A chronically annoying hot water tap in the downstairs bathroom finally gave up any pretense of actually shutting off the water. Unfortunately the under-sink shut off valve was also corroded to the point where it wouldn’t shut off the water either. So we had a steady stream of hot water coming out of the sink.
Emma found a new faucet/tap set and picked up some new shut off valves. I turned off the water main, cut off the old shut off valves, installed the new ones, and replaced the sink hardware. It went pretty well overall, although I did get one skinned knuckle, and ended up soaked head to toe once (note to self: don’t accidentally loosen a compression fitting on a shut off valve, when you’re trying to tighten it, when the whole system is pressurized).
Some photos of the results:
