Does anyone have any experience with pool plumbing fix products that avoid having to dig up the plumbing lines? A couple that I've seen from Googling are Pipefuze (epoxy kit) and Pipes Down Under (Pipe insert kit). They are expensive, but their cost is much less than demolishing a 3 year old stamped conc pool deck, and having the repair for it never look the same.

Any help would be greatly appreciated!
