Are there pool supply line repair methods that would not require ripping out a section of the 4' wide coolcrete that surrounds the pool?
I've done this many times...and all you have to do is dig under
the deck till you get to the wall. it's not the easiest way but the
only way without cutting up the crete. dig under and crawl into and
clean it out around the pipe(don't forget to plug the return inlets
and close your filter multi port)it's norm. the 90 degree fitting
that's coming out of the return .you have to cut the pipe back
about a foot and because you can't just go right back in you have
to use 3 elbows and make a bend in the pipe..use tape on the return
and a good pipe dope(perm a seal )use lots of glue and make sure
you got it good and dry...it's not the most fun job but it should
work for you...good luck..
