|Put the kibosh on it.|
The principle remains the same - you open it up, place it over the leak and then clamp it shut. Of course it's only a temporary fix but it gives you time to draw breath and decide how to effect a permanent repair.
The design means that it should be relatively easy to get it onto most pipework and it's small and neat enough to rest unnoticed in kitchen drawers for years at a time without cluttering up the place.
The current Kibosh is only designed to repair 15mm pipework, which means that for the next few months only your 22mm pipework will be prone to spontaneous bursting - for such is the law of Sod. However, different sizes will be out soon.
The 15mm version costs about £12 - when I asked at PTS they said that was the RRP so you ought to be able to beat them down a bit - but to fully cover yourself you're going to need a version for every pipe size in your home, which could make it an expensive business.
Another thing that worried me when I first saw it was that it was so small. If a pipe bursts because it froze, the ice usually causes the pipe to swell up a bit for at least 5cm on either side of the actual fracture. Can the Kibosh cope with this? Well, frankly I haven't a clue but I'd be surprised if they hadn't already considered this.
To be honest it looks a really well thought through design that's well worth buying for that rainy, floody, day.
Word of warning though - don't wait until you have a flood before reading how to use the Kibosh, have a practice first.
