I was just trying out the venturi to see if it actually would pull the slight black tank odor out a little better. It does seem to make a difference but we are also out of the worst of the summer heat too.


More curious in what the extra vent would be. We have three tanks so why 4 vents???What is the extra one for?


I have heard that the flat one is an attic vent. So there is actually a space between the roof and interior ceiling? I figured there wasn't any space there or if it was it was full of insulation?
