The ABS stack is the main waste stack in the house. There will be a trap to where the washing machine will be installed. ABS is not so readily available in my area. I dont want any issues with the so called green universal glue. Since the house is 30+ years old, everything was done with ABS and I would like to make the washer drain transition to PVC but keep the stack I need to know what is the appropriate way to do this? This is a basemernt hookup, and all other drains, tub, shower, toilet, are from above from the first floor. The venting is all done from upstairs to the roof and not accessable from the basement. I have just bought this house, and the old washer hookup was done with a 1-1/2" ABS trap connected directly to the stack, and just used a vented grommet thing over the short washer standpipe. There was no other vent. I want to move the washer about 8 feet away from where it is now, but still in the basement, for logistic reasons. For venting, will an AAV be ok?
So will a 3"" Fernco T fitted over both ends of the stack be the way to go, or can I use the method shown in the sketch? If none of the above, then what is the way to go to getting the washer hooked up proper?
My apologies for the "cartoon-ish" drawing. It was only intended to show the the area of the T where I am most intreseted right now.
