Did you try unscrewing it?

Yup, Sammy, I tried unscrewing it, even stuck a dowel in and used some gentle leverage. Nothing. Thanks, though.

I recommend turning off the water to your apartment before attempting to remove that fixture.

You may have to wind up getting a hacksaw and cutting it off... BUT then you will have to add a fitting to reach for a new spout.

Thanks, Debbi and Jim

Yesterday I tried the CLR for an hour, then flushed and tapped. Overnight I did the vinegar/lemon juice/baking soda in a baggie taped to the spout. Amazing amount of junk came out including solid flakes as big as 1/4" when I flushed it this morning with - wait for it - a Water Pic with a tiny brush. But still it doesn't turn. I've been using discarded toothbrushes as a lever. When they break, that's enough torque for me to risk without turning off the water to six apartments. i wish there was a tiny camera I could plug into my cell phone so I knew what was going on inside the spout. But I think it's time for a pro. Thanks so much everyone for the responses.

This is an apartment? Seems something your landlord should be responsible for.

Getting it off is easy with the correct wrench. But let someone else be responsible for a potential pipe breakage.

A toothbrush wont do it. You'll need a bigger wrench.

Thanks, weedmeister and sambah006. I surely do need the right wrench. But I'm not willing to take the chance I'll snap the pipe. There's no access panel, not even an individual apartment shutoff, just the one for the building. Peace out, and thanks again for the responses.

Have you spoken to the landlord.

I live in a multifamily home and there was a major flood last weekend caused by some (fill in the blank) who decided to do some repairs on his bathtub. The water gushed down from the 12th floor to the lobby flooding all in its path. I am just next-door to that stack and I am currently listening to the hum of drying machines from the water emergency company installed.

Tomorrow I need to have my walls tested for mold and asbestos before they can be opened up to dry out the interior. And then my wall will be patched and repaired - and I had MINOR damage compared to people in the direct path.

I wouldn't touch a plumbing fixture in a multifamily home - let alone a rental unit. You would be sued for any damage - not to mention your landlord suing you for violating your lease.

Not something a tenant should mess with. For a homeowner,this is the procedure. Hacksaw and split away enough spout (not the copper pipe inside) to access where spout screws onto pipe. Put channel locks or pipe wrench on spout and heat fitting while holding moderate unscrewing pressure on wrench. One of two things will happen,(A) treads will unstick and spout will turn,or (B) solder will melt and spout will turn as fitting slips on pipe. If spout screws off,you know how to do the rest. If solder melts,pull spout off with fitting,clean pipe and solder on new male fitting. The alternate if you don't have a torch or can't do soldering. You can buy spouts that mount on pipe without solder. Buy new spout,measure from wall to see how much pipe needs to extend for mounting new spout. I recommend cutting old spout as far from wall as possible then cutting pipe again to required length.
