Counterflow Distribution Assembly
OVERVIEW Assembly of the entire system requires only a few simple hand tools. All connections are positive—yet the design allows repeated disassembly and reassembly.


Nozzles are installed in pairs—each supply pipe serving multiple pairs of nozzles. Multiple nozzle pairs per supply pipe mean larger pipe spacing and, therefore, lower installed cost than most other systems. The adaptor allows nozzle spacing on
3’-0” centers.

The nozzle outlet is always the lowest elevation in the distribution system. This arrangement is self draining when the supply water is shut off. There are no special valves to open or close.

The nozzle assembly is attached to the header/lateral using a unique design EPDM grommet that is inserted into the pipe—the entire assembly is attached with stainless steel strapping.
