Sanitary Syndicate Interview Questions, Process, and Tips

I have worked with various types of pipes including PVC, copper, PEX, and galvanized steel.

• PVC pipes are commonly used for drainage and water supply systems due to their affordability and durability.

• Copper pipes are often used for water supply lines because of their resistance to corrosion.

• PEX pipes are flexible and easy to install, making them popular for residential plumbing.

• Galvanized steel pipes are strong and dura

The main difference between 50 dia and 65 mm dia CPVC pipes is the diameter size, with 65 mm dia pipe being larger.

• 50 dia CPVC pipe has a diameter of 50 mm, while 65 mm dia CPVC pipe has a diameter of 65 mm.

• The 65 mm dia CPVC pipe can carry a higher flow rate compared to the 50 dia pipe.

• Cost of 65 mm dia CPVC pipe is usually higher than the 50 dia pipe due to the larger size.

IS Code for CPVC pipe and fitting is IS 15778:2007.

• IS Code for CPVC pipe and fitting is IS 15778:2007

• CPVC pipes and fittings must conform to this Indian Standard for quality and safety

• IS 15778:2007 covers specifications for CPVC pipes, fittings, and solvent cement

A PRV station SLD is a schematic diagram showing the layout of a pressure reducing valve station.

• Include the main components such as pressure reducing valve, isolation valves, pressure gauges, and strainer.

• Show the flow direction and connection points of the components.

• Label each component clearly for easy identification.

• Ensure proper sizing and spacing of components for clarity and functionality.

Costing for installation of 20 mm dia CPVC pipe inside the toilet area can be calculated by considering the length of the pipe, cost per meter, fittings required, labor charges, and any additional materials needed.

• Calculate the total length of CPVC pipe required for the installation

• Determine the cost per meter of 20 mm dia CPVC pipe

• Consider the cost of fittings such as elbows, connectors, and joints

• Include labor charge...read more

The slope for an underground drainage system should typically be 1/4 inch per foot or 2% slope.

• The slope of the drainage system should be at least 1/4 inch per foot to ensure proper flow of water and prevent clogging.

• A slope of 2% is also commonly used for underground drainage systems.

• Proper slope helps in efficient drainage and prevents standing water or blockages.

• Consult local building codes and regulations for speci

The soil and waste pipe should be terminated with a cleanout at the 40th floor and extended to the roof for future access.

• Terminate the soil and waste pipe with a cleanout at the 40th floor to allow for maintenance and inspection.

• Extend the pipe vertically to the roof to accommodate the two additional floors above.

• Ensure proper sealing and support for the extended pipe to prevent leaks and structural issues.
