Europa-List: Weeping drain valves

[Paul McAllister <paul.mcallister@qia.net>]

Hi All,

I am having trouble with the spring loaded drain valve on the bottom of my 
Gascolator.
It seems that the smallest amount of crud underneath the "O" ring causes
it to drip and the only way I can clean it is to remove it, wash it out with
alcohol and a tooth brush.

Does any one have a recommendation of a better valve or a way of cleaning it 
without
removal.

Thanks,  Paul
