I have an old house (1940’s) that I rent out to a family in Amsterdam, NY. Before my purchase of this property in late 2007, someone tried to install a set-up for a washer and dryer. The electric for the dryer had to be changed to code and now, the washer drain stand pipe (always backed up waste water out the top) needs attention. The 2 inch PVC stand pipe is connected to a 1.5 inch metal pipe with no P-trap running straight to the sewer line. I know that I have to install a P-trap to stop the sewer gasses but because I have no way to remove the 1.5 inch metal pipe, I’d like to know if I could somehow reduce the waste water flow pressure from the washer as I believe that is why the water backs up. I’ve snaked the pipe a few times and it seem to be clear. I used a heavy duty “spade tip†snake. Any suggestions?
