A leaking toilet can waste 344,470 litres in 30 days ! Almost half (43%) of domestic properties in the UK have suffered water leaks. And even a seemingly small leak can loose approximately 20 litres of water every hour. The Autostopcock was invented back in 1993 as the first electric stop cock and won a Millennium Products Design award. It has since be updated to provide automatic 24/7 protection against burst pipe damage and can be configured to suit the property size and occupants lifestyle.
