Black water tank not draining
Ok. It's me again. I got my toilet working. Now, I've had septic people out twice to drain my black water tank. Once about 6 weeks ago, and again today. Both times they didn't get much if anything. I'm home all day, so I know that tank gets used a lot. Why are they not able to get anything out of it? What do I need to check?
I have an 08 outback Sydney edition
