: You will be better off cracking the pipe out of the hub. To melt it out you need an oxy/acetylene cutting torch that you can both melt the lead and blow it out of the joint. It is both messy and possibly dangerous depending on the location, (and there are a lot of lead fumes involved).

: : cast iron hub. I've inspected the main pipe and its sound and I'd like to avoid a complete replacement.
: : How well does heat work and would I need a something bigger than my handyman's propane torch.

: : Thanks in advance,
