CLEAN WATER REGENERATION WITH AUTOFLUSH
For installations with a high fouling potential, a back flush surge tank and/or a Separate Source Regeneration Valve (SEPS) or
three way valve on the inlet is recommended . During regeneration the three way valve will close the normal service inlet and
open the inlet from the back flush surge tank . The back flush surge tank supplies clean, treated water for regeneration . A 50
gallon (total volume) Pressure Tank is advisable . This is the minimum needed tank size to perform a treated water backwash .
For systems with AutoFlush, follow the instructions accompanying the NHBP . Make sure the drain receptacle can adequately
handle the flow from this line .
