Leaking water line needs new water regulator?

Respectfully, a working pressure regulator (PR) is a backflow preventor until the downstream pressure gets higher than the city pressure. At that point, the PR bypass valve opens making the system an open system. So yes, with a working PR, an expansion tank will help in keeping the downstream pressure within about 5 lbs higher than the PR setting.

My cousin says it sounds like the Pressure Regulator has went bad and that the shower is on a different one than the other things in the house. Could this be the problem? And how hard is it to fix? I have put a call into my landlord several times, but he's a slumlord and doesn't really care about anything. We can't even take a bath...even when running a tub bath I can get about 4 inches of water and the hot water is gone. I checked around the hot water heater and there are no leaks. What is this problem?
