Find out how to save water, energy and money and learn a bit about your water supply
The water leaving our treatment works does not contain lead and none of the water mains are made of lead.
Lead can be picked up where it has been used for the service pipe that connects the water main to your property or where lead has been used for internal plumbing.
If you are concerned that you may have lead plumbing or would like the drinking water checked for lead, please telephone our Customer Services team on 0330 303 0368 (calls charged at local rate) and we will arrange to take a water sample for analysis, free of charge.
Even if your home has no lead pipework it is still worth checking that the pipe running from the boundary of your property to the stoptap inside your home is not lead.
You may be able to see the end of the incoming pipe connecting to your internal stoptap.
Lead pipes are usually about 25mm (1 inch) in diameter and usually have a rounded swollen joint where they connect to the stoptap or meet other lead pipes.
Unpainted pipes are soft and dull grey but show the shiny metal beneath when scraped gently.
The water main in the road and the 'communication' pipe to the boundary of your property is our responsibility. You're responsible for the 'supply' pipe under your garden and into your house.
We'll carry out the following if you find lead pipework:
The permanent solution is to replace all lead pipework. The use of lead solder or lead pipes is now prohibited even for repairs.
Lead solder should never be use with copper pipes for drinking water and copper and lead pipes should never be mixed because this causes lead to dissolve more quickly.
If lead pipework is replaced, especially when a non-metallic alternative is used, the electrical earthing for your home should be checked by a qualified electrician because, in the past many homes have been earthed through the incoming supply pipe.
Phosphate dosing (treatment to prevent lead dissolving in pipework) is installed at around 50 sites throughout the region.
