Should a pipe split you can be sure that there will be some damage, and this could be small or large, serious or not so serious. The actions taken and the speed will dictate this. The worst case scenario would be water coming into contact with your electrical supply.So below are some actions to take if you have a pipe split:1). Turn the main?water stop-cock, usually this is situated under the sink in the kitchen. Now, opening all your cold taps and flushing your WC should drain the water out of the systems pipework. A professional plumbing service like Catford Plumbers can repair split pipes. 2). Isolate the central heating system, this includes, immersion heaters or other heating appliances. Turn on hot water taps to drain.Note:Should there be even a remote chance of leaking water meeting your electrical system, you should isolate it at the consumer unit or main fuse at once. DO NOT go near any electrics if you are wet. If you find the leak quickly you can catch the water in buckets. However, if, say, the water is leaking upstairs and the ceilings are bulging, the room underneath might not be safe to enter. If the ceiling bulges with the weight of water, and you’re confident, pierce a small hole in it with a screwdriver and drain into buckets. If you are unsure about fixing a burst pipe by yourself, call in a professional like a Catford Plumber to find and fix the split correctly.Stop Pipes Freezing:a). Insulate your water supply pipes and your loft with the correct insulating material.b). Open up the loft door allowing the warmer air to rise from downstairs. This warms up the loft enough to prevent freezing.c). Isolate the water to your house if you are going away on holiday.Finally:Make sure that you sort what seem to be minor plumbing problems such as dripping taps. These can easily freeze up as these can freeze if the temperature drops and turn into major problems.
