jet down" a shallow well point in the sand. I can't remember exactly how he did it and he is gone now. Somehow he used water to flush out a hole.
He used to work construction for utilities and he learned this at work.
sandbur, I am very familiar with the method you speak of, I mentioned it in a sand point thread on the other forum a year or so back. I had a buddy who's dad owned a well drilling business when I was a kid and I helped him and his dad put in many sand points like this. It is the easiest method I have ever seen, but I cannot find any information on it online. We called it "blowing a sand point". What we did was used 4" or 6" PVC as a "well casing" and then inserted the sand point to the bottom of the PVC after it was at the proper depth. Basically you need a water supply like a portable stock tank with a pump and some garden hose and a large industrial pull behind air compressor with a bunch of hose, like the ones construction crews rent for job sites. Dig(or vacuum) a starter hole about 3' to 4' deep with a post hole digger, run the water hose and the compressor hose into the full length of PVC, stand the 20' length of PVC and hoses up in the hole. At that point fill the PVC up with a bunch of water(you have to be watchful, as at a certain point it just starts to overflow the starter hole), once the pipe is as full as possible with water, you just turn on the valve on the compressor and through some combination of hydraulic/pneumatic forces that I still do not understand, it quite literally sucks the PVC right into the ground, all you have to do is wiggle it a bit as it is going in and guide it so it stays perpendicular to the ground. Once you get the first length of PVC into the ground with about 2' to spare, pull the hoses and glue on your PVC connector to the pipe in the ground, while it is setting, run the hoses into the next section of PVC, just insert the new section of PVC into the coupler and glue it in place. Then just start the whole "blowing" process over again for the second section of pipe. The farthest we ever "blew" in a point was 47', 2 - 20' sections and a 10' piece that we couldn't get to go in any farther than 7'. Buddies dad had a way to know when we hit water, but I can't remember what it was? He would then insert the well point and piping into the PVC "casing" and backfill the bottom 6' or 8' of the PVC with pea gravel to help keep it from clogging with smaller, loose particulate. Then just cap the top of the "casing" and run the point up to the above grade piping. I really wish I could find some info on it, maybe with video. I thought it was BS too until I helped them the first time. It actually takes longer to dink around with the equipment than to get the point into the ground. Also, as a side note, the guys "helping" the pipe into the ground get extremely wet and a bit muddy, the water and sand come out the top of the pipe like a geyser, it has to go somewhere. Great job in the July heat for some high school kids looking to make a buck.
