So here's my valve setup:
The upper is suction, the bottom is return, yes? Now, I see on the suction side there are two pipes, one is for the 2 skimmers and one is for the main drain?
On the return side, why are there two pipes, and why is one side shut off? I have 2 eyeballs, both are running in this position. There's a pressure line for a cleaner (I'm using a robot instead), is it for that?
Guess I need to try it out, just don't want any nasty surprises :P
