Purpose
The waste tank rinse nozzles spray rinse water at the point level
sensors and at the waste tank interior surface.
Location
The waste tank rinse nozzles attach to fittings at the top of the
waste tank.
Physical Description
The waste tank rinse nozzle is a rotating sphere with small
holes.
Functional Description
The rinse water supplied to the waste tank rinse nozzles is
pressurized by the waste service vehicle.
The pressurized rinse water goes through the rinse nozzle
fitting and exits through small diameter holes on the rinse
nozzle. The force of the rinse water leaving the small diameter
holes causes the rinse nozzle to rotate. The rotating rinse
nozzle sprays the rinse water around the inside of the waste
tank. The rinse water spray flushes the point level sensors and
waste tank.
