Re: [A/S] Purging antifreze

[Charlie/Betty Burke <cbburke@xxxxxxxxxxxxx>]

It is an unfortunate, continuing piece of misinformation published 
in media such as Trailer Life. For years, despite pleas to the contrary, 
they have continued to describe the steps of winterizing to include 
dumping RV antifreeze in the fresh water storage tank. No self respecting 
RV dealer that I know of would do this, certainly none that have ever had 
to deal with the consequences. Our procedure  for the 10 years I've been 
doing has been to blowout the system with an emphasis on blowing the water 
out of the water heater rather than draining it, then connecting a fitting 
at the draw side of the pump and using it to pump anti-freeze through the 
rest of the plumbing with a bypass on the water heater. You don't want 
anti-freeze in the fresh tank or the water heater. The benefit
otherwise is it moves any water out of the dips and crannies of the rest of 
the system. In our neck of the woods we guarantee our jobs no mater how low 
is goes so we don't take any chances.
