I like that word, "saga"... looked it up online and discovered two definitions:
1. A prose narrative... of historic or legendary
figures and events of the heroic
2. A long detailed account.
Hahaha... I guess mine is number two
... and the saga continues...
One of the last things I did to the Scamp
yesterday evening was drain out some, but not all, of the pink RV anti-freeze from the rear (grey water) tank. My logic in leaving some in was just that since it won't freeze it can't hurt anything, and it might even protect the drain valve mechanism a little.
But since I am a bit of a scientist (suffering from a HUGE learning curve) I purposefully left the pail of pink fluid drained from the grey water tank on my front porch to see if it might solidify overnight.
Unfortunately, at exactly zero degrees Fahrenheit, it is rock solid... so I checked the camper... I had poured straight RVA down the sink drain, so the trap SHOULD be okay... same with the shower drain... the toilet "ball" has a little pink fluid around it, and it IS frozen, though the ball function still works fine.
It seems the harshest aspect of my learning curve here is that RV anti-freeze is nothing at all like automotive anti-freeze... with the latter, almost ANY ratio mixed with water will prevent freezing at zero degrees. Evidently with the former, 80% to 90% anti-freeze is not good enough. 100% is required.
I did consider this factor while following the winterization steps last night, and thought I had achieved my goal of 100%. Well, I KNOW that in many of the lines, and at least in the fresh water pump, there is pure RVA. But in the grey water tank this must not be the case, and since the small amount of pink fluid surrounding the top of the toilet ball appears partially frozen, I am thinking the line running to the toilet may have some water mixed in still.
Do I need to crank up my heater again today? I really have nothing better to do on Christmas, so I might just go out and do a re-enactment of yesterday... hahaha...
Regarding whether the water heater tank is cracked or not, I am afraid my guess is yes. Unless there is some mysterious line connection directly underneath the tank, I just don't know where else the fluid could be coming from when I open the inlet valve.
That said, if anybody knows exactly what the physical layout is on the underside of these tanks, and can offer me some hope, I'm listening...
