My inground pool seems to have two leaks - one in each return line (vinyl liner pool). Given I have a 3ft cement deck all around the pool, the pool technician who found the leak suggested installing new return lines given the current lines are about 30 years old. Instead of breaking the cement decking to pass new lines, he suggested digging a 1 foot deep path just outside the cement deck in the grass and only breaking the cement when connecting the lines to the jet in the pool. I thought 1 foot was not enough given I am in Canada, but he said given I empty my lines in the winter, it didn't matter that they were only 1 foot deep instead of the usual 3ft or so. I was curious to know if anyone sees any issues with this solution? It's definately much more cost effective and I like the idea of having my return lines in a spot that is easier to access.
Second question - he is going to run a line to each jet, connect them to a T and from the T, run a line to the machine (all underground). I was thinking of running each jet individually to the machines, with the T placed in an accessible spot at the machines. Any issue in doing this?
Thanks for the help!
