i recently installed a new sink/disposer. i had to close the s trap to align the new plumbing to the existing drain pipe.
my question is...after i stop running the water, and it completely drains from the sink i hear this gurgling or popping sound as if air is working its way back through the piping. im not a plumber, nor can i really afford one right now. is this a simple fix or should i start saving now to call the pros in.
thanks for any advice,
