Customer called in needing someway to isolate and drain down their pot filler when outside reaches freezing temperature. Customer does have access to water line in the basement for it. Quoted customer pricing to get line rerouted and have a ball valve to shut water off when outside reaches freezing. Customer agreed to pricing. Went ahead and rerouted pot filler line to basement sink water line. Added a ball valve before it. Turned pot filler out and water no longer comes out. Showed customer procedures to drain pot filler. Turn ball valve off first, turn water on for cold side in bar sink, turn one pot filler and water will drain down to basement bar sink. Checked for leaks and no leaks detected. 1 year warranty on reroute of water lines.
