Back to the Shurflow owners manual and found that flow restrictors on a faucet would cause this problem. Unscrewed the spray head, turned the faucet on, no pulsating and good pressure coming out of the faucet hose. I found not one but two flow restrictors in the spray head, removed both of those using a pick and the problem was solved. The pump stopped pulsating and have good flow at the faucet.

It dawned on me that these are residential faucets designed for 70+ psi of water pressure. Our water pressure is restricted with our pressure regulators to 55 psi, not enough pressure to open the flaps in the restrictor valves. It was an easy fix, about a minute using one of these. https://www.harborfreight.com/4-piec...set-66836.html

I've been trying to figure out how to get the restrictors out of the bathroom faucets in our 2019...what's the trick for them?

My 19 pressure seems to be fine so I have not looked at the faucets. Can you remove one of the water lines and see if there is a restrictor in the faucet, or does the faucet have to be removed? It will take a good flashlight if there is enough room.
EPA requirements all faucet now have flow restrictors, as Larry said, some faucets, have several of them. Just fought that problem with our newly remodel S&B bath.
