Practical Notes
! Ensure the flushing inlet and waste outlet dimensions match the connecting plumbing traps and pipes accurately to prevent leaks.
! Prior to installation, visually inspect pans for permissible defects like crazing, warpage, and glaze pinholes as detailed in IS 2556 Part 1.
! BIM modelers should reference the dimensions in Tables 1 and 2 to create accurate parametric families for clash detection.
