Looks like we had crossing posts. Appreciate the prompt responses!

The ECOSTAR 1000 RPM data point you provided is what I needed along with perspective re the filter.

My impression is that I will need to install a flow meter to get the GPM for the 1000 rpm in order to determine run time. Looks like the Blue White F30200 PR will work. I don't have much straight pipe after the filter but do have a 30 inch clear pipe run between the pump outlet and the filter.

Will the flow rate seen on the gauge mounted before the filter be much different than the reading if it is mounted after the filter?

Regards,

Chris
