How to put in basement floor drains

You're in luck. Floor drains are the only trapped drain that doesn't need a vent,(check local codes). Cut into the main and come off it with a wye or a combination wye and eighth bend. Make the top of the strainer a inch or so lower then the cement so you can slope to it. Good luck, Tom

Is your floor already in place and you want to add drains? If this is new construction please give us the details.
