How should a backflow preventer be installed in a residential system?
A residential backflow preventer should be installed on the main water line by a licensed plumber, aligned with the flow arrow, accessible for testing, and protected from freezing.
- Place it after the meter/main shutoff, before irrigation or other cross-connections.
- Use a device matched to hazard level (RP, DC, or PVB).
- Install level with shutoffs and unions for service.
- Keep test ports reachable; arrange startup and annual testing.
