Where should recirculating pump be placed?

[Martin Cooney]

I have a heat pump water heater with a thermostatic mixing valve, expansion tank, vacuum breaker valve and a recirculating pump. My system does not have a dedicated return line so APCOM BPV Aqua-Flash Bypass Pressure Relief Valves are installed at sinks at the end of each circuit.

Placement of the recirculating pump is a riddle in my mind. I have searched the web, but most systems are using dedicated return lines. Where is the recirculating pump normally placed in relation to the thermostatic bypass valve?

If you don't have a return line you don't need a circulating pump.
