Find the Source of Your Water Quality Problem

Find the Source of Your Water Quality Problem

The first step in solving your water quality problem is to work out whether the problem is in the water supply or in your plumbing. Below are some general guidelines.

Customer Responsibilities 

First, make sure there are no cross connections

Water quality problems can be introduced from other water sources on the property. You need to make sure there are no cross-connections between the drinking water supply and other water sources. For example, recycled or storm water.

Water storage like rainwater tanks, bores and swimming pools may also backflow into the supply. When this happens, it can potentially create water quality problems for yourself and your neighbours.

Is the problem the SA Water supply, or your property's plumbing?

The problem is likely to be somewhere in your plumbing when:

Only some taps are affected

If the problem is in the water supply, it will occur at every tap on the property, including the garden taps. If it doesn't, then the source is more likely to be somewhere in your plumbing.

If the problem does not occur on your cold water taps, there is a strong chance the cause of the problem is your hot water service. It could also be in the plumbing connected to the hot water service. There are exceptions to this in the case of odours, since heating of water can increase the level of an odour that was otherwise not detectable from a cold water tap.

The problem goes away after running the water

If the problem is in the water supply, it will not disappear after a few minutes of running the water.
