Hey guys, new to owning a pool. I'm fairly versed in most pool things but this is one part of pools I don't quite get. We have an infinity edge pool, just got it with a new house. It's not that big of a pool in the first place, probably 16k-20k gallons. It was maintained... not too well by the last owners so I don't know if that is it.

Anyways, basically what happens is it fills up on the overflow and then... overflows for lack of a better term into my backyard. There are a bunch of weeds growing there now and it's a real pain. I've been told the way it pushes water back into the pool is by the pump that is attached to it, so I try to turn that on to lower the level and it doesn't seem to work. Can someone who knows about these pools plumbing/engineering give me a run down on it? I'd like to know the answer to my problem now, but I know if I am able to learn about how these things actually work deep down I can learn to fix any future problems on my own.

Thanks so much for the read.
