Protein skimmer overflowing?
I’m working on getting the gate valve installed on my Asm G3 skimmer. With the valve wide open the level in the skimmer quickly overflows the cup. I’m new to the Gate Valve and have no idea what to do to drop the water level so the cup does not overflow. I tried closing the valve and nothing, still overflowing. The below pic is the way the gate valve is installed, not my actual pic.
