Sample interview questions: How do you handle situations where a backflow prevention device needs to be removed temporarily for renovations or construction work?
Sample answer:
When faced with a situation where a backflow prevention device must be temporarily removed for renovations or construction work, the following steps should be taken to ensure compliance and safety:
-
Obtain a Permit: Contact the local water authority to obtain a permit for the temporary removal of the backflow prevention device. This permit may require specific measures to be taken and will outline the timeframe for the removal.
-
Isolating the Device: Once the permit is obtained, isolate the backflow prevention device by closing the shut-off valves upstream and downstream of the device. This will prevent water flow through the device and isolate it from the potable water supply.
-
Disconnecting the Device: Carefully disconnect the backflow prevention device from the piping system. Note the orientation and any other specific requirements for the device’s reinstallation.
-
Cap or Plug Openings: Cap or plug all openings where the backflow prevention device was removed. This will prevent contaminants from entering the potable water supply.
