Homeowner called and states that her garbage disposal wouldn’t turn on and it would just hum and she heard something hitting inside before it stopped working. Upon arrival homeowner greeted me and showed me to kitchen and I checked out the garbage disposal and homeowner agreed to unjam it. I unjammed the garbage disposal and found two pieces of plastic toys for toddlers which I removed and it works properly no issues. Did my inspection and found that the expansion tank was blown and the PRV wasn’t working properly the pressure was at 83 psi. Also noticed that the GWH are in serious using pex A pipe. Homeowner agreed to replace the PRV and expansion and I repiped the GWH using copper 18 inches. Replaced the PRV with new model and also the expansion tank. Homeowner is satisfied with the service provided.
