Why does my water have an odd taste/smell?

You may occasionally notice a change to the taste or odour of your drinking water.


Common reasons for this include:

Antiseptic or chlorine taste or smell
A very small amount of chlorine is used to disinfect the water we supply to you, and very occasionally you may be able to taste it. This can be avoided by storing water in the fridge overnight. Faulty washers can also cause an antiseptic taste.

Musty tastes or smells
This can be due to bacteria in your domestic plumbing system - disinfection of the system should help.

Metallic taste
Domestic pipes made of copper or zinc can corrode and cause a metallic taste. This can be avoided by running the tap briefly if the water has been standing in the pipes overnight.

Lead taste
Some plastic pipes are made with anti-oxidants which can cause a lead-like taste. The only remedy is to replace the pipes.
