i want use hardi backer in my new basement bath,,i installed a mrj,ready jon system [sewage ejector package]receaced in the floor and the rest of the floor is concrete. should i glue plywood over concrete and the plastic of the ready jon or can i put the 1/2" backer over them instead of over the plywood? the concrete is old and has no cracks, is pretty smooth. the plastic lines up perfectly w/ concrete...any comments would be helpful

thanks ,,keith
