The next step you have to do is to drain all the water from the tank. If the water tank is large ensure that the water you flush does not flood the surroundings. Also, see to it that the tank is empty and dry for effective results. If there is any water left behind in the tank, you can make use of a pump to remove it. After draining, you can even take a towel to wipe away the leftover moisture.
Step 3: Clean the Interiors of theTtank

You can use a power washer to clean the walls and the bottom of the tank. They help you to reach the nook and crannies of the tank that you cannot reach and scrub.

Step 4: Rinse the Exterior of the Tank
After cleaning the interior, move to the exterior of the tank. To clean the outside, you can use cold water and scrub the dirt accumulated on it. Rinse it for the first time to get rid of all the dirty water. Later, at the end of the cleaning process, you can rinse the tank exterior for the second time.
Step 5: Bleach the Interior of the Tank
The next step is to add a bleaching solution to the interior to clean and disinfect it. Here is how you can do:
- Use the bleach solution you prepared at the beginning of the cleaning process for scrubbing the interior.
- Wear your gloves and eye protection wear.
- Pour the bleach solution into the tank.
- For scrubbing, you can take a pressure washer to reach every corner and surface of the tank.
- If you do not have a pressure washer, you can use a mop with an adjustable head or any other cleaning tool that you can apply at an angle.
Step 6: Allow the Bleach Solution to Sit
After scrubbing the bleach solution to all corners, walls, and interiors of the tank, allow the solution to sit for at least two hours. Doing so will let the bleach solution clean any bacteria or other microbial contaminants present inside.
Step 7: Clean the Water Supply Lines (Optional)
Going a step ahead, you can even sanitize your water pipes at home other than the water storage tank. All you have to do is run the solution through all the pipes to ensure they are disinfected. You can make use of a pump for doing this job. This is an optional step. You can do it or skip it if you do not want to do it.
Step 8: Rinse the Interior of the Tank Thoroughly
The next step in the cleaning process is to rinse the tank exterior again for the second time. After you finish the bleaching job and let it rest for some time, start rinsing the interior. Make sure you rinse thoroughly and see that no trace of the solution is left behind. Bleach is toxic, and your drinking water should not contain it. So, rinse the tank interior properly. Also, if you ran the bleach solution through the pipelines, ensure that you run the faucets with hot water. Continue rinsing until there is no bleach or soap left.
Step 9: Rinse the Exterior of the Tank Again
After you rinse the interior thoroughly, move on to the next step. Rinse the exterior again to ensure it is totally clean and does not have any dirt or bleach marks on it.
Step 10: Refill The Tank Partially (Optional)
After you finish cleaning, sanitizing, and rinsing the tank with the bleach solution, start refilling it. You may fill it with drinking water halfway. Again, this is an optional step. You can do it or skip it if you do not want to do it.
Step 11: Measure the Chlorine Levels in the Tank (Optional)
If you still have a doubt that there may be traces of bleach solution left in the solution, this is what you can do. Take chlorine test strips and use them to test the water in the supply lines. Check for the results – if you notice the chlorine levels are nominal, you can directly go to the final step of the cleaning process. If you observe that the chlorine levels are higher, go back to step 8 and rinse the interior. Keep doing it until you notice a decrease in the chlorine levels. Again, this is an optional step. You can do it or skip it if you do not want to do it.
Step 11: Refill The Tank
After you finish cleaning, sanitizing, and rinsing the tank with the bleach solution, start refilling it. You may fill it with drinking water to the full.
