I put in a new irrigation system last spring. I hadn't hooked up the drip system last year and am attempting to do so now except the pipe that I put in last year is just slightly bigger that the fitting that I just bought. The extra pipe in the garage (same pvc pipe) still fits the new couplers. I have tried sanding but it did not help. Any suggestions? Why did the pipe swell?
