Hi .you need to top the water pressure up
There will be a flexible hose filling loop somewhere. Usually it is under the boiler on the pipe work , sometimes its built in to the boiler ,depending on the model
Its a fairly easy thing to do once the filling hose is found
That's probably the the model ,dobyou know what manufacturer?
Did you mean baxi?
Ok . did you mean to write baxi?
Ok . under the boiler can you see a silver flexible hose ,on the pipework ?
Ok , give me a minute to check the manual to see if its built in , please
Hi , its not built in , so it will be somewhere on the system .
Can you upload a photo of the underneath your boiler?
Yes , it will be safe
Why did you rate me poor?
If you are worried about it ,just turn the power to it off for now.
