How can you deal with leaks at home?

House

Water can be incredibly damaging to a property, affecting everything from the fabric of the home – wallpaper, plasterwork, and carpets – to expensive electrical items such as computers and hi-fi equipment.

Unfortunately, many leaks can go unnoticed until they start causing real problems, so follow our guide to making sure this doesn’t happen to you.

How to check for leaks in the home

How to check for leaks if you have a water meter

  • Make a note of the meter reading
  • Don’t use any water for the next 30 minutes or so
  • At the end of this period, check the meter reading again; if it hasn’t changed, you are free of leaks. If the reading has gone up, this is the possibility that water could be leaking somewhere in the property.

Note: If you have an older property, you may have a shared water supply, which could give the impression of a leak when in fact it is just your neighbour using their water.

You can read more about checking for leaks in this way at Anglian Water’s website and Southern Water’s site or find your own water provider here.

How to check for leaks if you don’t have a water meter

If you don’t have a meter, you will need to carry out a more thorough search of your property to establish if you have a leak.

  • Look for damp patches or mould on ceilings and walls
  • Check for rust and/or water stains on floors and carpets
  • Check the water pressure is normal; a reduction in pressure could be due to a leak
  • Listen for unusual plumbing sounds, eg the sound of water running when all taps and appliances such as dishwasher and washing machine are switched off
  • Outside, look for constant damp patches on paths or driveways, or unusually lush vegetation.

What to do about a leak

Sometimes a leak is so severe that there is no doubt about its source, for example if you accidentally damage a water pipe while carrying out DIY on your home. Other times, the leak may not become apparent immediately, but you can check for signs using the methods outlined above.

The steps for dealing with a leak are largely the same, although in an emergency make the plumber your first call. However, if the leak is not causing any immediate damage, eg if it outside, you will not need to drain the system and may wish to call your insurance company first as they could require you to use their approved contractors.

  • Switch off water at the stop tap. This is often under the kitchen sink, but there may be an additional stop tap in the loft or airing cupboard. Watch WaterSafe’s guide to locating and turning off your stop tap
  • Turn on all cold water taps to drain the system, which will help reduce the damage, and turn off the central heating
  • Switch off the electrics if there is a risk of water damage
  • Call a plumber – you can find a plumber you can trust via the WaterSafe website
  • Check your home insurance policy as you may be covered for the cost of repairs. If you are, give them a call.

Blocked gutters can also lead to water damage. See Aspect.co.uk’s guide to unblocking a gutter here.

If you are a tenant

If you are living in a rental property, instead of calling a plumber, call the emergency number you were given by your landlord or letting agent.
