Hello all. I have a Pentair skimmer with one hole at the bottom. If I look deeper into the bottom hole I see two others - one coming from the main drain and one going to my pump. The holes beyond the bottom skimmer hole are inaccessable. I've trying to do research on this and it appears that a little swinging door that I could have used to cover up the main drain hole was not installed.
I've been using a vacuum that doesn't require suction (Aquabot Turbo) but I now have a need to vacuum with a stick and vacuum head. When I plug in a vacuum hose to the skimmer hole it works for about a minute then it starts pulling water from the main drain.
I've seen references on this site for a spaceship diverter, but I don't know if that would be functional since my problem is below the single hole of the skimmer. Can anyone offer any advice? Thanks so much!
