Step 2 - Locate your pipe
It’s time to brave the cold and go outside to find your condensate pipe – it’s usually a white or grey plastic pipe coming out from the back of your boiler to the outside wall of your property. When installing a boiler there’s always a large amount of piping that is exposed to outdoor conditions, when the weather turns cold the pipe could get blocked due to the pipe freezing.
The condensate pipe is an important part of your boiler as it discharges wastewater vapour from the system – if the pipe is blocked it will force your boiler to shut down for safety reasons.
Step 3: Thaw your pipe
The easiest way to deal with a frozen condensate pipe is to put it in contact with warm water. A couple of jugs of warm water poured over the exterior of the pipe will melt the ice within. Make sure you don’t use boiling hot water, as the rapid change of temperature could crack the plastic pipe.
If you don’t have a jug on hand, feel free to use a hot water bottle or warm flannel.
