Water Supply System Installation

A
Planning & Layout
  • Study plumbing drawings and identify connection points
  • Mark pipe routes on walls/floors following the drawings
  • Identify fixture locations and required pipe sizes
  • Plan for minimum bends to reduce pressure loss
  • Ensure adequate clearances from electrical lines (min. 300mm)
  • Plan valve locations for isolation of different areas
  • Create detailed material take-off list based on layout
  • Get layout approval from site engineer before proceeding
B
Pipe Cutting & Threading
  • Measure pipe lengths accurately, allowing for fittings
  • For GI pipes: Use pipe cutter or hacksaw with cutting guide
  • Remove burrs with reamer or file to ensure smooth flow
  • For threading GI pipes: Use appropriate die size
  • Apply cutting oil during threading for smooth threads
  • For PVC/CPVC: Cut square with fine-tooth saw or pipe cutter
  • Chamfer edges of plastic pipes for easier insertion into fittings
  • Clean pipes thoroughly after cutting
C
Pipe Joining Methods
Pipe Material Joining Method Procedure Key Points
GI Pipes Threaded Joints Apply Teflon tape or pipe joint compound, tighten with pipe wrench Wrap Teflon clockwise, use 3-4 wraps, avoid over-tightening
PVC/UPVC Solvent Cement Clean, apply primer, apply cement, insert and twist, hold for 30 seconds Use appropriate solvent for pipe type, ensure dry surfaces
CPVC Solvent Cement Clean, apply CPVC primer, apply CPVC cement, join, hold for 30 seconds Use only CPVC specific cement, avoid excess cement inside pipe
PPR Heat Fusion Heat pipe and fitting to 260°C, join when soft, hold until cooled Use PPR fusion tool, maintain correct heating time based on diameter
HDPE Butt Fusion/Electrofusion Clean ends, heat to melting point, join under pressure, cool Requires specialized equipment, follow temperature guidelines
D
Pipe Support & Spacing

Proper support prevents pipe sagging, vibration, and stress on joints. Below are maximum recommended intervals for horizontal pipe supports as per IS:2065.

Pipe Material Pipe Size (mm) Horizontal Spacing (m) Vertical Spacing (m)
GI 15-20 2.5 3.0
GI 25-40 3.0 3.6
GI 50-150 3.6 4.5
PVC/CPVC 15-25 0.75 1.0
PVC/CPVC 32-50 1.0 1.5
PVC/CPVC 65-80 1.5 2.0
E
Expansion Considerations

Thermal expansion must be accommodated, especially for plastic pipes and hot water lines.

  • For PVC/CPVC: Allow 10mm expansion space per 4m of pipe
  • Install expansion loops or offsets in long straight runs
  • Use expansion joints where necessary
  • For vertical risers, allow for movement at each floor
  • Use loose clamps that allow for axial movement

Essential Practice: Always install isolation valves at key points in the system, including main supply, branch lines, and before each fixture. This allows for repairs without shutting down the entire system.

5

Drainage System Installation

A
Drainage System Components
  • Soil pipes: Carry toilet waste (100mm diameter)
  • Waste pipes: Carry sink, basin, shower waste (75-80mm diameter)
  • Vent pipes: Prevent trap seal loss and allow proper flow
  • Traps: Water seals preventing sewer gas entry
  • Floor traps: Collect water from bathroom floors
  • Gully traps: Connect waste pipes to main drainage
  • Manholes: Access points for inspection and cleaning
  • Inspection chambers: Smaller access points
  • Grease traps: For kitchen waste lines
B
Pipe Gradients & Sizing

Proper gradient ensures adequate flow velocity for self-cleaning action while preventing excessive speeds that can break trap seals.

Pipe Type Recommended Gradient Min. Diameter Notes
Horizontal soil pipe 1:40 to 1:60 100mm Lower gradient for heavier flow
Horizontal waste pipe 1:40 to 1:50 75mm Gradient depends on length and fixtures
Branch waste pipe 1:30 to 1:40 32-40mm For single fixture connection
Main drain line 1:100 to 1:200 150mm Based on calculated flow rate
C
Laying Underground Drainage
  • Excavate trench to required depth and gradient
  • Provide 150mm sand bedding for pipe support
  • Lay pipes starting from lower end (outlet) to higher end
  • Join pipes according to material requirements
  • Ensure socket ends face upstream
  • Provide minimum 300mm cover above pipe crown
  • Test for leaks before backfilling
  • Fill with approved material in 150mm layers, compacting each layer
D
Trap Installation
  • Install P-traps for washbasins, sinks and showers
  • Use S-traps or P-traps for water closets based on outlet direction
  • Floor traps should have minimum 50mm water seal
  • Install bottle traps where space is limited
  • Ensure trap outlet connects properly to waste pipe
  • Position cleanout access for easy maintenance
  • Secure traps to prevent movement
E
Vent Pipe Installation

Vent pipes maintain atmospheric pressure in drainage systems, preventing siphonage of trap seals and allowing proper flow.

  • Install vent pipes to extend minimum 2m above roof level
  • Connect vent stacks to soil/waste stack below lowest fixture
  • Install air admittance valves where conventional venting is difficult
  • Maintain minimum 75mm diameter for vent stacks
  • Fix vent pipes securely to walls/structures
  • Terminate vent pipes with mesh to prevent bird entry
  • Ensure vent termination is away from windows/air intakes (minimum 3m)

Design Principle: A properly designed drainage system should be self-scouring (minimum velocity 0.75 m/s), self-venting, and accessible for maintenance.
