Even with a PRV, there's still a potential for failure, so the advice from others to NEVER leave a connection charged that can put a virtually unlimited amount of water into the boat is spot on. Stuff breaks, and always in a sequence that Murphy rides herd on. That's why I opt not to make a connection to dockside water other than a hose into the tank.

As I mentioned at the beginning of my post the preferred method was a flow restricter (orifice), no moving parts. This has nothing to do with pressure, only put a maximum limit on flow rate in case of a plumbing failure. A ball valve would be a poor choice here as it's to course an adjustment. Ideally a needle valve would be the best choice for controlling flow.
And as mentioned in my first post, I would never hook city water to my boat.
