I have checked mine regularily for the first 10 years of ownership.
99% of my fuel comes from my own tank, and it gets separated, and 
double filtered before it gets into the car.  In the life of the 
vehicle (we're working on the second light-second), I haven't drained
more than a tablespoon of water out.  I've never found any in the 
fuel filter, ever.  

I stopped checking a couple of years ago.  Why break it?


ps: Don't think that no water in the drains, means the fuel is 
bone dry.  Diesel oil will retain a certain degree of moisture.  
So it's possible that there may have even been more precipitated 
water in the system than I drained.  However, unsaturated water
will simply pass with the fuel into the combustion process, where
it has a negligible effect.  We're talking small amounts.
