This is a low proximity back shelf type hood. I covered that in the thread already and is covered in other peoples builds as well.
 
Thank you though 🙂

Couldn’t you get that tank between the beams??….That looks like an accident waiting to happen.
I also would have plumbed the waste directly into the tank, if your just a bit out of level on the one side, your going to have problems draining……..

+1  I see problems ahead with tank and plumbing. And I think your hood will need raised or it will be a pain in the back and neck to work!
