I got the valve out and disassembled on the bench and its clear how the leak is occurring

There is a diaphragm that is clamped between the valve body and the spring cap - the spring cap has a machined groove for the diaghragm seal to locate in (see below)

With the diagphragm in place the sealing edge sits slightly proud of the spring cap face and when clamped to the valve body achieves a tight seal (see below)

My theory is that by machining a couple of thou off the spring cap face this will reduce the height of the machined groove making the diaphragm seal sit further outwards, thus squashing tighter against the valve body - hopefully resolving the leak...

Will let you know the results when im done
