This summer I mentioned that a couple of the plastic elbows at the brass three-way valve for winterizing my Bighorn cracked and leaked.
I replaced those with brass fittings, but now I wonder if I got the pipe connections mixed up.
With the valve set to "winterize", I can draw antifreeze thru the cold water lines. I don't seem to be able to draw winterizing fluid thru the hot water lines.
With the valve set to "normal", I get hot water from the hot water taps, and cold water from the cold water taps, normal operation.
Looking at the three pipe connections, from front to back (front meaning the front of the RV that hooks to your tow vehicle) they lead to:
Intake side of the water pump
Intake (at the bottom) of the hot water heater
Hot water supply (at the top of the hot water)
My guess is the two near the front are connected backwards????
Anybody want to let me know the correct connections??? This is a Bighorn 3670, 2010... and I know the valve connections are behind the wall in the basement.
Thanks!!
