My 2 HP main pool pump finally died and am planning on replacing it with a variable speed 3 HP Pentair 011018. I've searched and found several threads that confirm I can use this to also replace my booster pump (to drive my Polaris 360) but cant find anything that tells me how. Is it as simple as putting a t joint in the PVC? Should I put a valve? Is there anything else I should do to tie the outputs together?
Once the outputs are connected, I am guessing water flows through the Polaris at all times but only when the water flow is high enough to move it will it go. Is it any more complicated than that?
