Scope and Purpose
Description
These devices provide backflow protection against backsiphonage and backpressure in handheld showers. These are separate devices or are integral with handheld showers, tub fillers, flexible hoses, or components that are attached to a shower system. The device shall include two independently acting check valves in series or a check valve in series with a vacuum breaker feature.
General Requirements

Minimum Working Pressure
The device shall be designed to withstand an inlet working pressure of a minimum of 125.0 psi (861.9 kPa).
Temperature
Temperature Range
The device shall be designed to function at temperatures from 40.0 °F to 120.0 °F (4.4 °C to 48.9 °C).
Maximum Temperature Spike
The device shall withstand temperature spikes up to 150 °F (65.6 °C).
Connections
Connections for non-integral devices shall conform to ASME A112.18.1 / CSA B125.1.
Two Check Valves
Devices with two check valves in series shall comply with ASME A112.18.3 as a fitting with internal backflow prevention device.
