THE IMPORTANCE OF
A PROPER PIT SYSTEM
Once equipment is washed, the untreated
wash water flows into your pit system.
A proper pit system for your application
is the first step in proper wash water
treatment and a critical element in any
wash water recycle system.
Consult your dealer to determine the pit
system configuration that works best
for your application.
