**Locate and Turn Off the Stopcock** The stopcock is your main water shut-off valve, usually under the kitchen sink or where the mains enter your home. Turn it clockwise to stop water flow. If you have a burst pipe, this is your first defence. Practice turning it off so you can do it quickly in an emergency. Remember, every second counts when water is gushing.
**Turn Off the Boiler and Water Heater** If water is leaking near your boiler or water heater, switch them off immediately. For gas boilers, turn off the gas supply at the meter if safe. This prevents electrical shorts and gas leaks. Drain the system by opening taps to relieve pressure. A condensing boiler may have a plastic pipe that can freeze – protect it in winter.
**Contain the Water** Use buckets, towels, or a wet-dry vacuum to remove standing water. If the leak is from a pipe, apply plumber's tape or a pipe repair clamp as a temporary fix. For radiator leaks, turn off the TRV valve and isolate the radiator. Protect furniture and electronics by moving them away. Open windows to aid drying and prevent mould.
**Call an Emergency Plumber** Have a reliable emergency plumber's number saved. Explain the situation clearly – mention if it's a burst pipe, leaking boiler, or blocked drain. While waiting, continue to monitor the area and keep the stopcock off. Do not attempt major repairs yourself; focus on damage control. A professional will have the right tools for pipe repair and leak detection.
