There are many types of leaks that can happen in the home - the most common being to the plumbing system.Some leaks are harder to spot than others, as pipes can be hidden away behind walls or under bathtubs. If you have a leak but can’t see where it’s coming from, this could be:A roof leakA waste pipe leakA toilet cistern leakWhat to do if you spot a leakIsolate the leak as soon as possible by turning off the main stopcock or the individual isolation valve to the leaky pipe.If you can’t find or access the stopcock or isolation valve, place a container under the leak to catch the water. If it’s a minor pipe leak, grab a towel and wrap it around the pipe to soak up the water.You can report a repair here. If you’re a homeowner, call a qualified plumber or roofer.
