Frozen Pipes/Condensate pipes

We are currently experiencing a cold snap , and this can impact the condensate pipes on boilers and in some cases can freeze pipes within homes.

A condensate pipe carries condensation from your boiler to your outside drain. It’s usually a white or grey plastic pipe that travels from your boiler through the wall directly outside where your boiler is located. During cold weather, the condensation in this pipe may freeze and cause a blockage which could result in your boiler failing to operate.

This can be cleared using the following steps

  1. Confirm the condensate pipe is frozen

Depending on the make and model of your boiler, a frozen condensate pipe may be indicated by a ‘fault code’ or warning light on the boiler’s display. Gurgling or bubbling sounds coming from the boiler or the condensate pipe are another sign that the condensate pipe has frozen.

  1. Locate the blockage

The pipe is probably frozen at its most exposed point. This may be the open end of the pipe, or at a bend or elbow. Running your hands over the pipe until you find a section that feels colder than the rest should help you identify the blockage quickly.

  1. Use hot water to thaw the pipe

Using a jug or watering can, pour hot water along the length of the pipe, repeating the process until the pipe has thawed (do not use boiling water as this can crack or damage the pipe). If you’re using a kettle, make sure to cool the kettle for at least 15 minutes once it’s boiled. Alternatively, you can use a hot water bottle or a heat pack to slowly defrost the pipe.

  1. Restart your boiler

Once the frozen section has been melted and cleared, check your boiler manual for instructions on how to reset the boiler correctly. Your boiler should now restart.

  1. Not fixed? Keep trying

It may take several attempts before your boiler restarts, but if it doesn’t, you may need to call our repairs line for an engineer to attend.

If you do not have running water it is possible that you may have frozen pipes and you should firstly ensure the property is being heated to prevent pipes from freezing.  If this does not help please call our repairs line on 0800104105 during working hours or our standby operative on 07721 889618 outwith working hours.
