Fuel Filters for Dummies

(Shamelessly cross-posted from A-S - because I'm an impatient bugger.. but you probably knew that already!!)

Just wondering if I'm missing something here.. Here's a pic of our fuel filter:

As I see it, there are two main controls - the fuel shut-off valve (yep, I can handle that ) and the drain valve. AIUI, any water in this thing will settle to the bottom and show clear, relative to the yellowish diesel above it (in the pic above, you can just see the line above the bottom of the bowl).

Opening the drain, I get pretty much straight diesel out and the yellow/clear level doesn't change. Upon closer inspection, it seems that, from the location of the bleed point in the chamber, there needs to be about 1" of water in this thing before I can drain any out with the bottom bleed...?

My questions:

1. The drain plug is extremely hard to close off without it leaking diesel. Is it supposed to be this hard to shut off, or am I missing something?

2. Is there supposed to be water in the bowl at all times?

3. If not, how do I drain the water out??
