How can I figure out which side of this bypass is incoming and which side is outgoing? Thanks a ton!
Probably an extremely silly question, but...

Turn the bypass valve off then check the other two to see which one has water pressure. (that will be the incoming) One will have water pressure the other will have some water just draining back from the system.
