We have either been there ourselves or know somebody who has it's the dreaded water leak. Even yesterday myself as a plumber suffered this very same problem and its wrecked my new ceiling but luckily for me I had the skills to sort it.
That made me think that not many people have these plumbing skills I have and it ends up costing a lot more money to fix than it should. Here are a few tips which I hope helps you if ever in this situation.
The first thing you need to find is the water stopcock and turn off the water supply.
The stopcock- Make sure you know where your stopcock is located. It is usually found under the kitchen sink, but may be elsewhere. You may also have a few individual ones to different plumbing appliances (taps, toilets, sinks etc).
Open All Your Water Outlets (taps)- If you turn your water supply is turned off (or even if you can't) open all your taps. This will release all the excess water from the plumbing system or ease the pressure if you can't isolate the water.
Contact a Professional Plumber- It is important to do this as soon as possible as it may take a while for them to arrive. If there is more than one of you in the property, it is usually best for someone to contact a plumber while the other deals with the leak. Make sure you keep reliable plumbers contact details handy. If you've got an emergency in Liverpool or the surrounding area, Property-Serv our available 24/7 and can usually attend within the hour.
Electrical Items and Water Don't Mix- If you've got any electrical items located by the leak try and move them as soon as you can to prevent any damage. Turn off your electricity if you think it would be safer.
