Our “plumber” drilled hole in main down pipe (plastic) instead of in the ceramic main out pipe (Black). Probably good that he didn’t touch that!
Anyway, the product he used to seal the “joint” has degraded over last two months, and is now leaking. Short term, I need to re-seal. Wondering if anyone can tell me what product to use?
The flexi pipe is the out from the washing machine.
