Denso tape is supposed to seal up low pressure joints like drains. I know it is used as a temporary repair on gas joints. When shower traps drop into ceiling voids there is always a compression joint with a rubber seal to take the 40mm pipe. Denso promote their tape to temporally seal waste joints. This shower joint can eventually leak and then a big job to repair with a ceiling coming down. Has anyone used denso around the joint on the shower trap to ensure "if" the rubber seal fails there will be no leaks? A belt and braces approach.
