I have a Worcester Bosch 24i thats slowly losing pressure, and I think I've traced it to the pressure release valve (large red knob). The pipe from the valve has signs of water down the external wall.
Wondering if there's anything fixable on the valve or is it a new one? Its tight in a cupboard and is going to be a bugger to get out.
