This Month, We’re Focusing on Your Freshwater Tank.
RVs typically have three tanks: a black-water holding tank, a gray-water holding tank and a freshwater holding tank. Holding tanks that are not adequately maintained can actually cause health problems, because solid materials, spores, and mold accumulate. Routine maintenance can prevent health problems and costly repairs. Always disinfect the freshwater tank at the beginning of your RV season. If you use your RV throughout the year, it’s a good practice to disinfect the freshwater tank when water has been sitting in the tank for thirty days or more. To sanitize the tank, you will need to know the gallon capacity. Next, turn off the water pump and make sure the water heater is off.
Step One: Open the fresh water low point drain valves. Turn on all faucets (sinks and shower) in the RV.
Step Two: After you have drained all fresh water from your RV, close all valves and low point
Step Three: After figuring your total freshwater tank capacity, add 1/4 cup of household bleach for every 15 gallons of capacity to your freshwater tank. Then fill the tank to capacity with fresh water.
Step Four: Turn on the water pump and allow the treated water to run freely from all faucets. Be
sure to flush the toilet several times until you can smell the chlorine. Allow the treated water to sit in the tank and water lines for at least 12 hours, but no more than 24 hours.
Next, perform Steps One and Two again, draining all the treated water. Then, with fresh water only (no bleach), perform Steps Three and Four.
Finally, Perform Steps One and Two again. Then leave the tank empty until you are ready to use the RV.
Be sure to:
-Always fill the freshwater tank with a hose designated for RV freshwater tanks.
-Replace inline water filters according to the gallon chart usage included with the filter.
-Avoid cross-contamination by storing all freshwater supplies separately from waste water supplies.
-When using water from campgrounds, attach the inline filter to your freshwater hose to filter out contaminants.
-Carry a spray bottle filled with a mixture of 1/3 bleach and 2/3 water, and spray campground water faucets before hooking
Enjoy the RV life!
