Condensate drain line

Anyone have a diagram of a A/C condensate drain line with a trap?
If so please e-mail to me,or.r_gc.r_pw.,cf.osb&ion=1&biw=1599&bih=804&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi

Good one Thanks Bob

Thanks Bob

The builder said it needs no trap, as a matter of fact only drain lines 2" and larger need a pee trap. I just shook my head and walked away.
