Bleach is commonly used to disinfect water tanks and ensure safe drinking water. To effectively sanitize a water tank, the general guideline is to add 1/4 cup of household bleach per 15 gallons of water. This amount can vary based on the concentration of the bleach and the size of the tank, so always verify the instructions on the bleach container.
How to Calculate the Right Amount of Bleach for Your Water Tank
To determine the correct amount of bleach for your specific water tank, follow these steps:
- Determine the Tank Size: Measure the water tank’s capacity in gallons.
- Check Bleach Concentration: Most household bleach contains 5-6% sodium hypochlorite. Ensure you are using the right type.
- Calculate Bleach Requirement: Use the formula:
[ \text{Bleach Needed (cups)} = \frac{\text{Tank Capacity (gallons)}}{15} \times \frac{1}{4} ] - Mix Properly: Add the bleach to the tank and allow it to mix thoroughly with the water.
