While the booster pump can be fed from both the front and mid mount pumps I used the mid mount rotary pump as it was much easier to dial back the pressure for the small kids by adjusting the amount of recirculation water flow back to the tank. I bought a 2 1/2 to 3/4 GH adapter for the next tree watering as the kids had a hard time dragging the booster line around. -
Here is a drawing showing how the pumps are inter-connected Bob
