Call for pressure issues with water system. Arrive and met with Jordan. He states that they have noticed some inconsistent water pressure for several weeks. Mrs. Glover also mentioned that one of the showers emits an audible noise (consistent with water hammer) and that they have replaced some toilet fill valves. Jordan mentioned that the temperature and pressure relief line is constantly running. When checking pressure I found it to be 148psi @ ~10am on a weekday. Water tested at water heater. Thermal expansion tank bladder has ruptured, leaving tank full of water. T&P line is constantly running. The water heater also does not have a drip pan under it, thermal expansion is supported only by pipe which has sharkbite connections close. Replaced pressure regulating valve and main shut off valve. I also moved the prv and shut off to be more accessible, and to protect the front hose spigot with the prv as it was previously before the prv, and Jordan uses this hose spigot for lawn work
