I would like to install a utility sink in my basement, but wanted to get some opinions about drain connections.
I have 4" cast-iron going out through my basement wall to the city sewer. The cast-iron runs horizontally for a while, then connects to a wye with a 45 going to a vertical stack that goes all the way up the house and through the roof. The other connector on the wye is capped with a cleanout plug. The distance from the floor to the center of the cleanout plug is 24".
I was hoping that I would be able to remove the cleanout, connect a PVC pipe (3" or 4"?), connect to a wye with a 2" or 1.5" and cap the other end of the wye with a new cleanout.
First question, is 24" too high off the ground for a utility sink p-trap to be connect for a gravity drain? I know I can mount the utility sink on blocks to get it raised up, but how high would I need to raise it? Should I consider using a pump instead?
Second question, how do connect the PVC to the cast-iron wye? The cleanout looks like it's screwed on to a pipe that has been fitted into the bell of the wye. If I wanted to use a 4" donut, I would imagine I would have to remove all of the oakum and lead from the bell of the wye. Could I use a donut on the pipe that cleanout is threaded on to?
