We bought our house about 3 and a half years ago. I once opened this thing to see what was inside but ended up closing it and leaving it alone. I maintain my own pool and water from here doesn’t seem to go into the pool. I decided to open it again and cleaned it as much as I could. I have to wait for my husband to get home with his shop vac to really scrub it and clean it out.
The thing I have circled in green is what I’m asking about. It has the same cover as my 2 skimmers but it’s not a skimmer. I opened it and it has a plexiglass cover. I pulled that out and there’s a long FSI filter inside. Toward the right side, closest to the pool is a spot where you can screw something in. I have absolutely no clue what this is but I’m thinking it might be something like a vacuum to waste port. There doesn’t seem to be any pool floor cleaning system in my pool. The 2 drains in the picture are the only things on my pool floor.
