Came to clients wearhouse located in Vista Heights. Came for a leaking mop sink tap. Found both hot and cold taps to be leaking slightly when valves completely shut off. also found that main cold supply line shut off for mop sink was giving way as well. Gave client multiple options and client decided to replace all three valves. Had to shut of building water. Replaced the valves and turned water back on. No leaks were seen when fully pressurized. 1 year warranty on parts and labour.
