Due to a plastic waste pipe fracture and solvent weld failure by central heating installer I have to replace the internal waste stack from the kitchen sink and all connections to downpipe branch. So much for a ten minute job!
I've knocked out the cast iron bend mortared into the wall., the 40mm PVC pipe that was caulked into it and had to chip out the solder and twine joint that the bend entered a 112 degree branch through.
I assumed it contained asbestos.
I got a Polypipe 232 Caulking Bush to go from 40mm plastic to the cast iron socket, solder block /mortar to fill the 112 degree branch socket joint. I've cut a plywood jig to contain the solder flow when refitting but I can't find suitable yarn to compress into the joints. The wholesalers including a (drain specialist), DIY sheds I have tried looked at me blankly.
Does anyone know a good stockist of cast iron drainage suppliers that might have caulking yarn?
What is best practice for penetration of a to avoid thermal bridging, moisture bridging?
I'm also looking for pipe brackets to match existing but I'm not sure what they are called. They are something like electrical conduit crampets (hammered into mortar joint in wall at one side of downpipe and they wrap two thirds round the downpipe.
Does anyone know what these clips are called and where to get them?
Neighbours have replaced sections of cast iron with plastic bossed connections and it looked awful, so want to use traditional techniques.
Many thanks..
