Taste and odour

Drinking water comes from lots of different sources, each with their own distinct taste due to the natural minerals they contain.

The temperature of the water can change our awareness of taste and odour too.

Some people are more sensitive to taste and odour and can notice tastes in water that others do not.

Many tastes and odours in water are related to plumbing or appliances within a home. 

Ways to reduce tastes and odours

You can reduce taste and odours by:

  • installing fittings that have been tested, approved and meet Regulation 4 of the Water Fittings Regulations.
  • only using freshly drawn water for drinking or cooking, taking it from the cold water tap supplied directly from the water mains. This is nearly always the cold tap in your kitchen.
  • flushing the tap if no water has been used in your home for several hours. This ensures that you do not drink water which may have lost its freshness while standing in the domestic pipework. You will typically need to flush around one litre of water – we recommend using this water for other purposes, such as watering plants. 
  • not reboiling water that has been allowed to stand and cool in the kettle.
