Agile thanks for the reply appreciate it and another source suggested the Worcester parts centre as well and have acquired a valve for £80.
As for the rest well the house was lived in for 10 years before a job move required me to move to another part of the country so idea that rolling in...
I have a problem in a house I own and rent out.
The Corgi engineer has suggested that as the above valve is unavailable I should just replace the whole bolier. Not something i can afford to do nor really want if I can replace the valve easily.
Could anybody guide me to any suppliers out...
