Checked customer complaint about about a leak on their water line. The customer had a leak next to a 1†gate valve. Presented customer pricing to replace the existing gate valve with a new quarter turn ball valve. After pricing was approved I turned off the water to the building and drained the system. After the system was drained I cut out the existing gate valve and damaged section of pipe. After the damaged section of pipe was removed I performed he installation of the new quarter turn ball valve. After the new valve was installed I turned on the water to the building and bled for air. I performed a leak search with the customer in the utility room where the leak was and at all of the plumbing fixtures in the building. There were no leaks when last checked. The customer was happy with their new shut off valve. Thank you for choosing COI Plumbing and Heating.
