Prevent water lines from freezing
Yahoo Message Number: 47892
Do I need to do anything else, more, whatever?

I went thru the following procedure:

Drained water tank and black and grey tanks.

Then I blew out my water lines from the city water inlet using a screw-in air hose adapter.  My compressor was set for 40 psi.

Removed drain plug from hot water tank, blew out that line, then replaced drain plug.

Opened each water tap one at a time, blew each out and closed it.
Then proceeded to the next tap.

Pushed down the toilet flush pedal and blew that line out.

Opened outside shower tap and blew that line out.

Added a cup of anti freeze to the sink and inside shower traps and poured a pint of anti freeze into the black tank.

I'm not sure what year LD you have, but for the more recent ones (and maybe yours too) you have skipped an important and potentially costly step. You are *not* supposed to use the city water hook up to blow out the system, as this ignores the water pump which would be still full of water that may freeze and destroy the pump. Rather, you are supposed to remove the output line from the pump and attach the air fitting to the line you've just removed from the pump. Then proceed to open all fixtures one at a time, including the hot water side of "dual" faucets etc. Next you need to run the pump, water tank already drained of course, for a few moments to get as much water out of the pump as possible.

BTW, I found complete step-by-step instructions for doing all this

Many thanks for the input.

I have a 2004 26.5 MB.

I plan to buy an LD or some other brand air hose fitting for the water pump but until then I am proceeding as I previously outlined ... PLUS ... I put a small electric heater inside the LD near the pump. I remove the decorative pump wall panel so warm air circulates around the pump and its water lines.
