Hi,
I have a question about everyone's *favorite* topic, adding a standpipe for a washer drain.
Right now, I just have the washing machine draining into the sink, and I'd like to have a cleaner look with the standpipe.
Here is a schematic of the setup right now:
All the DWV lines are black 1 1/2 inch ABS.
Now, I guess the first question--is the current setup considered correct?
I know these should probably be 2 inch lines, but all this was done, I assume, when the house was built, in 1990.
What i am thinking of doing is this:
Tie the standpipe into the line that goes to the wye, so that the standpipe will drain below the laundry tub, and venting off that same line.
San tees for all new connections as needed, put the standpipe at the correct height. Still use 1 1/2 inch ABS (don't think I can tie 2 inch into 1 1/2 inch, right?).
I would tap the standpipe vent close to the current stack, to avoid running lines over the laundry tub--all this is in an exposed area of the basement, and i don't want extra lines running over the laundry tub, if I can avoid it.
Both the drains would be at about 18 inches off the floor--in the diagram, it looks like I have the standpipe line higher, but that was just for purposes of the sketch. (Also, the washer is in front of the standpipe)
Is what I have in the second diagram correct? Should I tie into the other line instead, or do I need to find another line altogether?
Let me know if I am way off base, or if there's any other way to do it.
I am not offended with any advice given, just want to make sure I do stuff right.
Thanks,
Jerry
