Why You Must Clean Your Water Tank

Water is the essence of life. This isn’t simply an old adage a spiritual guide wisely says to the young hero in a fantasy film, it’s the truth! Water enables life on Earth, keeping us, and our surroundings sustained and encouraging ongoing growth!

With all of this riding on its metaphorical shoulders, we hope our water supply is the cleanest it can be. From drinking and cooking to showering and washing our clothes, water is a large part of your daily routine, all flowing from a water tank. Nestled out of sight, your water tank cleanliness directly affects your water supply, meaning regular cleaning is absolutely essential.

The Risks

Here are some of the biggest threats that can arise from not cleaning your water tank regularly.


You’ve seen mold grow from a leaky pipe or on a poorly grouted shower, so you know water sources are a perfect breeding ground for bacteria growth.

Often, your tank is susceptible to stagnation caused by low circulation or blockages, which create an even more optimal space for harmful microorganisms to nest.

Some pathogens that could live in your tank are:

  • Legionella - known to cause a type of pneumonia called Legionnaires disease.
  • Enteroviruses - small viruses that can cause diseases like gastroenteritis and meningitis.
  • E. coli - contamination caused by human or animal wastes that cause short term health issues like cramps, nausea, and other stomach issues.

Additionally, there are certain water-borne diseases that may arise from an unclean tank like Cholera, Typhoid, and Lead poisoning.


Water tanks go through the natural aging processes and as such, they can accumulate rust. If your water has turned from clear to a brownish color, this could mean your tank is in need of a check-up.

This rust will affect your pipes, allowing them to corrode quickly, and can stain your sinks and showers if not properly cleaned.

The Side Effects

We know rust and bacteria are not two items you would choose to put on a menu or on a list of ingredients in your soap and shampoo. But a dirty water tank might leave you with no choice. The contaminated water finds its way to your faucets and therefore onto your skin and into your mouth.

The consumption of these harmful elements can cause dry skin and hair, bitter-tasting food, discolored laundry, and the development of any of the illnesses listed above

A tip from the professionals: If your tank is not clean, even the very best water filtration system may not be effective in keeping your home’s water clean.
