3" copper is not 'de-sweated" as you call it.

Just reach into the pipe and grab the de-coupler nut and twist it counter clockwise with a pair of channel locks, the thing will come right apart.

The older it is the further the de-coupler nut will be down the pipe so you might have to reach in up to your elbow.

 

call a plumber....

 

Hopefully someone here can actually help me out, without a smart a$& answer.

 

Call someone that is licensed to do the work that you are doing illegally.

That or just use dynamite, it fixes everything.

 

Posting " Call a plumber" is helping you out. Where are you located?

 

3" copper?
De-sweat?
Propane?
I remember cutting a 3" copper pipe, horizontal, and having shet fall all over me. We all have to learn the hard-way what not to do.

 

Your gonna need much more heat than propane. Try some mapp.

 

Thanks for all the replies

 

No problem. I have a good supplier for explosives should you choose to take that advice.

 

I must say you are in a pickle. The make screw style plugs for such an occasion, they also make rubber caps that tighten with a hose clamp called Jimmy/jiffy caps depending on location. I have also heard of people taking an old inner tube and cutting a section out and slipping it over the pipe then folding it over and hose clamping it. This is not legal and is a temporary fix only.,as you do not want to emit sewer gases into the house. This will get you buy until you can buy the permanent solution and will keep your pipe free of debris. Good luck!

 

If you are abandoning plumbing, by code it needs to be cut and capped/plugged as close to the main as possible.

 

Sounds like some extra $ in scrap.

 

Sure

Get a roll of 50/50 solder and a brass CO flush plug. Sweat the brass plug inside and it's sealed. Sweat the threads around the diameter and it will seal for life. Then peel the ring off...good to go!
