Smkettner- I guess that is another option, but I don't have $217 I want to spend on another pump. I think my idea is much easier and cheaper.
I think you're missing what they're trying to tell you.
The water pump comes on when the pressure drops DOWNSTREAM of the pump drops below the set point. Both the INPUT to the hot water heater and the OUTPUT of the water heater are downstream of the pump.
In other words, without a recirculating pump between your T fitting at the tap and the T fitting at the water heater, NOTHING will flow anywhere. They are both under the same pressure with nothing to cause a flow.
