2003 surveyor winterizing help
Hi. I just got 2003 Surveyor travel trailer. I have watched many youtube videos on how to do this. I drained the hot water tank and left the plug out. My hotwater tank has only one by-pass valve so I guess it must have a check valve on the hot outlet side. I made a hose to attach to the inlet side of the pump to suck in the antifreeze. I pump and the antifreeze is just going out through the tank. Frustrating.
I initially thought I had a frozen line but it is only the hot water tabs that aren't flowing.
Anyone had this issue before?
