An Indian water closet (WC) with a flush valve is a type of toilet commonly used in India and other parts of South Asia. It typically features a squatting pan, which is ergonomically designed to promote a natural squatting position, aiding in better bowel movement.
The flush valve is a crucial component that controls the flow of water used to clean the pan after use. Unlike traditional cistern-based systems, the flush valve is directly connected to the water supply and is operated by a lever or push button, delivering a controlled, high-pressure flush.
This system ensures efficient water usage and minimizes maintenance, making it ideal for public restrooms and high-traffic areas. In architectural design, incorporating an Indian WC with a flush valve requires proper floor slopes for drainage, adequate ventilation, and accessibility considerations, ensuring hygiene and ease of use while optimizing space.

An Indian WC with flush valve in construction involves several key components and details that need to be carefully considered during installation. Here’s a descriptive breakdown of the drawing without using an image:
Squatting Pan:
- The Indian WC pan is typically ceramic or porcelain and is embedded into the floor.
- It has a sloped surface leading to the trap to ensure smooth flow of waste and water.
- The pan is set at floor level, with its outer edges flush with the finished floor surface.
Trap (P-Trap or S-Trap):
- Positioned directly beneath the pan to create a water seal, preventing odor from the drainage system.
- The outlet pipe is connected to the main soil pipe, usually with a diameter of 100 mm (4 inches).
Flush Valve Installation:
- The flush valve is mounted on the wall, typically at a height of 1.0 to 1.2 meters above the floor.
- It is connected to a high-pressure water supply pipe (usually 25 mm or 1 inch in diameter).
- The outlet pipe from the valve leads directly into the rear of the pan, ensuring a forceful flush.
Water Supply Line:
- A concealed or exposed water supply line runs vertically or horizontally from the flush valve to the nearest water source.
- An isolation valve is installed along this line for maintenance purposes.
Floor and Slope:
- The floor around the pan slopes gently (about 1:50) towards the pan to direct any spillage into the pan.
- Waterproofing is done beneath the flooring to prevent seepage.
Ventilation and Access:
- Adequate ventilation is planned through windows or exhaust fans to ensure proper air circulation.
- Access panels may be provided if the flush valve or piping is concealed, allowing for maintenance.
Finishing:
- The floor is typically finished with non-slip tiles, ensuring safety in wet conditions.
- Silicone or cement grout is applied around the pan edges to prevent water ingress.
This setup ensures durability, ease of cleaning, and efficient water usage.
