Homeowner noticed that the water pressure in the home had spiked recently. Tested the pressure and found it to be 125psi. Homeowner was also interested in a while home water monitoring system, and the bladder in the expansion tanks were found to burst. Shut off the water to the home and drained the system down. Installed a new Watts PRV, and Moen Flo water monitoring system. Removed the two 2 gallon expansion tanks and installed one 4 gallon expansion tank mounting to the wall. In the Master Bathroom the toilet fill valve and flapper were replaced. Pressurized the system, removed the air from the lines, set the pressure to 65 and put the system back in service.
