Scott,
I have a waterfall wall with three "Rockport" waterfalls.. They have the skipper look, so I assume they are the same basic thing.
I only have one pump and an actuator controlled valve turns the waterfall on and off.
I have the 3 HP IntelliFlo variable speed pump. If I had a single speed pump, I would not want the waterfall to be on the main circulation system.
I say this because when I run normally, the pump runs at 1,200 RPM and uses very little electricity. But to run the waterfall takes a bunch more power and I have to ramp the pump up to 2,900 RPM and of course it uses more electricity.
Thanks,
Jim R.
