Installation Guidelines

  • This anti-siphon vacuum breaker must be installed a minimum of 6 inches above the highest point of the downstream piping to ensure proper operation.
  • It is critical that there are no shutoff valves downstream of the vacuum breaker, as this can impede its protective function.
  • The Watts Series 188A is specifically designed for non-continuous pressure installations. It is not suitable for continuous pressure or where backpressure conditions are possible.
  • Always consult and inquire with local governing authorities for specific installation requirements and compliance with regional codes.

Additional Details

The Watts Series 188A 2 inch anti-siphon vacuum breaker backflow preventer protects drinking water supplies from backsiphonage of contaminated water. It is engineered for non-potable service applications, including irrigation systems, firelines, and industrial processing, particularly in low-flow, non-continuous pressure installations.

Features

  • Constructed with a durable brass body and bronze internal trim for longevity.
  • Features a durable silicone seat disc, offering high heat and water hammer shock resistance and ensuring tight seating.
  • Equipped with a plastic disc float to prevent spilling under all flow rates, suitable for temperatures up to 180°F (82°C).
  • Automatically opens its atmospheric vent to prevent contamination upon loss of supply pressure or creation of negative supply pressure, and closes the vent while allowing water to flow under downstream demand.

Important Usage Considerations

  • This device is not designed for continuous pressure applications or conditions where backpressure may develop.
  • It must not be subjected to continuous pressure for more than 12 hours per ASSE Standard 1001.
