New to here, sorry if this is question has been asked before, but could not find any info in searching. I have a 15 x 30 vinyl sport pool with a main drain and 2 skimmers, DE filter and whisperflow pump. There is a crack or broken inlet line from one of the skimmers. Filter gets full of red dirt (Oklahoma) and sand when this skimmer is on. So much sand got sucked in that it damaged the DE filter grid fabric. Have done many test and have determined 100% that there is a crack or broken line from this skimmer. There is not a local company that will line the pipe. I really don't want to dig up the line, pour new concrete, etc. Has anyone ever tried lining the pipe themselves using with a vinyl hose similar to the thin flex rollup hose like the hose used for waste/flushing. My idea is to snake a wire from the skimmer to the shutoff valve, and pull the lubricated flex hose through, much like an electrician pulls wire thru conduit, then secure the hose to the pipe at the skimmer end. the overall repair would be similar to this product, but with using the standard vinyl hose. http://www.flow-liner.com/swimming_pool ... epair.html. Any thoughts? Also, has anyone used flow-liner?
