Hi folks - nice to join this forum and I wish I'd done so earlier. Some urgent advice needed please..
Our plumber has had to repipe the central heating in our Victorian house because the existing system was single pipe. He has done this using plastic pipe and push fittings. The first time we turned the heating on, the ground floor system leaked into the underfloor void at a sagging 90 degree joint that sits in the middle of circa 4 metres of unsupported pipe. I've attached a video which shows exactly what this looks like..
I'm not convinced by his argument that the pipes don't need any support and only the fitting is at fault, so to save me the roundabout discussion could anyone please point me to the relevant guidance that defines how much sag is acceptable and what the support criteria is or isn't for 22mm plastic pipe?
