RV Fresh Water System Sanitized Using Vinegar & Water Heater

The problem with bleach is that people use too much. Per FEMA to sanitize a 5 gallon tank of water it only takes 1 teaspoon of household bleach (which is alread diluted by 92%). That is only 1 ounce of bleach for a 20 gallon freshwater tank and a fraction of what most actually use.

With bacteria growing in a hot water tank I would double the concentration and use 2 teaspoons of bleach in 5 gallons of water.

I carry a small 8 ounce bottle of bleach and and add it at the 1 oz per 20 gallons of freshwater to the camper.
