Turns out to be a royal pain. Case in point was the last two days trying to hook up the clawfoot tubs. I had set lines through the floor when running the plumbing this time last year. Complete with shutoff valves that were mated to chromed copper tubing. I went to connect the risers from the valves to the tub faucets and - the risers were 1/2" and my valves were 3/8". OK, cut off the valves and replace with correct ones. Run to HD and get the valves last night. This morning, turn off the water, and cut off the first valve and go to put on the new one and -----!!!???. It doesn't fit. It's supposed to fit on 1/2" hard copper tubing, but the stub was larger. Not big enough as 3/4". I suspect maybe a metric size?
OK, now I have an open pipe, water is shut off, valve doesn't fit I cannot even think there would be something available, and what am I going to do? Besides tear into the ceiling below and re-plumb? Dig around my scrap copper. 3/4" refrigeration line might slip over, but wait - 1/2" copper, the stuff that fits the new valve, looks like it might fit inside. Yes! It did!! Sweated the joint and slipped the valve on and I was home free. Someone was smiling down on me! Got the other three lines taken care of, and will finish the install on the drains in the morning.
