What to do after a mains water leak | www.dehumidifier-rental.co.uk

We have recently dealt with a few leaks from mains water pipes. Most were under the floor structure and dealing with them required different solutions. Two of the examples involved burst lead pipes under a solid concrete floor, while the other was a stopcock leak under a suspended timber floor in a Victorian terraced house.

When you discover a mains water pipe leak we’d suggest the following steps:

  1. Turn off the stopcock tap on the rising main inside your property;
  2. If it’s not possible to turn off the stopcock within the property, or if the leak is closer to the flow than this tap, then it may be necessary to turn off the stopcock outside the boundary of your property, which is along the service pipe running between the water main (in the street) and the supply pipe within the property;
  3. Turn off any electrical supply that may be near the area of the flood, to prevent electric shocks;
  4. As with all leaks, clear away as much of the surface water as possible, to prevent spread of water and further damage of building materials. Mops, towels, buckets, wet vacuums – all essential items to have close at hand. Sanitising may be required particularly if dirty water has run in from outside;
  5. Contact a professional plumber to repair the leak. Accessing the leak may require opening access into walls or floors;
  6. Speeding up the drying should be considered; we hire a huge range of dehumidifiers, fans, heaters and other drying equipment and accessories. First however it may be necessary to undertake some preparation work. If water is trapped below floor coverings then these may need to be removed. Or if water has flowed into plasterboard stud walls these may need to be opened so that dry air can circulate inside the void;
  7. Drying equipment can be setup so that dry air is circulated around the affected area; over floors and into wall voids;
