After replacing my flapper ball and lift chain, the overflow tube
broke off (It's plastic). It looks as if they had used plumbers putty
to attach the tube to the base because where it broke off the tube is
slightly smaller than the base (yet not enough to fit inside) and
there is some tan residue. Can this be re-attached with a sealant.
If so, what kind?

I see the wisdom of replacing it, but since you asked, PC-7 and
probably PC-11 will stick to plastic, and if water starts to cover the
joint, will set anyhow. PC-7 will adhere even if the surface is wet
to begin with, but you may have to hold the part in place until the
epoxy starts to stiffen up. Which you would have to do even if it was
dry unless it would stand there on its own, or you could hold it in
place somehow.

Now sold in a 1" cardboard tube, but if you can find PC-7 in two 4-oz
cans it's a lot cheaper. If you don't let one part touch the other
part, and seal it well, it will last at least 10 years, probably much
more.

I usuually save up everything I neeed to glue with an epoxy, then mix
a larger batch and do them all at once, but that can be tricky since I
have to be able to clamp all of them except the last one I can hold in
place with my hands. And do it all before the epoxy starts to harden

Thank you,
