Im working on pool that has been renovated once at least.we are trying to find pipes (2 smimmers,1 polaris line,2 return lines,plus spa but we found spa pipes easy(flex)..How ever after we spent a few days jack hammering right at return line we fund that a sort of "cast" surrounds the return line pipe and brings it around the pool,right under bond beam.It is just like a plaster cast,with rim wire around it,its as old as pool.We work for anthony pools years ago and Never seen this with all digging we did....now we follow the cast pipe around steps in low end of pool,rught were euipment is and no run of this return line ! we are going to break more deck to see where it runs to equipment.
we havent yet dug up skimmers and were trying to find them in the grass as its easier,but no luck.we are worried that when we do jack hammer skimmers they might also run in this "cement cast" around pool....was this the normal back in 40,s 50,s?..there are big big rocks under neath rebar of deck right at return lins so we figured they cast the pipes to avoid digging out rocks?
also asked a rep with biscornet pools of new rochelle who are old timers since the 40,s and one rep there said it was common to do that and NOT to break the cast as its right on top of pool walls and might break integrity of pool....what to do ??? thanks anthony f.
