Our pool installer, Clearwater Pools, used TigerFlex Hose 1.5 inch for all inground plumbing. Bad choice. 13 years later, carpenter ants have perforated the hoses so that they leak like sieves.
We found a local pool contractor who was able to tunnel under the concrete deck and replace the return lines and skimmer line. No cutting, no concrete patches. While we were at it, I also had the 13 year old liner replaced.
Total cost of the project: $7,200 for a new liner, 2 return lines, bottom drain, and skimmer line re-plumbed and reconnected, plus a few hundred for a useless shoveling crew that I hired off of Craigslist.
