Home water pressure 120 psi...

Speaking from experience. When I try to solder an existing copper pipe and the inlet stop valve leaks. And I have to plug the pipe with bread to keep it from dripping and complete the connection, the shutoff valve or ball valve always leaks. I don't remember having that problem with a ball valve. Of course, any type of valve can leak, but when a small leak gives false results when troubleshooting the problem, it's worth mentioning. And it's better to find out from the professionals at home if they can give tips for the home. They will be able to help with this much better.

Valves really need to be exercised at least once a year with water running through them. Big gate valves have had luck opening and closing them when open beating the bottom of the valve with a hammer to knock trash loose.

If the PRV is not operating correctly it can become an obstruction causing a pressure drop while the water is flowing.
