LeakMate is the number one tool to stop water leaks on burst pipes.
The clamp fits pipe sizes 10mm, 15mm and 22mm (3/8in, 1/2in & 3/4in)
The tool is so easy to use, see for yourself by watching the video below
This is why every house should have a leakmate tool, as you never know when you will need one. My accountant had a blind fitted last night. The fitter accidentally drilled into a central heating pipe 10 mm plastic as the photo shows and luckily the accountant had a leakmate tool at hand which I gave him during prototyping. He fitted it and stopped the leak and got the heating back on instantly. The time of night and the hidden pipe were not convenient but at least peace of mind that the leak is temporary repaired with no skill required.
