I see far too many frozen, split and destroyed plumbing parts including pumps, valves, and even water heaters each and every spring. I also see frozen and split heat exchangers for engines. This stuff is ALWAYS more costly than an extra gallon or two or three of propylene glycol.


The act of merely "seeing pink" tells you little to nothing. This owner sucked 2.5 gallons into the fresh water system of a 44' vessel based on the "I saw pink" protocol... D'oh.....
