This weekend I replaced a drain stopper and all the hardware down to the p-trap, keeping those parts original.
After connecting everything I ran the water for about 10-15 minutes while I cleaned up. There were no leaks. Later that night I looked under the sink and noticed a pretty large puddle. We left the home after my fix so I knew it wasn’t from us using the sink. We did however run the dishwasher. I noticed there was water on the compression nut that secured the stem to the p-trap. I tightened the nut.
Today there was no leaking all day until we ran the dishwasher again. It was considerably less, but still a leak. Again the water was popping around the compression nut. I tightened the nut some more.
Why would the dishwasher be causing my bathroom, clear on the other side of the house, to leak? Is that a sign of a clog somewhere else in a line on the way out to the main?
Some other interesting things we’ve noticed about our plumbing that may or may not help diagnose this problem:
- Whenever we start the dishwasher, a really foul smell comes up from the disposal.
- We have a “if it’s yellow let it mellow” policy for flushing. A different bathroom (the kid’s) starts smelling really bad after it hasn’t been flushed. I know that sounds obvious but no other bathroom in the house has this problem.
