Evening Everyone

Im trying to find a diagram/layout of the plumbing system for the 177SE trailer. Anyone know where I can find one ?

Regards
Dennis

AFAIK, there isn't one. It's pretty straightforward - what are you trying to do?

Sorry for the delay reply, make a long story short. When I left for my last camping trip I thought I had drained my fresh water tank. However after a four day trip (connected to city water) I noticed the fresh water tank was 1/2 full. So, I'm wondering how the system is plumbed and do I have something set incorrectly ??

On our 177, the fresh water drain is behind the right wheel - just a plug on a short piece of pipe hanging off the bottom of the tank. There are also hot and cold low point drains between the dump outlet and the wheel on the left side - that's post-pump, and won't drain the fresh water tank.

The city water is plumbed in after the pump, which shouldn't allow backflow to fill the tank. The plumbing you're concerned with is all visible/traceable via the access panel under the refrigerator.

  Ken, your diagram shows an open hose at the input of the water pump.  There must be more to that since the pump would not be able to draw water, only air.

Ken's diagram also shows a valve on that hose, which is there to let you pump antifreeze through the system to winterize it. That valve is normally closed. When winterizing, set the water heater valves to bypass, open that valve and close the valve going to the tank,  stick the hose in a gallon of antifreeze, and open the faucets, shower(s), and toilet one at a time until antifreeze comes out.
