The Exeter MP has urged Devon County Council to take legal action to force contractors to resolve ongoing problems with the water supply at a number of city schools.
It follows the revelation last week that an employee of Carillion, the company responsible for managing the buildings, recently doctored a water safety reading at St Peter's school.
West Exe school has also had problems leading to pupils having to drink bottled water.
Ben Bradshaw says it's time something decisive was done.
