Preparing for freeze - did I do this right?

[poolnovice1]

We're expecting below freezing temps for a few days. I have three pumps - one for the pool and two for water features.

I've set the pool pump to run 24/7 during the freeze. As for the other two, I've drained the water out and plan to leave them off. Is this okay? Or should I run all three pumps?

Is this okay?

That's good for the pumps. Depending on the water features, do perhaps see if you can remove any standing water that is accessible to try and prevent expansion at those locations - if possible.
