Thanks Mike.
One of these days I will attempt it. I can shut the water off using the shut-off valves. I've gone on youtube and watched a tutorial about it. If it's a simple washer I could probably do it. But they started talking about the 'seat' and that's when I could only imagine me $crewing everything up.
It's an old-fashioned laundry tub type faucet.
Maybe I'll take another look at it and see what I can figure out. When I don't know what I'm doing I tend to put it on hold until the situation becomes desperate.
