Thread: water-less P-trap
09-09-2012, 08:37 PM #1
I remember see a post on the forum a while back about a crazy looking drain line on a trane RTU that ended up being a waterless or self priming P-trap. I think someone even posted a PDF on it. I have an account I would like to try it on due to helpers not priming traps.
If any one has any info or could post a link to the thread I am looking for would appreciate it.
