2 Soil Fittings - Water Closets, Urinals

2 Soil Fittings

Soil fitting is one type of sanitary fittings, following 2 soil fittings (water closets, urinals) are described below:

1) Water Closets(W.C)

A water closet is a sanitary fitting designed to receive human excreta directly. It is connected to the soil pipe by means of a trap. Sometimes, the room in which it is installed is also referred by the term water closet. 

Two types of water closets are commonly used these days. They are:
  1. Indian type water closet.
  2. European type of water closet.
The Indian type W.C has a squatting pan 450mm to 675mm in overall length and 400mm to 500mm in height.

The pan is fitted with a P or S trap, which is then connected to the soil pipe. It is usually made of porcelain. The trap has an opening for fixing an anti siphonage pipe or a vent pipe.


The pan has a flushing rim to spread the flush water. This W.C requires at least 10 liters of water for proper flushing. This type of W.C is largely used in Indian houses.

The European type W.C has a porcelain pan 500mm to 600mm in overall length and 350mm to 400mm in height. It is one piece construction in which the pan and trap are not separate. A cover is provided at its top.
