Kitchen sink draining really slowly. Had a sort of cumbersome ABS set up for trap assembly - double sink with disposal. I got it off and there was a small artist's paint brush, maybe 5 inches long protruding up from the first elbow. Add to that the long lateral piece had next to no slope, no surprise that it had a gelatinous mass lodged. Removed that with garden hose water pressure, then I took the tailpiece off and up inside the odd basket was a bunch of slime grunge. I'm guessing weeks of slow draining provided for a growing culture. You could see it from above also. The basket gave no sign of easy removal. Almost looked glued on. I was trying to fish the stuff out with little luck. There was no sprayer in this sink. I have a garden hose sprayer attachment that's useful, only has the jet setting, but not the old twist type, has a handle, makes for tidier indoor use. These people had a good garden hose within range, so with their approval I hooked it up, no leaking, brought it in, and dooshed the basket out good and proper, complete with gnarly stink. Not only is this a weird looking basket, I swear it had more room inside for slime to hang out. Maybe it would have twisted off but it was 7 pm, did NOT want to break the sucker and need to make a mad dash to the Home Depot about 20 minutes away. The strainer looks normal enough, not sure if they are a tandem oddball unit. Good for me I got the whole thing working in fine fashion. Anybody seen this before?
