This unit is heavier and wider than the older model Septic Assist.
I had to cut the hot water stop back to the wall to accommodate the unit.
I used a brick to lift the unit, so I could turn it onto the ISE flange.
I would recommend a second person to lift the unit for an easier install.
I’m not a a fan of the hose clamp tailpiece. I prefer the older model tailpiece with the screw flange. All in all, a quiet and heavy duty disposal.
