Top signs your water tank needs cleaning - Don't ignore these red flags

Your water tank is a vital component of your home’s water supply system. It stores and delivers clean water for various household purposes, from drinking and cooking to bathing and cleaning.   

However, over time, water tanks become contaminated with sediments, bacteria and other contaminants, compromising the quality of the water.  

To ensure the continued safety and reliability of your water supply, it is crucial to recognise the signs that your water tank needs cleaning.   

Below we’ll explore the top red flags that indicate it is time to give your water tank some much-needed attention.  

Murky or Discoloured Water 

One of the most obvious signs that your water tank needs cleaning is a noticeable change in the colour and clarity of the water coming out of your taps. If the water appears murky, brown, or discoloured, it’s likely that sediment, tannins, rust, or other impurities have accumulated in your tank. These contaminants can be harmful to your health and can also damage your plumbing fixtures and appliances.  

Unpleasant Odour or Taste 

Clean, fresh water should be odourless and tasteless. If you notice a strange or unpleasant smell or taste in your tap water, it is a strong indication that your water tank may be harbouring bacteria, sediment or other microorganisms. Ignoring this issue could lead to health problems, so it is important to get your tank sorted.  

Reduced Water Pressure 

A drop in water pressure can be frustrating, and it may signal that your water tank is due for cleaning. Accumulated sediments and deposits in the tank can reach saturation points and clog pumps and/or water filters and reduce the flow of water to your taps and appliances. If you have noticed a decrease in water pressure, it is time to investigate the condition of your tank.  

Strange Sounds from the Tank 

Your water tank should operate silently. If you hear unusual sounds, such as gurgling, banging, or popping noises coming from your tank, it could indicate the presence of air bubbles, sediment, or mineral build-up. These issues can affect the tank’s performance and efficiency. 

Visible Algae or Slime 

If you can see greenish or slimy substances in your water tank, it is a clear sign that algae, bacteria or other microorganisms have taken hold. Bacteria and other microorganisms can proliferate in dark, damp environments, which are often present in water tanks. Whereas Algae requires light to grow through photosynthesis, and its presence would suggest the tank is not airtight.  Any such growth not only affects water quality but can also clog pipes and filters.  

Leaks or Dampness around the Tank 

Check the area around your water tank for any signs of leakage or dampness. A leaking tank will result in water loss, can damage your property and result in contamination of the water in the tank.  It should be addressed immediately, starting with a thorough tank inspection and cleaning.  

Long Neglect or Irregular Maintenance 

Regular tank cleaning is crucial to ensure the longevity and functionality of your water tank. If you’ve neglected maintenance for an extended period or can’t recall the last time the tank was cleaned, it is high time to schedule a professional water tank cleaning service. Preventative care can save you from costly repairs and health concerns down the road.

Your water tank plays a crucial role in providing clean and safe water for your household needs. Ignoring the red flags that indicate it needs cleaning can lead to a myriad of problems, from health risks to plumbing issues.  At the same time, often what we can see with our naked eye alone cannot tell us how clean the tank is.  Our recommendation is an annual clean and certainly to never leave more than two years between tank cleans.
