Arrived at location on 6/20/22 - While on site for other issues Jessica asked me to look at the sink to the right of the sauté line. She also wanted me to look at the drain for the hot well at the right of the sauté line. Found cold water side leaking on the valve. Hot side didn’t look good either. The drain line runs very hot water down it and has disintegrated the drain valve. Went to APR supply in new Oxford and gathered all parts needed. They needed to order the TNS brass parts. They will be available for pick up tomorrow morning. Returned to location on 6/21/22 - Picked up parts from APR supply in new Oxford and drove to site. Made new drain line with new valve and installed. Replaced both sink cartridges and turned water on. There is no more leak at the drain line or the sink valve. The hot well that the drain goes to is deteriorating at the bottom and is leaking slightly. I advise Jessica on this so she is aware. Complete
