Hi all, I have a few follow-up questions about doing the type of renovation discussed above (to replace a concrete pool deck and the existing PVC pool plumbing): 1. Is there significant risk that if I remove the old concrete coping, I could damage the pool structure itself, such as the bond beam? 2. Is there much risk in terms of replacing the pool plumbing? For example, is there a scenario where I could need to connect the new PVC pipe to an existing fitting in the pool wall (such as one that sends water out into the pool) but be unable to connect the new pipe to that old fitting? Or can old fittings generally be removed from the pool wall and replaced? Similarly, is there much risk in terms of replumbing the pipe to the drain at the bottom of the pool? I would assume that one would need to connect the new pipe to the existing drainpipe (before the pool) because it would be impossible to send a new pipe under the pool and connect up with the drain. Thanks for any info you can provide. John
