boiler All aspects of plumbing questions and answers, help, tips and information

[rfroud]

My Worcester Bosh combi boiler shows that there is no pressure in the system. When I top up to the recommended pressure it starts to go down almost immediately as if there is a leak. I have looked for a leak and cannot find one. Where is all that water going?
Help Please

Er, out of a leak. The thing is you just haven't found it yet.

Check the condensate drain for a dribble when the boiler is off, and the pressure vent outside the house. If they are both dry, then the leak must be in the heating pipework somewhere.
