Cleaning Out Your Camper’s Waterlines

Cleaning out your camper or RV’s waterlines is an important step in maintaining the basic functions of your home-on-wheels. Cleaning out your water lines will help ensure that your hoses are free of gunk and odor and that your drinking water tastes fresh. Whether you are cleaning them out before winterizing your unit, or if you’re just keeping the lines clean for future uses, these simple steps will help you through the process.

Step 1: Drain your water heater

Make sure the power to your water heater is off.
Remove the drain plug located near the bottom left side.
Open the pressure release valve. Water should start draining.

Step 2: Locate the low points in your lines

The low points are generally located under your RV.

The manufacturer’s user manual may have instructions on where these are located. These are generally located under your RV in the lowest point in your water system, with separate lines for hot and cold.
Open the lines and let the water drain out.
Open your sink faucet to allow for drainage. Close up when the water stops draining.

Step 3: Clean out the holding tank

Open up your drinking water hold tank drain and empty the water out of it. Force any remaining water out by running the pump, but do not leave pump running after the water is drained or your motor could burn out.

Step 4: Flush the fresh water tank with bleach

When all your water is out, close up your valves and flush your fresh water tank with a bleach water solution. Make a solution of about 2C bleach to 30 gallons of water.
Next, fill your fresh water tank full of clean water. Turn your water pump on and open up your sink faucets until you smell the bleach water coming through. You should also turn on your outdoor shower if you have one.
Close the faucets and turn off your pump.
Let the system sit for 12-15 hours.

Step 5: Flush fresh water tank with clean water

Drain your entire system and fill the fresh water tank with clean water.
Open your sink faucets and run the water until the bleach smell has dissipated.
Your water lines are now clean and safe for drinking!
