Drop in city water pressure

You may want to check the by-pass valves, i.e. the ones used for the winterization process. These tend to become flaky and will partially restrict water flow.

Just wondering there is any need to shut off the city water intake if using the pump?

So far I’ve been fortunate to be in places where my adjustable pressure regulator at the faucet was the limiting factor and have not experienced low water pressure yet but I know the day will be coming.

Thank you

Suspect more that WPump would stay off, UNLESS water pressure dropped below about 40psi, and then kick in :-)

I believe bypass valves would only affect hot water side pressure. Process of elimination - what is pressure using tank and pump? What is pressure when connected to City supply? Is there a difference? Yes would suggest something amiss in one side or the other which is a very short path as both are generally connected together in very close proximity. No would suggest downstream from that point and could be figured out by knowing which appliance closest to source is low pressure. One other thought of the cuff - valve for antifreeze input when winterizing?
