Job summary Customer called John the Plumber out today because they had an issue with their garbage disposal making a humming sound. After speaking with the customer, they decided to replace a garbage disposal and replace the main valve. Main Water Valve: Technician removed old gate valve and installed a new quarter turn ball valve with a new hose bib. After installation, turn the water supply back on and check for leaks. Verify the valve opens and closes properly. Garbage disposal: Technician removed old garbage disposal that was not working. Technician then proceeded to mount the new garbage disposal to the sink, reconnect the plumbing and electrical connections, ensuring a secure and leak-free fit. Turn on the power, water, and garbage disposal to test for proper functionality. Check for leaks or unusual noises and ensure everything is working smoothly.
