System is fed by a trouble free Jet Pump powered by a 120/240V, 3/4 HP motor. 12 Mesh strainer prevents smaller debris from plugging spray bar holes.


Aluminum open-top system allows easy inspection of spray bar. The top is secured with Tri-Knob fasteners with rust resistant brass inserts for easy removal. The single point pad retainer allows complete wetting of the pad top unlike competitive systems where as much as the top 3" remians dry.

Large capacity Spray Bar features bell end couplers to eliminate 5” dead spots common with coupled pipe.

Large square poly trough offers greater capacity than round troughs and allows for trough to set directly on concrete foundation without brackets. Diamond Cut trough coverincreases drainage area by 33% to eliminate water pooling at the bottom of the pad. Water recycles quicker and pad life is extended because the pad bottom does not remain soggy.
