I recently went under my house to do some plumbing for a bathroom remodel and discovered a huge amount of moisture in the crawl space. I believe that to be largely weather related but upon inspection I did see that the ac coil condensate line had a problem.
As you can see from the attached photos (the top 2 are the "before"), the trap on the line running from the coil pan had broken. The installers used a rigid piece of clear PVC on the lower side of the trap and flexible PVC tubing on the upper side. The rigid piece broke where it was connected to the unit's 3/8" drain tube (likely either from age/brittleness or maybe it froze when there was condensate in the line during winter?).
Being the inexperienced beanhead that I am, I thought that the trap was a lazy way that the installers had connected the drain tube to the drain line running outside. When I redid the drain line, I removed the trap and straightened up the run of the drain line (removing the 90 degree turn shown below). After doing research on this (why didn't I do research BEFORE???) I believe that I have absolutely GOT to have a trap on this drainage system.
Please confirm what I am thinking, and confirm that my "after" pictures (the bottom 2) will result in disaster if I don't reinstall a trap.
Thanks in advance and please go easy on me even though I am an idiot.
