I've got an 18X36 IG Vinyl pool. I'm tearing up the concrete deck and replacing it with pavers. While doing that, I'm going to replace all the piping and the skimmer due to leaks and it being 30 years old.
My pool currently has a return in the deep end, another in the shallow, and there's a third return line in the center to left of the skimmer that appears to be closed. When I say closed I mean that there's the standard round white ring screwed in to the pool for the return, however in the center, rather than there being a hole for the pipe/jet, the liner is there instead. There's also a return line pipe coming out of the ground near the pump that is plugged up. So it seems that there must have been a leak years ago and they plugged the line. When it came time to replace the liner, they just put the liner right over the return, but still screwed on the white ring.
So, now for my question...I figure I might as well reinstate this return line since I'm digging up the deck. Can this be done with the liner already there? Any instructions on how I'd do it (i.e. do I just cut out the part of the liner that's over the center of the ring)?
