Single family 4+ baths. Will have two 4" building drains coming together and then out to sewer. Original sewers around here are sometimes 6" terracotta. We'll have not only sanitary drainage but also gutters (allowed by city) on 5000 SF house (1200-1500 SF footprint)
Thoughts on 4" vs 6" from building drains wye? Guess I'm looking to find out if it's a bad idea to have 6", which I lean towards.
