You have to clean and disinfect your water storage tank to ensure your family's health. Cleaning the tanks will prevent and remove the build up of sediment, algae and microbial growth. We should not forget that all water contains some solids. Even if not visible to the naked eye, solids will accumulate over time in water tanks. Regular cleaning also allows stored water to appear and taste better.
You should clean your tanks if the water that comes out of the tap appears to be cloudy or if the water in your glass that has been poured with water from your tanks does not clear up after about a minute. The solids sitting on the bottom of a water storage tank could be the cause for the cloudy water. This often is a clear sign that your tank needs immediate cleaning.
