A little help with my setup..

Hey all,

It won't let me attach photos of my pump/filtration setup for my inground 16K gallon pool yet but here are the imageshak links:

My problem is I really have no idea what each of those two valves do other then control the skimmer somewhat.

I recently added a salt system, and since then my vacuum navigator thing has not been working right and I think it has something to do with the valves. My pool has the skimmer area and then also a spot to plug my vacuum thing in.

If I plug the vacuum into the skimmer area it works fine, but if I plug it in to the spot that is made for it, it does not get enough suction to move. Prior to the salt system going on it worked fine.

Can someone help me with this?

The 2nd photo is of a sidewall manual vacuum port, that's plugged with a swing-up cover. The 1st photo shows 2 suction side ball valves. You have 3 suction lines -- possibly a skimmer, a main drain, and the vac line?
