Does my PRV need to be replaced?

Question

What is an acceptable pressure drop when a faucet is opened, if the PRV is functioning correctly and all the pipes are sized right? I have a 1.25” supply transitioning to a 1” and then splitting into two 3/4” lines for the hose bibs The pressure gauge at the hose bib reads 65 psi with no water running. When I open a hose bib next to the one being monitored, the pressure drops to 40 psi.  I see drops of 20-24 psi, even when if I were to open  a faucet in the home instead.
Thanks for any pointers.

Well it depends on the system most pressure reducing valves or regulators are there to prevent problems on the customer side , 60-80 psi is normal and most faucets can Handel this pressure.
I have seen 120 psi city pressure , without a pressure reducing valve or regulator there will be problems or earlier failures.
Is it time to replace OR repair your regulator
It sounds like a repair could take care of your problems for less than a replacement
