Looking for help with low point drains
My camper is a 2013 Eagle Premier 351RLTS. We bought it in September of 2013. Until now, I've never done a complete winterization of this unit. All I've really done until now is make sure all three holding tanks are empty and leave an electric space heater on inside throughout the winter.
I live in East Texas, so my camper isn't at risk nearly as much as others may be, but I do consider myself to be a little lucky to this point. I am trying to be a little more proactive this time around. I've emptied the holding tanks and I've also drained the water heater for the very first time.
I am puzzled by the low point drains. There are two labels on the outside of the camper pointing to low point drains. Both are on the right hand side, one just forward of the basement, and the other just behind the basement. Underneath the camper, I see 5 total tubes sticking out under the belly. 2 of them are forward of the basement, and 3 of them are just behind the basement.
I found two valves inside the basement that appear to correspond to the two tubes forward of the basement. I assume these are the hot and cold low point drains for the bathroom. What puzzles me is that these two valves appear to be in the open position, and they've been that way since the day I bought the camper. I've never seen any water come from these tubes.
I can find no valves that correspond to the three tubes behind the basement. Could they be somewhere above the belly cover? Surely they didn't make it that much work just to open these valves.
I've looked under the kitchen and bathroom sinks, and see no valves in either location.
Somebody please tell me what I'm missing.
