Water traps are a waste of time. There, I said it!
I hate to admit that, since I used to be a water trap salesman, but the truth is that they don't work on our systems!
To make the water separate from the air coming out of your compressor, it needs to be cool. Most people mount their compressor and tank right next to each other, which means that the air is still warm when it passes through the separator. It might get some of the moisture, but it won't catch it all!
So, unless you have 10-15 feet of line from your compressor to your air tank, water is still going to get into your system. At that point, what's the use of running the separator in the first place?!
My recommendation is to run a tank that has an internal coating to prevent corrosion (or a stainless or aluminum one), and just drain your tank occasionally. Obviously, if you live in a humid climate you'll want to drain it more often than if you live in the desert.
But save that 15 bucks you would spend on a water trap towards other parts!
