adding utility sink to basement

hello all,

plumbing newbie pretty much and i have a hard time keeping track of all the names of the different couplers / elbows etc.

would like to add a utility sink next to the washer in the basement. can anyone sketch me a diagram of how they would run the drain and vent plumbing and tie it into the existing washer drain pipe and vent?

the existing drain pipe is a 1 1/2" copper pipe that comes off a 45 branch off the main soil pipe, is there a name for a coupler i could use between the new pvc and the copper? thanks in advance

Laundry Tray

I see your post has been around for a few days without an answer. One prob. could be that there is not enough info.

I assume the wash machine connects into a stand pipe?

How high is the drain from the floor, to center line.

Where is the vent located in relation to the stand pipe?

Where do you plan to put the laundry tray in relation to the stand pipe?

Connecting copper to pvc is the only one I can answer, use either a Fernco or Mission coupling.

As far as posting sketches can't do it with the info, plus I don't know how. it might be better for you to post a sketch of what you have

thanks for the reply shacko, i have been searching around and think i have the info i need, the layout will be quite similar to what is in this schematic

i was wondering if a vent line is needed for the washer but i guess not.

that would be just fine if the proper fittings were used in the proper orentation. a sanitary tee can not be laid on its back or side. a wy+1/8th bend can not be used to go from horizontal to vertical
