Recently purchased a house a few months back and therefore purchased a washer and dryer. The washer has been working fine and draining great for the last couple months, but suddenly the drainage for the washer now overflows and spills all over the floor.
It's a 2 inch drain pipe and I haven't had any problems until now. I purchased a 25 foot long 1/4 inch diameter power operated drain snake and was able to thread the snake all the way and came back with no clog.
The water still drains, but just not fast enough. For instance, if I stop the washer during the draining process the water level goes down immediately. As soon as I let it start draining at the 'normal' washer emptying speed it immediately fills the drain pipe completely and then inevitably will overflow.
Any suggestions or help? I've done some serious searching online and can't find any ideas other than a different washer, installing an air admittance thing (but referred to as a band-aid for a larger issue), or switching to 2 inch pipe which I already have. Is it possible, although unlikely, that the actual vent is clogged??? It runs up into the attic and then from there runs parallel to the ceiling for about 20 feet and then straight up through the roof.
I cut out the drywall to take a look and get some pics. The water sounds like its draining really quick but for whatever reason, it suddenly has started this overflowing thing. What could have changed after working for so long that has it overflowing all the sudden??? Pics are attached below. Thanks for any help.
Seriously frustrated at this point.
