Let's compare.
The flounder I made for dinner was pasty and my black beans were very salty.
Mrs. WI took a shower and upon completion informed me that the tub wasn't draining.
I went in to see if the drain plug was stuck, or maybe if there was something there in the drain, and saw that the tub was filled to the brim.
I examined the trap and was perturbed to discover that there wasn't a clean-out plug there, but there was one in the main line. - removed that plug and found that the bottom 1/3 of the 20' line had a nice even layer of shite.
I powerwashed it clean and, thankfully, it all ran outside to the septic tank. But that didn't explain why the tub wasn't draining.
Back I went to the tub trap and found that there was a 4" piece of brass pipe making the transition from the tub to the pvc trap. I removed it and found it to be clogged with hair and soap. Those of you that know me well, know how much I despise hair in the sink, so you can imagine how thrilled I was. at least it was partially disenfected because Mrs. WI pees in the shower.

. At any rate, I spent the next 30 minutes scooping hair and soap bits out of the trap through the tiny gap (using a teaspoon), and flushing the line clean with a garden hose.
Mind you, it's 40 degrees out and I'm spraying water all over my basement with a hose and a powerwasher.
Feeling any better about your day yet?
Well consider this...when I typed all of this out, I deleted it by pressing the wrong button!
