Everything will be 3'' DWV except for smaller fixture outlets. Clean out will be placed upstream of toilet and below the vent. Horizontal and vertical turns will be long sweep 90s and all other connections will be wyes. Is there sufficient venting and how would you connect a dishwasher to the system? Do dishwashers need traps? I may just leave the washing machine and laundry sink as is. But I also wanted to know if where they are connected to the main drain pipe is okay and if they need a vent pipe. If they do need a vent pipe are the planned connection locations okay? http://ift.tt/2minlNk via /r/DIY http://ift.tt/2lSSPgK
