Yes mate always do. It is definitely the gas valve. 12.5 is a right joke. It must have been a Friday job.Do you cut a test pint in under the boiler ?
That's quick service
I would say it probably was if you had a test point in before the boiler.I had one at 15mbar awhile back and they said aslomg as gas rate was good it's ok. Starting to think it could have been faulty. Think the service is due soon so will have to make sure.
