Homeowner called and states that his garbage disposal had a weird sound and wanted us to come out and take a look to see if it was fixable. After arriving homeowner greeted me and took me to the kitchen and I could hear something hitting the blades when in use. I took a look inside and saw a black piece of material which I then took out and it was plastic piece causing the issue. Homeowner was very glad he didn’t have to replace it. I then did my inspection and found that the pressure slowly increased and the expansion tank was also blown internally. Homeowner agreed to the solution of replacing both the PRV and expansion tank which I started by shutting off the water and draining the home. Then I removed the old PRV and shut off and installed a new model with a new ball valve. Once it was connected I then replaced the expansion tank and turned the water back on. There were no leaks or issues found and homeowner is satisfied with the service provided and states that he has future work
