Sample interview questions: How do you handle situations where a backflow prevention device needs to be removed temporarily for renovation or expansion work?
Sample answer:
- Obtain Necessary Permits and Approvals:
-
Before removing any backflow prevention device, ensure you have all the required permits and approvals from local authorities.

Keep detailed records of the backflow prevention device, including its location, type, and condition, along with the date and reason for its removal.
-
Isolating the Backflow Preventer:
-
Isolate the backflow preventer from the water supply using valves or isolation flanges. This prevents water from flowing back into the water system during removal.
-
Drain the System:
-
Drain the water from the system downstream of the backflow preventer to prevent flooding or damage to downstream components.

Carefully remove the backflow preventer according to the manufacturer’s instructions. Ensure all associated piping and fittings are properly disconnected.

Cap or Plug the Piping:
