Is this steel casing or pvc? It's not the pipe that causes clearance issues, it's the couplings. All 2" wells with packers are designed to be used with 1.25" pipe. You have to have special thin collars to go into the 2".
It is a steel casing. I bought 1 1/4 inch belled 20ft sections. The widest part of the belled end measured 1 7/8, that only give 1/8 clearence for water to go back to the ejector. Will this work?
