The Darley Hydrant Diffuser is a heavy-duty hydrant testing accessory designed to safely reduce and redirect high-velocity water discharge during hydrant flushing and flow testing. It protects nearby property, vehicles, and landscaping while allowing accurate system performance measurements.
Features
- Slows and disperses hydrant discharge through internal steel diffusion grids to reduce water force damage
- Adjustable pattern diverter redirects water flow downward or to the side for controlled discharge
- Inlet adapter includes gauge slots for secure pitot tube placement and accurate pressure readings
- Limits discharge distance to approximately 5 feet, even at flows up to 1,125 GPM
- Pipe-style projection functions as a handle for easy threading onto hydrants
- Fully compliant with American Insurance Association Special Interest Bulletins
How It Is Used
The hydrant diffuser threads directly onto a standard 2½-inch hydrant outlet before opening the hydrant. As water flows through the unit, internal steel grids diffuse and slow the stream while the adjustable diverter directs discharge to a safe direction. A pitot gauge can be inserted into the inlet slots to measure pressure before diffusion, ensuring accurate flow testing results.
Who Uses It
- Fire departments conducting hydrant inspections and flow testing
- Municipal water departments performing routine flushing and maintenance
- Fire protection contractors and inspectors
- Water system maintenance crews operating in urban or high-traffic areas
Maintenance
- Inspect diffuser grids regularly for debris buildup after use
- Rinse with clean water following hydrant testing to remove sediment
- Check threads and inlet adapter for wear or damage
- Verify diverter adjustment mechanism operates smoothly before each use
