I recently sold one of these and the buyer tells me it's dumping the co2 as soon as the bulb is screwed in.From what I can make out the valve in the magazine is sealed with no replaceable parts apart from an oring.
If it's the actual valve what can be done?,apart from a complete new magazine will any other type of valve fit to replace the original one so it can be serviced when needed.
The buyer has asked me to source the parts to stop the leaks but I'm struggling to find anything suitable.
