When, a bronze flange is encountered and in need of repair:

How do I remove the flange?

I understand that I will need to drill any screws out. If the lead is simply folded over and not soldered, it is a matter of bending it inward.

What is best for when the lead is soldered to the flange? Use a screwdriver and hammer to separate it from the flange?

What if the lead is messed up and cannot be folded and soldered to a new flange?

What if the lead bend has a hole in it below the point where a expanding flange throat would simply extend past it?

Is there any point in learning how to put a lead bend in or, do we now replace those with cast iron or PVC?

Thank you for all answers you decide to share.

IMO:

If one can unfold the lead, slip on a new flange, refold the lead that is a good repair.

Anything else just replace it all.



Old lead tends to 'crystalize' and turn hard/brittle.

Very very very hard to solder. Pun intended.

i don't know that i've ever encountered a brass flange that needed to be replaced ???

i think if i had to, i would remove the flange and use a push fit shoved down into the lead pipe.

if the lead pipe is bad i would cut back to the brass ferrule that the bend was wiped to and use a fernco to adapt to plastic.
