Hi!
Long nightmarish story short, I ended up breaking off the tub filler pipe BEHIND THE WALL while trying to twist just the chrome filler piece off. 26 years of corrosion won over solder. Gut-wrenching sound...not good. Basically when I cleared a hole to have a look the pipe coming down from the on/off handle was crimped and not happy.
Anyway since then I took the whole assembly down to Home Depot to get replacement parts, consisting of a copper elbow joint and a 6" Galvanized Steel tube to fit onto the new replacement tub filler.
I straightened the pipe and soldered the joint ok, (well it was a messy job but it worked), used plenty of plumbing tape for the twist-on joint, and after double-checking for leaks I just duct-taped over the hole for a week's worth of observation before re-tiling. Better safe than moldy.
When I turn the tub on after an overnight's worth of sitting, I get a nice splash of rusty brown water. I don't have any other brown water coming from any other place in the house, so it seems it's just the little dabble of water that sits overnight in the filler tube.
Will this eventually resolve itself? The original pipe appeared to be galv. steel and never puked rust since we got the house. Plumbing is all copper otherwise. Isn't galvanized steel supposed to resist rust?? If this is going to continue, and I prefer it doesn't, what else should I have used?
Thanks,

Seriously, if they'd make cars that had joints based on something as tough as corrosion we'd all be safer. Plus, you could just leave it out in the rain to make it stronger. :)
