Restoration of services
You must have an expert check your propertys services before you turn them back on. The damage caused by the flood may not be obvious and switching on a service could be very dangerous.
An electrician will check the junction boxes, socket outlets, light switches and ceiling connections to ensure that there is no water trapped inside them.
Modern wiring can withstand a short period of flooding, but if your property was flooded for more than a couple of hours then you need to replace the wiring in your house. Consider re-routing cables to drop down from above.
Water and mud may enter gas systems during a flood. A registered engineer can check all your appliances, as these may be dangerous, even if they appear to be working normally.
Mains supply water should not be affected by flooding, but wash the taps and then run them for a short time to ensure that silt has not entered the system.
If you suspect that your mains supply has been contaminated contact your local authority and boil tap water for at least 20 minutes before use.
Check the pipe work in your house to ensure that it has not been damaged and check any insulation around the pipes and replace as necessary.
Water supplies that are not on the mains system, such as cisterns or wells, may be contaminated and should not be used until they have been tested over a period of time. Consult a specialist for advice.
Drains and sewers are rarely damaged by floods, but they may block and back up. Check this by flushing toilets and running taps. Report any blockages to the local authority.
If sewer repairs need to be made, consider installing anti-backflow devices.
If you have a private sewage system, make sure that there is no damage that could result in a health hazard. Saturated soils may interfere with its proper function. Do not use until the flood water level has subsided.
Service damaged tanks etc and have them inspected as soon as possible by a professional.
If flooding is likely to occur, make sure that the septic tank is kept full. In the event of a severe flood an empty tank could float away.
