OK, I was working on the plumbing when I realized that the Jandy two and three way valves have an "IN" marked on them. Some of the valves I did correctly and some I got reversed. The three way valves on the return header (manifold) are the right way but the ones on the suction side have the "IN" towards the pump which is sucking in water(was the only way to do them). I also have the two way valves about half the correct way and half the wrong way.
How critical is this? I can't see what the difference is.
Thanks in advance,
