Hi Folks
I am having a bit of a problem with leaking pipes around my combi boiler. What should I do?
Dave
Hi Dave,
A leak in the pipes can cause the whole boiler to stop operating. This means one of the pipes was punctured or poorly installed and it will also release a hissing sound when the boiler is on and being used. The pipework may need to be replaced but for a temporary fix, you will need to close the cold water stop valve that connects between the draw-offs and the boiler.
The Vaillant boiler does not come with a cold water stop valve but it was probably provided and installed when installing the boiler. The boiler won’t operate as long as the water is stopped. Contact a heating specialist company to check the pipes and maintain the problem.
