it seems like everyone has a different opinion of where to put the water trap. i like in ky we have cold winters and i want to know the best way to keep my valves from freezing. the valves will be under my hood (just doing front for now). i already have a 3/4 water trap with a t after it going to two 5/8's lines. is this over kill? and should i take it back and just buy a 3/8 and put it before my tank (or will to much condensation build up in the tank)? thanks for any help
