Need a little help here
This was a second floor washing machine drain pan. I scoured my code books and the internet and could not find anywhere that this was a requirement and I could not find much info on a properly installed drain pan. This pan had a little pipe welded on to it. A hole was drilled in the floor. The pvc ran all the way into the crawlspace. I know it should not drain into the crawlspace but where else would it go? Should it be installed to drain into the homes drainage system? outside?
