an other EDC question!!

ok so my question are these: 1) will a 6 ft 1/2" leader hose be plenty long enough? and 2) where should i look to get a water trap?

I just got a SMC trap from SD all metal have not used it yet but should do its job. I know the plastic ons break. And a 6 ft hose should be fine just make sure you use a good ck valve in line

should i put the Check valve before or after the trap?

After.
