I am surprised , you said toilet drain ? In copper ?

How easy or how difficult would it be to get to , to replace ?

If it is difficult to get to replace , I would be tempted to try to re-solder it . Either with soft solder or braze / silver solder it with something like Sil-Fos ?

Another field engineering solution would be one of the band strap repair clamps . Something like these .

ROMAC | Repair Clamps

Of course , if the whole line is corroded , internally , to the point it is like egg shells , the only practical answer is replace it . And one of the band clamps / straps might crush it ?

Might try squeezing it & see if it crushes . Only if you are prepared to replace it .

I do not know what your plumbing codes are , but if it were me ( and you do have to replace it ) , I would use PVC . Be sure to mechanically support / strap everything properly .

God bless

Since this is a drain , nor potable / drinking water , I would consider using tin / lead solder ( some where 50/50 to 95/5 ) instead of the new lead free solder .

I may be wrong , but I think the tin / lead solder is easier to use and may melt at lower temperature ?

You might even make a " patch " out of a piece of copper pipe , to go on top of it ?

In any event , use a wire brush and / or emery clorh and polish the heck out of the copper . Flux the heck out of it . When you start getting it almost hot enough to melt solder , take the flux brush and smear some more flux onto it .
Keep touching the end of the solder to the hot copper until it starts melting the solder . The heat of the copper should melt the solder . That way you have a much better chance of the solder holding .

Do not just direct the flame of the torch at the solder , to melt the solder . When the copper is hot enough , it will really flow and spread out . The flux helps keep the metal clean and free enough of oxidation , so you have a good surface for the solder to stick to .

When finished , just let the pipe cool naturally . Hopefully this is just a pin hole defect in the pipe and not a symptom or wide spread corrosion , from the inside out .

God bless
