OK to restrict flow through single-speed feature pump?

[robbief00]

I have a 1 hp Whisperflo pump for my tanning ledge bubblers and rock wall waterfalls. This pump and plumbing is completely separate from the main pump and filter.

The bubblers and waterfalls have individual manual valves to adjust flow. I want to turn down the bubblers so they don't spray up as much but when I do that too much flow is diverted to the waterfalls. Is there a problem with having all valves (bubblers and waterfalls) closed halfway. Does that put too much strain on the pump if the total flow is restricted?

Unfortunately, the pump is single speed so I can't adjust the RPM to dial back the GPM.

It will not hurt your pump at all. Your psi will go up so note your new psi as soon as you make the change and remember it.

As long as some water is moving, you will not hurt the pump or motor.

Thanks! I was concerned since it seems like the pump gets louder the more I close off the valves. I found this thread also that was related to my question. It seems an added benefit is less power consumption with more restriction (less flow).

Yup, I almost mentioned that as well
