Step 3: Fill the tank with the bleach solution
Connect the water hose to a water source and insert the other end into the RV’s freshwater intake valve. Make sure the hot water tank’s drain valve is closed. Pour the bleach solution into the hose using the funnel and turn on the water supply.

Step 4: Fill the hot water tank
Open the hot water faucet in your RV to allow the bleach solution to flow into the tank. Keep the faucet open until you smell bleach, indicating that the tank is now filled with the solution. Once you detect the bleach odor, close the faucet.

Step 5: Let the bleach solution sit
Allow the bleach solution to sit in the tank for at least four hours. During this time, the bleach will kill any bacteria and disinfect the tank.

Step 6: Drain the bleach solution
Once the required time has elapsed, locate the hot water tank’s drain valve. Attach the water hose to the valve and direct the other end into a suitable drainage area. Open the drain valve to completely drain the bleach solution from the tank.

Step 7: Rinse the tank
To remove any remaining bleach residue, fill the tank with fresh water. Repeat the process of filling the tank, allowing it to sit for a few minutes, and draining it until no bleach smell is detected. This rinsing process ensures that your hot water tank is thoroughly cleaned and ready for use.
