Hey everyone, so I bought a house with an in ground pool and have had someone taking care of it, but have decided to give it a run by myself. Most of the stuff I have been able to figure out, but I'm trying to backwash the filer and have zero idea how to do it. I've looked online and saw some different things, but nothing looks like what I have. Anyone willing to help that I can send a picture too?

Thanks so much!
