I was living in my camper for 8 months. I disconnected my water pump and bypassed it. Now I am trying to connect it back up for normal operation. I feel like I am missing something..? I have a 2011 Ke...
Not exactly sure what you are asking about....but the water pump plumbing is simple and straight forward.
Line in has a screen, then the pump, then line out. There may be a open line with a valve on the inlet side. This is used to winterize by sucking anti-freeze from a jug through the pump and then through-out the system..
(This picture does not show the winterizing option:)
