The pump does indeed run both the pool and spa jets though I typically set the valve to reduce the spa jets so they're only pushing enough water to keep the spa from draining. Even with the low setting on the spa jets, the pool jets are pretty weak. Regarding the two-speed pump, is it possible to install a new two speed motor on my existing one-speed pump? I have an older Sta-Rite Max-E-Glas II - P4E6E-151L 1hp model:
