Ok, I bought a used 2001 21' feather lite in the spring.I had not used my camper anywhere that I didn't have full hook up. So last week when I winterized it I started thinking about my pump and how I had not heard it any. Can't find a switch? Don't think it has one. Can anyone bring me out of the fog on this? And if you think its fried, is there a access hole?.Any and all suggestions appreciated.
