[VAC] Re: two requests

[Webmaster <webmaster@xxxxxxxxxxxxxxxxxxxx>]

When we had bought our Caravel, it had sat for two seasons with RV 
antifreeze in the tanks and lines.  We had to disassemble everything, 
scrub it, and the water still tasted funny all the next season.  It is 
OK now after 2 seasons of 3R Purogene 
(http://www.billydump.com/3r/purogeneinfo.htm)  Don't know if it's just 
the RV antifreeze itself, or the fact it was in there for 2 years.

We just drain all the lines & tanks now in the winter.

Many people install clear sight glasses or tubes that are vertical to 
the tank, and attach at the top of tank with the vent line and at the 
bottom with the drain line.  Most installations seem to be retrofits - 
don't know if they were ever an airstream option.
