Which side of the joint failed? The copper or the PVC? You have to be
scrupulously clean.
I use silicone sealer (like for tubs or aquariums) for a general purpose
"glue" - it sticks to most stuff pretty well. It's not good
structurally, but for something that's not seeing a lot of loads it
works ok - good epoxy joints are stronger than the material in some cases.
