Hi I live in Western Washington where we occasionally get a hard freeze. I was wondering how many if you pump antifreeze through the black tank flush valve, and if it's really necessary. The dealer did not do this when I picked the unit up about a month ago, so I will pump some water through it to see if it has cracked.
I don't know if anyone actually sent water through the valve when the unit was built...
Any thoughts are appreciated!
