Discovered today that my skimmer line flex pipe is pinched/collapsed. I've had the same issue last year on a return jet but it was able to be repaired without cutting into the patio concrete. Question now is do I replace ALL my flex pipe or is there another alternative. In gas lines they are able to pull a slightly smaller diameter pipe through a broken one for repairs under ground. Is there a way to do this with something like Pex? Would be able to pull it back through the jets and skimmer line and avoid ripping up a large section of my patio.
