Turn off your water supply immediately using the stopcock — usually found under the kitchen sink or where the mains pipe enters your property. Switch off your central heating and any water heaters to prevent further damage. Open all cold taps to drain the remaining water from the system, then call an emergency plumber in Lisburn straight away.

Low water pressure in Lisburn can be caused by a leak in your supply pipe, a partially closed stopcock, faulty pressure reducing valve, or a problem with the local mains supply. If your neighbours have normal pressure, the issue is likely within your property. A plumber can carry out a pressure test to identify the exact cause — typically costing £50 to £80 for the diagnosis.

Insulate all exposed pipes in your loft, garage and exterior walls with foam lagging — available for under £10 from any DIY shop. Keep your heating on a low background temperature (at least 12°C) even when you are out, and open loft hatches occasionally to let warm air circulate. If you are leaving the property empty in winter, consider draining the system or asking a neighbour to check daily.

Yes, leaking radiators are a common plumbing repair. The leak is usually from the valve, the bleed point or a corroded joint. A plumber can typically fix a leaking radiator valve in under an hour for £60 to £120. If the radiator body itself is corroded through, it will need replacing — expect £150 to £350 including the cost of a new radiator.

Your internal stopcock is typically located under the kitchen sink, in a downstairs cupboard, or near the front door where the mains pipe enters your property. Turn it clockwise to shut off the water. If you cannot find or turn it, use the external stop valve in the pavement outside your property — you may need a stopcock key to operate it.
