When I winterized my fresh water system last fall, a few people told me not to put any anti-freeze in the fresh water holding tank as it would leave a bad taste. Well, I never drink from the tank and I had a theory, so I decided to do it anyway. Here’s a shot of my tank last fall:
Notice that dark band at the bottom? You would be incorrect in thinking that it is simply the anti-freeze showing through the tank. The anti-freeze was not that dark. That dark band has been there since I can remember and all my clear lines were that colour. That black stuff is fungus and the reason why my water has always smelled musty. I tried to shock my system a number of times with bleach, but I could never get rid of those spore sgrowing in my fresh water system. I eventually figured out that I need to live off my holding tank rather than connecting to city water, but by that point the infestation was pretty severe.
My theory last fall was that letting my fresh water system, including the holding tank, soak in anti-freeze for six months would kill off everything living in it.
This is what my fresh water holding tank looks like now:
I have never, not even when I first started traveling, seen it so clear.
I feel that I made the right decision putting the anti-freeze through the whole system. I gave the fresh water system a good flush before leaving Lethbridge. There was a whiff of an anti-freeze smell while on my first holding tank of water, but now that I have refilled it a couple of times, all I get is clear water that I have actually felt comfortable brushing my teeth with. I’d call that an improvement!Share on Facebook
