What drains where?

Filed under: Uncategorized — donwood49 @ 6:28 am

I had a potentially disastrous event happen on a visit to Las Vegas. It had been freezing and I was concerned that the water hose would freeze up. I had heard that if you leave a trickle running through the hose, it wouldn’t freeze. I had hooked up the drain hose, opened the gray water valve and turned the bathroom sink on at a trickle. There is more to know.
I went out that evening and fortunately returned a couple of hours later. When I returned, the bathroom was just beginning to flood. The toilet bowl was full. After opening the black drain valve I cleaned up the spilled water and dried every thing out. It’s a good Idea to carry a wet/dry vacuum for just such needs. Fortunately nothing was permanently damaged but it did take a while to cleanup. Fortunately, the water that spilled looked clear but it had been through the mill so everything was disinfected as well.
What the heck had happened? The manufacturer had routed the bathroom sink to the black tank for some reason. It could have just as easily gone to the gray tank as I had thought. They must have done it to balance the tank use?
What was learned? Know where everything drains to. Don’t use that stupid trickle idea! Just use the water from your tank and the water pump and don’t even install the hose except to fill the tank. Wait for warmer weather.
Actually, we now tend to not even hookup the drain except when the holding tank needs to be drained or we know we’ll be at this site for a while.
