Performance Requirements for Backflow Prevention Devices for Hand-Held Showers
This standard provides performance requirements for backflow prevention devices for hand-held showers in the interest of health and safety. These devices provide backflow protection against backsiphonage and backpressure in hand-held showers. These are separate devices or are integral with wall-mounted or deck-mounted tub fillers, flexible hoses, or components that are attached to shower arms.
A downloadable version of this standard is also available.
