Any recommendations for a fitter / technician who can service / diagnose a problem with our Gaslow system in the Redditch / Birmingham area?

Just recently, I have found it very difficult to fill our tanks as the pump keeps cutting out as if the tank is full - when I know it is not. When the trigger is pulled, I am lucky to get a quid or two's worth in before having to give up.

Got me completely stumped as to what is wrong. And, yes, the valve is open!

Cheers
Carl
