Right, I finally bit the bullet to sort out my leaky Angram CO pump, which had a persistent drip running down the piston rod, underneath the glass cylinder and was sucking air for the first 1/4 of the pull.
I picked up a seal kit from the very helpful people at Angram North Yorks, which included a 'bottom gland' assembly, which in turn contains the graphite 'O' ring that seals the piston rod, which I suspected was the cause of the leak.
After some much needed reassurance from the chap at Angram I went home and set about stripping and cleaning the cylinder and all associated bits.
It was pretty straight forward (even for me) although I took care to note where each piece went in readiness for re-assembly.
The internals (particullarly the glass cylinder, block ends and large grey 'o' ring seals) were pretty gunky, so the old seals were binned and the cylinder and the block ends given a dam good clean.
I managed (after a bit of persuasion with a screwdriver) to pop the gland seal assembly out and the new one located easily with a reassuring snap!
After cleaning I took care to aline the glass cylinder correctly, ensuring that both ends were properly seated on the 'o' ring before nipping up the bolts on the bottom 'block end' (apologies...don't know it's proper name) before finally fitting the new, pristine white polystyrene jacket and sliding it all back into place.
I am now delighted to report that there is no leak whatsoever and also there is no air being sucked in, which results in beer (or water in the test) being drawn, right from the moment the handle is pulled...a very satisfying 1/2 pint pull (and it takes some pulling too
)
I'm certainly no expert now, but I do feel more familiar with the internals of the Angram CO pump, and would encourage anyone fretting about tackling a leak to grasp the nettle and get stuck in. The results in my case have been truly worth the effort and I can't wait for the postie to bring me a sparkler so I can draw some dark mild that is sitting in a cornie as we speak!

Let me guess -- you nicked it from a church?
A friend was contracted to clear the building ready for converting into flats and he offered it to me as he knew I was building a house, so decided to use it to serve the correct spirit finally managed that 9yrs later.
