Sanitizing your RV’s Water Tank: How?

Water Tank Sanitation 2.0

Sanitation of your RV insures everyone on board a clean and healthy environment, specifically when it comes to your drinking water, which should not only be clean, but safe for drinking too.

So, when should you sanitize your RV? Sanitizing your RV should be done during storage and while on the road.

During storage:


If your RV has been sitting in storage, or has not been used for awhile, the fresh water storage tank, hot water tank and water lines are a great place for bacteria to grow and you don’t want that to happen. In order to remove these problems from your RV, you should sanitize your water system.


Here are some “DIY” ways in sanitizing your RV water tank:
  • Start with a nearly full fresh water tank.
  • Turn the water heater off and let the water cool.
  • Dilute 1/4 cup of household bleach for each 15 gallons of tank capacity in to a gallon of water.
  • Add the chlorine/water solution to the water tank. (Never pour straight bleach into the RV fresh water tank. )
  • One faucet at a time, let the chlorinated water run through them for one or two minutes. You should be able to smell the chlorine. (Make sure you are using the water pump and not an external water supply.)
  • Top off the RV fresh water tank and let stand for at least three hours over night is better.
  • Completely drain the system by flushing the faucets for several minutes each. Open the fresh water tank drain valve to speed up emptying the tank.and Open the hot water tank drain plug and drain until it is empty.
  • Close all valves and faucets and drain plugs.
  • Fill water tank with fresh water.
  • Flush each faucet for several minutes each repeating until the tank is again empty. (Make sure you are using the water pump and not an external water supply.)
  • Fill the tank again. The water should now be safe to drink but if the chlorine odor is too strong you can repeat the fresh water flush.
  • Your RV fresh water system should now be safe for use.
