I suggest going with a 60 mesh point ANything finer will clog up. Also use two inch well pipe. It comes in five foot length. If you know how to witch you should also be able to tell how deep the water vein is. A pitcher pump will pull about 22-24ft. If you hit a vein at that depth you will usually get a "head" of about 6 feet of water up the pipe. Use drive couplings and tighten the the lengths of pipe as tight as you can get them with 36" pipe wrench, plus a little more. Use teflon pipe tape for the joints. You'll know you're in the vein when you can't fill up the pipe no matter how fast you pour water into it. If need be I can take pictures of the trip pod, driver set up at a well I'm helping to drive right now and send them to you
