While the metallic water taste and discolouration caused by corroded galvanised iron pipes is not a health issue (and therefore does not need to be fixed immediately), many people do find it unpleasant.
To manage this issue on a daily basis:
- Run affected taps for one to two minutes first thing in the morning to clear any water in your pipes.
- You may also need to do this at other times of the day, particularly if you leave the house for a few hours or have not used water for a reasonable length of time.
The cost of running taps for five minutes is 30 cents and, on average, uses 75 litres of water. To avoid waste, this water can be used on your garden. Please be aware running the tap will only clear the discoloured water; it will not fix the cause of the problem.
The only way to completely overcome issues associated with the corrosion of galvanised water pipes is to have the pipes replaced. If you wish to do this, it is advisable to install new pipes made from an alternative material, such as polyethylene or copper. A licensed plumber can carry out these works for you.
