Great, thanks.

So in essence, installing the Hayward 3/4hp SuperPump shouldn't pose a risk of damaging the system because it will actually output less GPM than the current pump that's in there now?

Also, would you recommend putting in a ball valve between the pump output and filter to manually reduce (throttle) the flow to the desired level? Is this safe for the pump's longevity? Does it cause a reduction in electricity usage?
