Brass tailpipe stuck - plase help

[joengn]

Seemed like when I put in the new bathtub the existing drain would work fine (same size as the old tub) but now I realize that the tailpipe is just a couple cm too short. So I was trying to remove the brass tailpipe, which is inserted into a galvanized nipple which attaches to the trap. I can't get the tailpipe loose, nor can I get that galvanized nipple to loosen up. Any advice? I tried a pipe wrench, hammering the tailpipe to loosen it up (although I don't have access to it from above so hammering it is tough). Thought about sawing it off but its so short as it is. I wouldn't even mind replacing the trap but everything is stuck! Please help!

tailpiece

Without access to the top you may be out of luck, because that tailpiece is probably corroded into the nipple. From the top you could bend it inward and pull it out, but not from the bottom. Forget about removing the nipple unless you have a couple of very big wrenches and room to put extensions on their handles.

Try using a propane torch. But have a fire extinguisher handy.

Well the tailpiece was stuck from above too. If it has to come to flames I'll be calling a plumber. Maybe it's just easier for them to cut the pipes back before the vent and trap, put in a union and redo the trap and all. Its not that big of a section. No idea what it'll cost me but you gotta have a shower!

Itsy bitsy problems like that is why I use PVC....

Heat sometimes works in these circumstances to expand the joint, while breaking it free from all the corrosion.

It's no more difficult to operate a torch than anything else you are doing. And, if it works, it can save you big bucks.

If you don't want to try the torch, you can squirt some PB Blaster in the corroded joints and let it react with the corrosion. Just don't use the torch after that, cuz the PB Blaster is flammable.

...a T215 should do it

clarification

just so im sure, do you mean get one of those couplings and a tailpiece extension. Put the coupling on the existing tailpiece (thats in the galvanized nipple) and the extension and then insert the extension into the drain assembly?

if so, whats the best material for the extension (which doesn't need to be long at all).

do they also sell those at Home Depot or are they typically special order from the website?

update

just thought i'd post a long overdue update since sometimes reading these I like to know the outcome.

I was able to saw off the old tailpipe flush with the top of the nipple. Then I put on an ABS coupling and trap adapter. Installed a new PVC drain assembly on the tub and everything worked perfectly. Tested the drain and overflow. Thanks for the replies.

Thats what I was thinking as read through the replies...but make damn sure you have enough room for the mission clamp.
As for the galvy drain...I get the shivers thinking about leaving it.
