Happy Thanksgiving. It's not starting out too goid at MIL'S house. The kitchen drain is plugged. Arggg. Plunger does no good. She doesn't have a snake. Dual sink and both are plugged so it's down the line somewhere.
This happened in our kitchen sink, dual sink that came down to one line, was grease in the trap from drained meat (a no-no on a septic anyway), wouldn't plunge, trap was solid grease. Good luck!
