Indian seat will be connected to the drainage pipe by using an ‘S’ trap or ‘P’ trap. This trap will avoid escape of bad order from drain line by a water seal. Water seal of the seat will be maintained by the trap. But in water closets, the design itself will maintain a water level to seal the bad order escape from the drain pipeline. The Indian pan is available in many different names as squatting pan, Orissa pan and also Asian pan toilet.
