Water hygiene

Looking after your water supply

Introduction

It is important that the water supply in your home is looked after properly 

Homes are considered to be at very low risk of water borne problems such as legionella bacteria and there are simple steps that can be taken to reduce that risk even further.

Legionella is a bacteria which naturally occurs in water sources such as ponds and lakes. In certain conditions it can also live in the water systems of buildings. If allowed to grow the bacteria can cause illnesses such as Legionnaires’ disease, which is a serious lung infection. 

Although anyone can contract Legionnaires’ disease some people are at higher risk. These include people aged over 45, smokers, heavy drinkers and people with underlying health conditions.

Simple steps to reduce risks

  • Make sure that taps and showers are regularly cleaned and kept free of debris and scale.
  • Make sure that all taps that have not been in use for 7 days, are run for at least 1 minute. This includes outside taps, showers, and toilets.
  • Disconnect and drain down garden hoses after use.
  • When returning from extended periods away from the home, make sure that all taps are run for several minutes.

Hot water 

  • Don’t reduce you hot water temperature from the pre-set level. Keeping hot water at between 50C and 60C will kill any bacteria which may enter the system.
    • If you notice the hot water temperature, drop unexpectedly report it to our Repairs Team immediately on 0345 2000 102. 

Cold Water

  • Legionella bacteria can’t grow in water below 20C, so it is important that your cold-water supply is kept cold.
  • If you have a bidet toilet, switch it off at the wall if you intend to be away from the property for more than one week. This is so warm water is not left in the cistern.
  • If you notice the cold water coming through your taps is warm report it to us on 0345 2000 102.
