“This really is a fantastic product. I suffered a leak in a 10ft length of 22mm copper pipe buried under a 5inch thick cement floor. I passed a length of 15mm tectite through this pipe like a heart surgeon's medical stent and saved the necessity of ripping up the floor. I needed to thread it around two right angle bends to achieve this. It is also good to look at and hplds any shape you bend it to.”
