Hi all. I'm a brand new pool owner as of a month ago, and this website has been amazing.
My pool was built in the 80s, and the skimmer is not any sort of plastic prefabricated thing. A photo is attached, it was just poured in the shape of a square. the opening is 7" wide and 8.5" tall. A photo of the opening is here: Link
There is a bolted piece of plastic with a center hinge, and once upon a time I'm sure a blade was attached to it. I've taken these dimensions and photo to my local pool shop, and they say they've never seen something like this. I tried searching on amazon and google, but I can't find blades of the dimensions I need. It's also next to impossible to find center-hinged blades.
I'm hoping someone here can guide me to a solution so I can stop having this debris backup into my pool. Thank you for your time!
