Sump pump discharge line - why above grade?
I've watched a bunch of videos about installing basement sump pumps, and I noticed that whenever the discharge line is installed it always goes up, through the foundation wall, then back down into the dirt. I'm wondering why they are never routed through the wall directly into the trench without going above grade. I didn't see an express requirement in Sec 1113 of the building code. Are there practical benefits of this? So, instead of going above grade like this: https://preview.redd.it/5cmap2m5mk0f1.jpg?width=692&format=pjpg&auto=webp&s=84afc077d62b94c0c7c42395a8ee7e10461d342c Going below grade like this: https://preview.redd.it/3i6dkgk4mk0f1.jpg?width=694&format=pjpg&auto=webp&s=fc4201d123f17c8dbe70cfadaffb91e4e121b299 submitted by /u/nycingh [link] [comments]
