Cleaning an overhead water tank involves draining it completely, scrubbing the interior with a mild detergent or specialized cleaning solution, and then rinsing thoroughly to remove any residue. Avoid harsh chemicals.
Here's a more detailed breakdown:
Steps for Cleaning Your Overhead Water Tank:
-
Drain the Tank Completely:
- Turn off the water supply to the tank.
- Open the drain valve located at the bottom of the tank to empty the water. Allow sufficient time for complete drainage.
-
Initial Inspection and Removal of Debris:
- Once the tank is empty, visually inspect the interior for any accumulated sediment, algae, or debris.
- Manually remove any large debris (leaves, twigs, etc.) using a brush or scoop.
-
Scrub the Interior Surfaces:
- Prepare a cleaning solution using a mild detergent (like dish soap) or a specialized tank-cleaning solution. Avoid using harsh chemicals like bleach or strong acids as they can leave harmful residues.
- Use a long-handled scrub brush to thoroughly scrub the interior walls, floor, and ceiling of the tank. Pay particular attention to areas with visible staining or algae growth.
-
Rinse Thoroughly:
- After scrubbing, rinse the tank thoroughly with clean water. This step is crucial to remove any remaining detergent or cleaning solution residue.
- Repeat the rinsing process multiple times until the water runs clear and there is no trace of soapiness.
-
Disinfect (Optional but Recommended):
- For added sanitation, you can disinfect the tank. Use a diluted chlorine solution (e.g., 1 cup of household bleach per 50 gallons of water).
- Let the solution sit in the tank for approximately 30 minutes.
- Drain the disinfectant solution completely and rinse the tank thoroughly several times with clean water until the chlorine smell is gone. Ensuring all traces of chlorine are removed is vital.
-
Final Inspection:
- Before refilling the tank, conduct a final inspection to ensure all debris, detergent, and disinfectant residues have been removed.
- Check for any cracks or damage to the tank's interior and make necessary repairs.
-
Refill the Tank:
- Close the drain valve and turn the water supply back on to refill the tank.
Important Considerations:
- Safety First: Always wear appropriate safety gear, such as gloves and eye protection, when cleaning the tank.
- Frequency: It's recommended to clean your overhead water tank at least once a year, or more frequently if you notice any signs of contamination.
- Professional Cleaning: For large or difficult-to-clean tanks, consider hiring a professional water tank cleaning service.
- Sunlight Prevention: If possible, consider measures to reduce sunlight exposure to your tank to minimize algae growth.
- Tank Material: Different tank materials (plastic, concrete, steel) may have specific cleaning recommendations. Check the manufacturer's instructions if available.
By following these steps, you can effectively clean your overhead water tank and ensure a safe and healthy water supply.
