Hello?
Expert:  Brian replied 1 year ago.

Hi can you confirm the make I have never heard of a Vailsbr boiler.

You will need to bring the pressure up whatever the make, and this is usually done by using a filling loop that is normally situated under the boiler it is a silver braided flexible pipe and usually has a valve each end, open both valves and bring the pressure up to 1 bar.

Sorry - typo - it's a vaillant
Customer: replied 1 year ago.
There is a braided pipe but it's inside the boiler casing
Expert:  Brian replied 1 year ago.

some models have an inbuilt filling loop like this.

There is no filling loop showing on this boiler so it is possibly lower down I would suggest following the pipework if possible

Customer: replied 1 year ago.
Ok here's the pipe work below
Expert:  Andrew Smith replied 1 year ago.
Do you have a silver flexible pipe attached to the pipework under the boiler?
Customer: replied 1 year ago.
No but there is one visible just inside the casing?
Customer: replied 1 year ago.
It appears to be connected to the black disk with the cross on it
Expert:  Andrew Smith replied 1 year ago.
The third pipe from the right is the cold inlet, there may be a filling valve there?
Customer: replied 1 year ago.
As I look at it this way (from underneath) the third pipe says gas inlet?
Customer: replied 1 year ago.
Is the black disk not the cold inlet valve?
Customer: replied 1 year ago.
There is a braided pipe going into that
Expert:  Andrew Smith replied 1 year ago.
Can you upload a wide picture of it?
Customer: replied 1 year ago.
Here you go

Expert:  Andrew Smith replied 1 year ago.
The black disc is a drain point for the non return valve.
Can you see the other end of it?
Customer: replied 1 year ago.
It's attached to the second pipe in from the left in the image I sent you
Customer: replied 1 year ago.
Sorry that's second from RIGHT
Expert:  Andrew Smith replied 1 year ago.
Ok, into the central heating return - that's good.
There should be a valve on each end - perhaps if you drop the front cover down?
Customer: replied 1 year ago.
Here's the cover off
Expert:  Andrew Smith replied 1 year ago.
I cannot see a valve?
Is it concealed around the back of the pipe and I just can't see it?
What about at the other end near the non return valve?
Customer: replied 1 year ago.
Difficult to say -.not sure what I'm looking for
Expert:  Andrew Smith replied 1 year ago.
Either a lever or a screwdriver slot valve
