This standard covers the requirements for materials, dimensions, manufacture, workmanship, and testing of pillar taps used for water supply systems. It ensures standard threading, material durability against corrosion, and leak-proof performance for taps typically installed on wash basins and sinks.
Pillar Taps for Water Supply Purposes
Quick Reference Values
Nominal sizes15 mm and 20 mm
Hydraulic test pressure (body)1.6 MPa (16 kg/cm²)
Hydraulic test pressure (seat)1.0 MPa (10 kg/cm²)
Standard thread connectionParallel fastening threads (IS 2643)
Practical Notes
Always verify the thread specifications (usually BSP parallel) to ensure compatibility with standard connecting plumbing fittings.
For hard water areas, inspect the washer and spindle mechanism periodically as scale buildup can cause premature failure.
Chromium plating quality (as per IS 4827) is crucial for preventing tarnishing and corrosion in wet environments.
