2 returns and 1 skimmer...

The pressure on the filter (read from the gauge on the EC-65) is just about ~15 or so (I backwash when it gets to ~20). But is pressure read at the filter what one can expect from the returns?

Also... I do have the plumbing for a cleaner which was never hooked up. I think I may put a Jandy Valve in so I can redirect the water to the cleaner and the returns.
