Winter Dump Valve trick

Antique Pedaler · 01-17-2009, 11:23 AM

Here's a way to keep the gray and black tank dump valves from freezing up. When the tanks are empty pour some anti-freeze down the toilet and sink. Then with the sewer hose cover on, open and close both dump valves allowing the anti-freeze to flow down to the cover thus keeping the valve gates coated in anti-freeze.

Nice idea.
I suppose you would want to make sure the trailer is sloped to the valve side, so the Antifreeze doesn't merely stay in the tanks.

Or move to California where it's not an issue.
Or not...I'm considering moving out.

I wonder what "regular" antifreeze does to a septic system.....I would, if I were to use this idea, pour in the non-toxic stuff. Do you think that would harm the natural bacteria that keep the septic system healthy?

If by "regular" antifreeze you mean "automotive", don't do it. It's poisonous enough to kill cats, dogs, and ex's. I'm sure it can't be good for our little bacterial friends.

Hey, Dave, we are in Calif too........at 3000'. That means our AS is winterized with the 'Pink Stuff' See the avatar. That's a light dusting of snow from Christmas night.....and I share the 'vacating' wish to leave Ca. But what else is there!
