Has anybody ever pumped water out of a 1.5" diameter wellpoint access pipe? If so, can you recommend a pump? The access pipe is about 14' deep and has a curve. It is located adjacent to my pool. I am concerned about being able to suck over 10' of air before the pump actually starts to pull in water. Also, I am concerned about sediment/dirt getting past whatever filter the pump comes with. Any advice would be greatly appreciated.
