A water main is the pipework that runs underground and is the main source that brings water to your home and your community. A water main break is when this main pipe bursts, cracks or becomes damaged. When this happens, the main water supply often flows from the pipes into roads or even near houses, causing potential damage.
If this happens, shut off your water main and call us on 01622 919012.
Kent Drainage also offer out of hours emergency service. If your water main bursts in the middle of the night, or after office hours call 07392 184307 or 07434 783704.
Pressure change or changes in the condition of the ground where pipework runs through are the main causes of a burst water main. As the water begins to freeze and expand as it turns into ice, the pressure inside the pipe begins to rise, eventually causing it to burst. This can also happen when the ground around a pipe freezes and heats causing the pipes to continually expand and contract.
The age or material of the pipe and certain soils that can corrode and rust the pipe material are also factors that may cause the fissure or bursting of a water main through weakening the pipes or creating blockages.
When drain excavation is carried out, drains can often be struck or knocked, for example by a shovel, a digger or other machinery. It is also possible for homeowners to knock pipework when carrying out their own digging or maintenance in their home.
If you hit a pipe and are unsure of what to do, call us on 01622 919012 to talk to one of our engineers directly.
These are some of the key indicators that a water main has burst or become damaged:
The length of time it takes to repair a water main is dependent on many factors, for example, the extent of the damage, the location of the break or if anything overlays the pipework, for example, gas or electric. Generally, it can take up to four to eight hours to fix a burst water main.
