ok...here is the problem. Pounding a 1 1/4 well pipe and sand point. I need to get down to about 20'. After hitting water the FIRST time, I realized that the pipe had split at the threads that had not gone into the coupling. I pulled out 10' of pipe and chalked it up to learning. I started over and got to the same depth (no rocks...just nice sand) and the SAME thing happened. It seems strange to me that the threads of the pipe do not totally twist into the coupling...there is plenty of space. What I fear is happening is the threads are taking all of the beating inside of the coupling. Shouldn't the two pipes in the coupling meet togather in the middle to help "cushion" the blows and transferr the pounding down to the sand point? I screwed teh pipes as far as they would go into the couplings! The exposed threads outside of the coupling are the weak point. I am using a 50 pound post driver over the top of the pipe to drive the whole thing. I was not pouring water into the pipe to soften the sand, so I will do that; but otherwise...what the heck am I doing wrong? Lighten up on the pounding?
