Newbie to pools here and I am trying to learn all I can. So grateful to find this site!
My question is: I have a Triton 2 sand pool filter with this valve on top and I don't know what/when I should be using it. Can someone enlighten me as to its function?
I understand the pressure gauge piece, but behind it there is a clear plastic thing with a turn that looks like it adjusts the pressure? When should I use this?
