If you have a water storage tank in your home, you know the risks of bacteria and pathogens accumulating in the tank. Here are some steps to clean the tank and prevent this problem from happening.
Disinfect the tank
Water tanks need to be disinfected regularly in order to maintain their cleanliness and hygiene. There are various methods available for achieving this. However, the most common method is by means of chlorination.
Using this method requires proper disposal of the chlorine solution. In addition, the interior surface of the equipment must also be disinfected. The free chlorine residual must be at least one milligram per liter (mg/L).
Another method of disinfecting a water storage tank is by using liquid sodium hypochlorite. This solution must be left to stand for at least six hours before being disposed of. During this process, a high-pressure water jet can be used to clean the tank.
Alternatively, you can use a 200 mg/L solution of chlorinated water to paint the inside of the tank. A stiff brush can be used to scrub the internal surfaces. Afterward, a rinse should be performed with clean water.
It is also important to fill the tank with only treated drinking water. Before closing the port of the filling system, the free chlorine residual of the water should be measured.
Remove remaining liquid and residue
Whether you are a newbie or a seasoned vet, it is a good idea to clean out your water storage tank at least once a year to ensure it lasts for many years to come. The tank has a number of moving parts, and they all need occasional TLC. Cleaning your tank is an easy way to prevent it from leaking, as well as a hassle-free way to keep your pets entertained. You should also take the time to inspect the inside of the tank to see if you have any corroded pipes, which can be a major headache if not properly addressed.
If you are lucky enough to have a water storage tank with a built in filtration system, be sure to use it. This will keep the scum off of your lawn and ensure you get the maximum watts for your buck. Using a water filter will also help ensure that you only end up with water that is good for you.
Repair a leak
If you suspect that your water storage tank has a leak, it’s important to repair it as quickly as possible. Not only will it help keep your home safe, it will also prevent your tank from causing damage.
Before you begin to repair a leak in a water storage tank, you’ll want to make sure the water tank is drained and sealed. The tank should be on a flat surface, so that you can work on it without risking injury.
It’s important to use a pressure reducing valve to stop the leak. Then, you can close off the tank with a strong adhesive.
Some leaks can be due to high pressure, sediment build-up, or even age. Whatever the reason, you should seek professional advice. In addition, you should not attempt to do the repairs yourself unless you have experience.
You can perform simple patch repairs on your own, but more complex repairs may involve relining the tank. When dealing with stainless steel tanks, there are specific tools you’ll need.
Prevent bacteria and pathogens from building up
If you want to avoid bacteria and pathogens from building up in your water storage tank, you need to clean the tank before using it. This can be done by running a solution of bleach through the tank. When you’re finished, rinse it thoroughly with water. You can also use a portable pump to remove the water from the tank. Make sure you clean the tank properly, according to your local regulations.
In a recent study, Legionella pneumophila was detected in a sample from the far end of a water storage tank. While this bacteria is known to cause Legionnaires’ disease, it may not be the only microbiological contamination that occurs in your tank.
The results from this study raise questions about the reliability of current water-borne pathogens. Specifically, the results from the water samples collected at the inlet ball valve are not representative of the overall condition of stored water.
Moreover, the majority of samples failed to meet regulatory thresholds for Legionella or Pseudomonas. These two bacteria are known risk factors for Legionnaires’ disease.
