Hello gents. I'm stuck on this one so could use a few tips. I'm a maintenance engineer and the building I work in is very old which means that the majority of local isolation points are either seized or nonfunctional. Generally, a leak means isolating the whole site via the plant room or cutting in live and slamming on a lever valve which is something I would rather avoid if necessary. I have some of those Kibosh pipe clamps for 15mm and 22mm which work a treat so I am wondering what methods there are for sealing live leaks on larger pipes (28-35mm). I was thinking along the lines of a quick setting metal/epoxy? Is there such a product out there? Any help would be appreciated. Cheers!
