Tier 2 Cleaning Nozzles
Tier 2 nozzles are more expensive but have better flow dynamics than Tier 1 nozzles. They have replaceable inserts that also straighten the jet streams as they exit the nozzle. When the jet orifices wear out, these nozzles can be restored to their full operating capacity by replacing the inserts. The water efficiency rating for Tier 2 Nozzles is 50-60% efficient.
