If you are using that type of hard plastic tubing cause that is all you have then cool, but otherwise its prolly more expensive then cheapo aluminum kind. Also building it into your plumbing by that you are trying to inline the actual scrubber which is harder to do then placing it at the end or beginning of the duct work. I have some pretty easy to see pics in my thread which you can find a link at the btm of my posts. there are really good cab/closet pics on this site that should help. At the end of it all remember to have fun, cause it will be. :thumbsup:
