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.
