What it means
Pressure distribution sends effluent through a manifold and small-orifice pipes so each part of the field receives similar doses. It improves treatment on irregular sites and is common with mounds and ATU dispersal areas.
The system includes a pump chamber, supply lines, and often a return line or valve assembly. Clogged orifices or failed pumps cause uneven wetting and field stress.
Why it matters in Santa Cruz County
Engineered Santa Cruz County systems on narrow lots along Empire Grade and other ridgelines often use pressure distribution to fit treatment within tight footprints.
Homeowner tip
Report sputtering fixtures or uneven wet spots on the field promptly; they can signal pressure line problems.
