Drain went from like 20 hours to drain backwashing into my dishwasher. @tk having the drawer means my floor didn’t flood \o/

From there I took apart all the pipes I could. They were clean so I have now used 2.5 gallons of lye.

First gallon was basically enough to get it to be at the rate of a hour glass.

2nd gallon got it to the point of draining fast enough if you leave the sink on it does not back up.

3rd gallon is hopefully gonna make it high speed drain with water vortex level clean.
