Cause - A build-up of natural sediment and/or organic matter in the water mains, originating from the catchments. Another common cause is rusting in galvanised wrought iron pipes within the customer's property.

Solution - where the source of the discoloured water is identified as being caused by our system, we will work to restore water quality. Or if the problem is due to the pipes, they will have to get replaced.

Cause - It is usually the result of corroding copper pipes within the customer's property. The problem is almost always found in cold-water taps.

Solution - If required, we will come out and test the copper concentration in the water. This will determine if the corrosion is coming from the property's pipes or the pipes supplying the property. In all cases, we will provide you with a written report on findings and information on how to manage the problem.

Cause - Chlorine has been used effectively around the world for over one hundred years and the amount of chlorine added is nominal. Increases in the taste and smell of chlorine depend on several factors such as seasonal demands and the location of a customer's property in relation to the disinfection plant.

Solution - Chlorine evaporates very quickly. For drinking, place the water in a container and let it stand for up to two hours (or put it in the fridge to be used as needed).
