Drains
Not sure where to start. My Galley sinks are not draining and I was going to pull the p-trap under the sink to see if it was plugged up but then I noticed this. I was checking the led control panel and I observed this.
The back black tank is empty
The back gray tank is empty
The mid black tank is empty
But the mid gray tank reads full - is this why the sink won’t drain. Where can I start to look.
My sewer line is connected and I pulled both levers for black and gray tanks. Is there another lever I missed? Any suggestions would be appreciated
