Thanks. For slope you need a carrier that the height of the barrel can be adjusted. The watts carrier from www.bimobject.com/en-in/watts/product/carrier-isca-101-d-t can be adjusted. I believe the connectors have to be checked to "Slope Adjustment" and Sanitary to make it work. This guy kzbin.info/www/bejne/iIKnkKCohrZ3e5o has a good video about this. For me personally I realized it is a waste of time to do the slope for a bathroom cores.
