Here are photos of my pump/filtration setup:
The port for the vacuum:
My question is about the two valves. I know one has some control over the skimmer but here is my problem..
I recently added a salt system, and when they did it they turned one or both of the valves because the water was low and I was not here at the time so when I came back the skimmer was not working. I got the skimmer working again, however my vacuum navigator thing no longer works when it is connected to the port for it. It seems to not be getting enough suction to move. Now if I take it out of there and connect it to the skimmer it works fine.
Could someone help me with this?
