How complicated is it to install a pool overflow drain. From what I have seen, you install a little grate next to the skimmer and run a pipe from that to the curb where the pop up drain will be. I am only doing this because my HOA requires it. My plumber is saying it is an additional 2k, but I already have existing French drains with a pop up at the street as well. Would it really be 2k? Or is it as simple as either running a pipe to the curb or tapping into the existing lines from the French drain?
