Good evening. I am a Hermit-Nun living alone atop a remote mountain miles from a town or vllage, and cannot get a plumber or handyman at any price. My kitchen was flooded; I tracked it to where the kitchen sink water exits. It has always been a "slow" to empty sink( plumbing was all brand new less than three years ago) and the flood seemed to start when I used the plunger to clear the sink. Does that make sense, please? I am sure it is not a big job, but my skills are every limited and the space where the water is coming from is very narrow indeed. It floods simply when I use the sink; learned that by trial and wet error(a) is this a job an amateur with very few tools can fix, and (b) am I right that it is JUST the kictchen sink water that uses that outlet, and not the washing machine? Awful thought! I imagine that there is simply ( !) a blockage in the pipe that somehow shifted along? So grateful for advice; thank and bless you.
