What is premise isolation?
Premise isolation is preventing backflow into a public water system from a user’s premises by installing a suitable backflow-prevention device at or near the building control valve or water meter. Premise isolation for a building shall be required even if the water distribution system in the building conforms to current Ontario Building Code requirements because backflow into the public water supply can still occur if the individual protection fails.
