Somebody came along and stole all the copper pipes to my water heater. I replaced them with CPVC, but now there is about half an inch of copper pipe still jutting out of the wall that I never saw until I had everything set up. When I turn on the water, my hot shoots over there and gushes from that pipe. I went halfway back on the supply pipe to that one and put a shut-off valve, but now there‘s no water to the bathroom or laundry room.So . . . how do I cap off that one little end of the pipe? I‘m almost positive that it has no other use, that it once led to an outside appliance that I have never seen. (It‘s a house from 1939.)
