Hey everyone,
I recently moved back into our family home that was built in the 1950s and I'm thinking about relocating the laundry room. The new location I am considering is in the basement under the kitchen and I thought it would be easy to tie the washing machine drain into the kitchen sink drain pipe. It is mostly 1.5" copper that runs from the cleanout in the basement floor up to the kitchen, but there is also a piece of cast iron pipe between the copper and the newer abs under the sink that was probably done by my late father.
My first thought was to cut a section out of the copper and splice in an ABS wye for the washing machine drain with some flexible fernco type adapters, but then I started wondering if I should just remove all the copper and that short piece of cast iron pipe. The copper is threaded into the cleanout in the basement floor, so if that threaded piece could be removed maybe there's a threaded abs adapter that would fit in there instead. Or maybe just leave a piece of copper at the cleanout and attach some ABS above that.
Does removing all the copper make any sense at all? I would like to keep the cost down on this, unless there's some real benefit to ripping things out and starting over. Which leads me to the next question.
The other problem I noticed is the kitchen sink does not appear to be vented. The only vent stack is at the back of the house where the bathroom and and the laundry are, but the kitchen is in the front of the house. There is also a window over the kitchen sink. I could perhaps add an AAV under the sink, but I think they're supposed to be above the sink, which isn't possible here. So not sure that's a good idea. We've lived in this house since the 60s and I'm not aware of there ever being any problems with the way this sink is plumbed.
Here's a few pics. Any advice on adding a laundry drain and ensuring everything is properly vented would be much appreciated.
