A few things to note:
- The "image" you were trying to attach is a .pdf file--those don't attach as images
- If that PDF is a Thor plumbing diagram..don't publish it (its Thor intellectual material)
- The best time to drill a hole in the black tank is when you first get it (provided the transporter didn't use it)
- On all the Axis/Vegas units the shower goes to grey and the bathroom sink goes to black
I had the dealer install a Tornado flush kit on ours before we picked it up (let them drill the hole).
