So last night I did send some butternut squash skin down the disposal and when late last night the sink did not drain I figured I knew why. So first I disconnected the disposal expecting to find the clog right there and no... I have a 50's built house and the trap for the kitchen is in the basement. I opened the trap.... water came spewing out from both sides of the trap. Seemed like it was under pressure with the force it came out. Poured some water down the sink to see that that section was clear. I snaked the other section all the way into the main sewer pipe...three times. I know it went all the way into the large sewer drain. Put the cap back on the trap.. go to fill the sink and clogged. The larger sewer pipe is also fed right on the other side of the pipe from the bathroom. That drains fine. Hmmm...
Over at the hardware store the only thing they can think of is a clogged air vent to the roof. I am in the northeast.. ICE ?? The kitchen sink does not have it's own vent. Maybe the bathroom has it's own but I don't know where it would vent. If there was a clogged air vent would I have other drain problems from the 3 items in the bathroom.. Mystery ?? All copper pipes.
