I would eliminate the lead bend and replace it with pvc. The lead bend is a ticking time bomb why play with it replace it.
I normally lead wipe the lead to lead connection using flemico #1 Warrenteed bar solder. If you cannot get flemico try getting 40/ 60 solder in bar form then lead wipe it
I removed the broken flange by perforating the lead filling between the drain pipe and the flange - i.e., drilling holes every 1/4-1/2 inch or so with a regular drill and then sawing through the filling with a power saber saw. Then pried the flange off with a pry bar. Wasn't as bad as I expected. - Dan
Lead free solder is required when connecting copper tubing used for drinking water. For electronic soldering as well as drain pipes in a home, solder with lead works very well.
it depends on what solder it is but the most common solder has 50% tin and 50% lead
No, solder is made of the two elements lead and tin.
Traditional electronics solder also contains resin.
solder is made by mixing lead and tin together.
it is not awesome.
Tin and lead make solder.
If the extisting drain is lead pipe it can be moved about an inch and the use a offset brass floor flange and lead wipe it in place that will give you the 3" you want
Solder is a compound, also called an alloy. Tin and lead are chemically combined to make solder.
