RV Fresh Water System Sanitized Using Vinegar & Water Heater

I use bleach. It attacks the DNA of the germs. That's why germs have not become immune to it and its been around for 200 years.

I put it in my FW tank and run it thru everything.

Then I drain the FW tank and the water heater. I don't let it sit in there for ever.

I refill them with FW and run it through everything again and drain everything again.

I've never had the smell of chlorine linger after thoroughly flushing system.
