A reminder for those who sanitize the water system.

According to my Winnebago manual, it is 1/4 cup bleach per 15 gallons of tank capacity.

Fill the tank, pump through all plumbing, including the water heater.

Let it sit 4 hours.

Drain, and flush with water.

If you double the amount of bleach, you can cut the sit time down to 1 hour.

I have been told that if you use chemicals in the black tank (not the geo method) that you should not put bleach in the tank. The bleach kills the enzymes in the chemicals and tank and they no longer do their job of breaking down the waste.
I'm not a chemist, so I don't really know if this is true, but it is what I've been told........

I like filling the tank to get any bugs that might be near the top.

Is it necessary to completely fill the tank or can you just do half tank?

I let the bleach mix sit overnight - no downside, doesn't cost anything, and no additional work.

I use a measuring cup and pour the bleach into the fill hose then after sitting turn on the water to fill tank.

That's a cleaver way to take care of the hose! Think I'll use a 5 gallon bucket.

Be careful around that cleaver!

......while getting the water heater in the 5 gallon bucket..;)

Don't forget the fresh water hose either!

[Johno02]

Best be patient and do as recommended by manufacture says.
