Recirculation & Agitation
A recirculation valve is standard on all 4 PumpRight models
outlet plumbing assembly.
How Recirculation Works:
When running a PumpRight pump at less than 20% of it’s maximum flow, it sometimes
improves system stability to allow the pump to run faster. Opening the recirculation valve diverts some pump
flow before the flowmeter, 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 slowly until the pump runs smoothly. Start with a
quarter– or 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
required is to remove the 1/2” recirculation hose from the pump. Then replace the 3/8” MPT x 1/2” HB on the
inlet side of the pump with a 3/8” plug which is included in your PumpRight accessories bag. Finally, install a
longer 1/2” hose from the recirculation valve back to the tank.
