Uses for a variable speed pump
I'm expecting a bid from my pool builder in the very near future. I've asked him to include a variable speed pump (VS-FHP2.0).
It is my assumption that to minimize installation cost and monthly electrical usage, the pump should be used to filter the pool, supply the spa jets and deck jets. I've seen discussions where a variable speed pump may or may not be a viable replacement for a Polaris booster pump (any thoughts on this?)
The Jandy controller [PDA-PS8] would actuate valves and send the correct speed to the VS pump for each "mode" (i.e. pool, pool+deck jets, spa, spa+deck jets, pool+cleaner, etc.)
Are my assumptions correct? In other words, if he comes back with additional pumps for the water features and spa, should I call "BS" on him?
