Is The Water in your RV Fresh Water Tank Really Safe to Use?

Here’s an 8 step guide to quickly sanitizing your RV fresh water tank…

We’re so used to having clean water coming freely from the taps at home that we just kind of ‘assume’ that it’ll be the same in your RV right?

However, you can’t always trust the water away from home, and the last thing you want is to spend your vacation with a stomach upset when it’s easy and quick to avoid.

Follow this 8 step guide to get the job done – ideally you should perform this at least once every 6 months.

Before you start make sure you’re hooked up to electricity, you’ve turned off your water heater, and get rid of the anti-freeze in your pipes. Open the valves to the gray water tank and pay attention to your levels to avoid an overflow. Then:

  1. Turn off your water pump and open the valve of your fresh water tank. Drain your tank completely of all its stored water.
  2. Mix one cup of bleach or tank cleaner with one gallon (4 1/2 liters) of water. Pour the solution in your now-empty fresh water tank using a funnel.
  3. Replace the valve of your fresh water tank and turn on your water pump. Fill your fresh water tank with water.
  4. Once the tank is full, turn on all the faucets and water outlets in your RV, including the shower and just let the water flow. Pay attention to your water levels and make sure that the drain valve of your gray water tank is open.
  5. Turn these water outlets off once the smell of the bleach becomes really strong.
  6. Fill your fresh water tank again with cold water and let the water sit in the tank for about 8 to 12 hours.
  7. After the allotted time, turn on all the faucets and water outlets in your RV again and let the water run until the smell of the bleach goes away. Refill the fresh water tank and just keep flushing the water out until you’re sure that the bleach is completely gone.
  8. Refill your fresh water tank with clean water if you’re still using your RV. Empty your tank if you’re going to put your RV in storage.

And you’re done – as simple as that. When did you last clean your water tank?
