Guest Blog: Watersafe – Up to half of drinking water quality failures caused by home plumbing

The annual reports by the drinking water watchdog for England and Wales shows water supplies are among the best in the world – with 99.97% and 99.98%, respectively, of samples collected and tested meeting the required standards.

However, the document also reveals more than 36% of water quality failures in homes in England, and 51% of failures in homes in Wales, stem from plumbing issues in customers’ own properties.

Poor plumbing practices and fittings are one of the main causes of drinking water quality being affected, after it has been transferred safely from water mains into people’s homes.

These can include incorrectly connected appliances likes dishwashers and washing machines, misconnections to waste pipes, poor quality taps and fittings and even contamination from home oil storage tanks.

The Drinking Water Inspectorate and WaterSafe, the national register of approved drinking water contractors, are urging people to always use a WaterSafe member to work on their plumbing. This shows the installer is specifically trained in the regulations that help keep drinking water healthy in homes and businesses.

Julie Spinks, Director of WaterSafe, said: “The Drinking Water Inspectorate’s latest annual reports for England and Wales tell us our water supplies are world class and we want to play our part in making sure drinking water is as healthy when it comes out of customers’ taps, as it is when it leaves your local water company’s mains and pipes.”
