Been messing around with the plumbing on our 92 breakaway. In scoping this all out, I looked in the interior bay with the fwd furnace (under the refrigerator). In there I see two water shutoff valves which I found in the shut off position. Anyone know the purpose for these? I have no diagram of the plumbing and I can and will eventually figure these out, but I'm just basically lazy and thought I'd ask ya'll!
thanks!

My coach has several valves normally closed which are drains for winterizing. If I follow the tubing along the floor I found 90 degree elbows going down through the floor.

Also you may have normally closed bypass valves near the water heater and/or the water pump allowing you to blow out the lines and refill with antifreeze.

Good luck on your quest. I'm still finding stuff I didn't know about in both my coaches.

I have two shut off valves that are off position also. These valves release the gray and black water from the holding tanks. Part of the waste water systems.

I do not have any shut off valves on the propane system for heating my coach, except for the stove pilot. You may have shutoff valves on your furnace or propane water heater that would shut off the appliance.

---

The valves may also be for the heat exchanger that heats the fresh water from the engine's coolant system. My valves for this application are under the coach on the frame rail.

---

If they are gray in color, possibly could be the fresh water plumbing system. Some valves may fill or drain the fresh water tank(s).

---

You may also have fresh water valves for your refrigerator's ice maker.

The few suggestions above should get your curiosity looking to see where the lines actually connect. Could be wastewater, fresh water, engine coolant, and/or propane shut off valves.

in my 92 breakaway, the two closed valves you are referring to are the hot and cold drain lines. you should also have a drain under the couch for the water tank and also one for the toilet.
