I bought a home with a damaged skimmer. I used pool putty to fix it. So now that it is time to close the pool I can't really cap the equalizer line due to the putty being around the hole. I don't see me ever getting a good seal. I have read that foam rope can be used but I wanted to make sure that is a safe and viable option. I plan on using a gizzmo on the intake line and it is free of any pool putty so I should be fine on that line. Thank you!
