a/c drain and sink

miguelaraujo

I recently started to remodel a bathroom sink and discovered a 3/4" drain line that was attached to the sink drain line before entering the wall after disconnecting I realized it came from the a/c -is this acceptable in the Houston area ,,When I had the house inspected in November the inspector looked in the cabinet and did not mention it,,if it is not then what is my fix ??

As long as there is a ptrap in the A/C drain line you're good to go!

thanks for the reply -the a/c line comes out of the wall and turns down to meet the 2" drain line between the sink p trap and wall ,for now I connected it to a solvent reducing tee, before it was just a hose with clamps going directly to the sink drain before the p trap

Well if your A/C drain line is tubing, I would just coil it once, that trap will prevent sewer gas from entering your supply plenum.

Now I'm really lost--- what I have is 3/4" pvc s/40 drain from the a/c in the attic--so somewhere between the bathroom and the attic I have to have a p-trap ???
can the line go directly to the sink drain before the p-trap and 2" waste water line ???

In your case there is probably a ptrap already installed at the coil in your attic.
