A few questions concerning main line.
What size (3 or 4) should I use for main drain line. Per code, a 3 inch is large enough, but was thinking about using 4". Considering nothing other than performance will going with larger pipe be better or worse?
I have plenty of headroom in crawlspace, SO....is it best to get more fall, say 3% slope verses 2%?
OR what combination of size and slope is best?
Thanks
