Recirculation & Agitation
A recirculation valve is standard on all 4 PumpRight models
outlet plumbing assemblies.
How Recirculation Works:
When running a PumpRight pump at less than 20% of it
’
s maximum flow, it sometimes improves system sta-
bility to allow the pump to run faster. Opening the recirculation valve diverts some pump flow before the flow-
meter, causing the pump to run faster. The application rate is still measured by the flowmeter and everything
that passes through the flowmeter is applied to the ground. If the pump is surging at a low flow rate, open the
recirculation regulation valve until the pump runs smoothly.
Start with a quarter to a half turn.
OPENING THE
VALVE LOWERS THE MAXIMUM RATE THAT CAN BE APPLIED TO THE GROUND. Close the valve if a
higher rate is required.

How to modify for tank agitation:
If tank agitation is required, the recirculation valve can be re
-
plumbed to divert flow to the tank. All that is re-
quired is to remove the
1/2”
recirculation hose from the pump. Then replace the

HB on the
inlet side of the pump with a

plug which is included in your PumpRight accessories bag. Finally, install a
longer

hose from the recirculation valve back to the tank.
