Sanitary Syndicate Plumbing Engineer 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

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.
