Dave,
It sounds like you do not use your valve on a continuous basis, so
perhaps the carbonic acid doesn't have a chance to work on it. I have
gone through 2 of those cheap $1.50 valves already (2 different brands
and designs). Each lasted only a few months before the rubber diaphram
dissolves.
Anyway, after George suggested the Dupla bubble counter with valve, I
went to the Pet Warehouse catalog and found that Dupla also has a $15 CO2
check valve. I think I'll get that one (I already have my own home-
made bubble counter).
