Sabre winterization question
I just finished winterizing my Sabre for the first time. Although this is my third fifth wheel, I went by my dealer recommendations which were pretty basic and the way I have always done it. With the exception of TWO things. A disclaimer at the bottom of their instruction sheet said "The use of air pressure to blow out the water lines will void your warranty". Never seen or heard of this before.
The other item and question I have is "after draining the hot water heater (Surburban 12 gallon) with anode rod, leave the anode rod out". I noticed when I picked my Sabre up last January it was winterized and the anode rod out. BUT, the threads on the water heater were very, very rusted. I had to use a wire brush to clean them prior to installing the anode rod and filling. I always put the plug back in my Atwood heaters and rods back in Surburban's after draining. Any advice or suggestions on this?
