one main reason for making sure rite size pipe is always if you have to large of pipe the flow of material and water is not great enough to keep it cleaned out inside fare ..but this normaly is for smaller inside line 2in or 1&1/2 but if you want to use 4 in pipe you can with in code use it on main no problem just cant go to small such as 4 toilets on large home and use 3 inch pipe is no way ok ty
