I figured I'd start my own thread to get help identifying the connections in my "Water Management Panel" for my new 5er. Some are labeled, some aren't and some are labeled with names that aren't very descriptive.
First, this is my 4th RV and I thought I knew my way around most systems on these things.
I bought a new 2016 Coachmen Chaparral 390QSMB 2 weeks ago. It has a central hookup station in the curb side basement. Here's a pic and what is labeled and what I was told during my PDI.
I'll start at the bottom.
The red and blue lines with stop cocks are low point drains. They dump out directly below. (Reference for bottom pic)
Pull handles on right are obvious and labeled appropriately for dump tanks. There is also a galley tank dump back under the kitchen slide.
Bottom water hookup on the left. Labeled "City Water Connection"- Seems logical.
Water hook up just above the City Water connection. I was told this was the black tank flush. The Caution label says "Do not use the tank flush valves unless the termination is in the open position." No other label.
Any idea what "Termination" is and how to open it? And this is a hose connection, not a valve.
Next ones going up are obvious. Outdoor shower and filter lines if I want to add one.
Now, about the 2 black valves and the black capped threaded connection on the upper right. The valves are labeled for what function you want, Tank fill, City Water/Winterize and System Use.
What does "System Use" mean? Using the water pump from the fresh tank?
Any idea what the 2 black valves actually do? I was trying to figure it out based on the diagram and function based on position. One sends the city water to the trailer vs water tank I think. Not sure what the other one does.
I forgot to ask about the black capped port right above the black valves was during my PDI. From another thread, I think it is probably a connection to hook up a hose to suck up antifreez when I winterize, but the other post said it should pull out. It doesn't. Just a male threaded connection under the screw on cap.
The dealer said the trailer was winterized when I did my PDI and they wouldn't hook up a water hose. (I bought it in mid-Illinois with temps below freezing). The cold side is air pressurized. You can hear air escape when you open a faucet. Not the hot side. The hot water tank has the drain plug in it and the bypass valves are behind a mounted panel next to the "Water Management Center" in the pic above. I stuck my camera over the top of the panel to get a shot of the bypass and the valves are in the normal (not bypassed) positions.
How can you pressurize just the cold side without also doing the hot side with the valves set like this? (Red and blue lines at the left in the pic. You can see the valves if you look close.)
Now for the last pic and question. This pic is 20 ft down the trailer under the kitchen slide. One pipe/hose hanging down is threaded. I'm pretty sure this is the fresh water drain. I can't find a drain anywhere else, but this is a LONG way from the city water connection. The red and blue hoses hanging down look like low point drains, but those are back in the other pic in the "Water Management Center". I suspect one or both may be fresh tank vents, but two? And why are they colored red and blue instead of blue? Strangely, the guy doing the PDI didn't know what these were either. There is a cap for the threaded hose back in the "Water Management Center".
I'm bringing the trailer home from storage this weekend to start putting things in and adding some storage organizers and I'll dig into this more. I wish I would have got a real "Chaparral" owners manual instead of a generic "Forest River" one.
