Avoid Frozen Water Pipes – Don’t crack up wrap up!


Damage caused by freezing water and leaking or “escaping” water from tanks, pipes, or heating systems is covered as standard under most contents and buildings insurance policies. Damage to the pipe itself is also usually covered under buildings insurance.


Prevention – try and get prepared in advance of cold weather

  • Lots of lagging – One of the main causes of freezing pipes is lack of lagging – so anyone attempting to do a bit of plumbing themselves, should bear in mind that pipes and tanks in the loft, or anywhere else liable to freeze, need to be properly lagged.
  • Insulate on top of pipes – Insulation should be laid on top of pipes rather than underneath them, as insulation laid below the pipes will prevent rising heat reaching them. Wrap up water tanks and cisterns in insulating jackets.
  • Keep your home warm whilst you’re away

If you are going away for a few days or weeks – leave your heating on at a constant low level, this will keep water in pipes at a constant temperature and means they should not get cold enough to freeze. Also, remove the hatch to your loft so that warm air can circulate while you are away.

(This may appear a little extravagant, but it might mean the difference between a ruined home or a dry one when you return from your break)

It is also worth getting friends or family to check on your home while you are away, since a problem spotted early could mean damage is minimised.

  • Find the stop cock – Before cold weather arrives, find your main stop cock and make sure you can turn it on or off. It’s generally found underneath your kitchen sink. There should also be an access point for a stop cock outside your home (normally near your driveway) so if all else fails you can turn off the supply there.
  • Check the taps – Repair any dripping taps and don’t forget to insulate outside taps in your garden or garage (or turn off the water supply to them altogether).

Do you already have frozen pipes?

  • If taps aren’t working, showers aren’t running and you have problems with your heating it could be you have frozen pipes and it’s likely you will already know about it!
  • If you’re not sure make sure you check all the taps in your home, especially those hidden away outdoors or in the garage, are they running freely? And what about water fountains and features in the garden? It could be they have frozen and you didn’t even know!

Can I prevent them bursting?

If you have a frozen pipe that is accessible try gently warming it up with a hairdryer. At the same time turn on the tap or water supply to that pipe EG the tap or shower and keep it running. Leave the tap on until the water starts running again.

If the worst happens ….

What to do if a pipe bursts:

  • Turn off the inside stop tap  and boiler.
  • Use towels to soak up escaping water or put a bucket beneath the burst.
  • Switch off any electrical items at the mains. Remove plugs from sockets where water may have got into them.
  • Turn on taps and flush toilets to drain the system.
  • Once drained turn the taps off.
    If pipes have burst turn off the water at the main stop cock – by turning off the water you will reduce the amount of water which can escape and so minimise damage to your home. Switch off central heating and any other water heating installations at the same time to avoid further damage and open all taps to drain the system.When cold weather is due to set in, be extra vigilant as just one burst pipe in the loft can mean water gushing through your property ruining furnishings and belongings along the way and in some cases bringing ceilings down.

How to Thaw Frozen Pipes:

  • If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Likely places for frozen pipes include against exterior walls or where your water service enters your home through the foundation.
  • Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
  • Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping pipes with towels soaked in hot water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device.
  • Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible, or if you can not thaw the pipe, call a licensed plumber.
  • Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.

Do not try to thaw out pipes using a naked ame such as a blow lamp! Instead, use a hot water bottle or a hairdryer, but take care, there may be a burst pipe that could spray water as it thaws.

Caution! Water and electricity don’t mix!
