If you can make use of the outside water for cleaning or watering plants, that is better than wasting water uselessly!

1 - The first step in cleaning the tank is to empty the entire amount of water from it, to do this, open the outlet valve, and let the water flow. If the tank is attached to the house, a number of house taps must be opened to allow water to flow out.

2 - Since the tank valve or spigot is usually located above the bottom of the tank, you may need to remove the amount of water remaining at the bottom of the tank. Use a bucket to remove as much water as possible. Once there is a small amount of water remaining at the bottom, use a cup to remove it permanently.

3 - Then use a dry towel to dry the water at the bottom of the tank, ensuring that there is never any water.

2- Cleaning the tank from the inside

1 - First, sediment and residues must be removed from the tank without the use of a cleaning mixture.

2 - Then mix a quantity of hot water with the liquid laundry detergent, and scrub the inside of the tank. Use a rough brush, or an abrasive sponge to clean the inner walls of the tank. Wet the sponge with the cleaning liquid, and continue to do this around the entire tank, until you remove as much mud as possible, For dirt, you may need to use a long wand brush, depending on the size of your tank.

3 - Continue cleaning until you are satisfied that all dirt has been removed from the tank walls.

3- Sterilization of the domestic water tank

Be sure to clean the tank and pipes well from any trace of chlorine!

1 - Once you have cleaned the inside of the tank, you can then sterilize it. Use a hose to fill three quarters of the tank with clean water.

2 - Add chlorine to the tank at 50 ppm water volume. Follow these guidelines to determine how much household chlorine to use in the tank (1 gallon = 3.785 liters):

- Tank capacity is 250 gallons, use 4 cups of chlorine.

- Tank 500 gallons, use half a gallon of chlorine.

- For a 750-gallon tank, use half a gallon of chlorine.

- A 1,000 gallon tank used 1 gallon of chlorine.

3 - After adding the appropriate amount of chlorine, fill the tank with clean water completely. This will allow the chlorine to mix with the rest of the water in the tank.

4 - Once the tank is filled with chlorine and water, leave the mixture for 24 hours, making sure no one comes near the solution during this time, as it can be harmful to people and animals.

5 - Use chlorine strips to check the solution periodically for the amount of chlorine. Dip one end of the strip into the solution, and follow the directions on the package to determine the amount of chlorine present. If there is not enough chlorine, follow the steps to sterilize your home water tank from the beginning.

6 - After 24 hours, empty all the solution from the tank, throw it into the sewage system, and make sure the water is directed away from plants, lakes, and any areas that might be damaged by chlorine in the solution.
