Quick answer
A new house in Chandigarh, Mohali or Panchkula usually needs CPVC pipes and fittings for hot and cold supply, UPVC for tank and outdoor lines, SWR pipes and fittings for drainage, brass and CPVC valves, concealed valve bodies, a water pump with NRV and foot valve, solvent cements, clamps and PTFE tape. Buy the hidden items before tiling and the visible fittings later.
Plumbing material is bought in two rounds on most house projects. The first round goes into the walls and floors before plastering and tiling. The second round is the visible fittings like taps, mixers and showers. Most delays and extra costs come from missing items in the first round, so this checklist focuses on getting that right.
Round 1: Before plaster and tiles
Water supply
- CPVC pipes in the sizes on your plumber’s drawing, commonly 1/2 inch, 3/4 inch and 1 inch
- CPVC elbows, tees, couplers, reducers, end caps and unions
- CPVC brass adaptors (male and female threaded) for every tap and valve point
- UPVC pipes and fittings for tank connections and outdoor taps
- CPVC and UPVC solvent cement, kept separate
Valves and concealed fittings
- Main inlet valve (gate or ball valve)
- Ball valves for each bathroom, kitchen and geyser line
- Concealed valve bodies and diverters for showers and mixers
- Pressure reducing valve if you expect high pressure
Drainage
- SWR pipes, usually 75 mm and 110 mm
- SWR bends, tees, Y-tees, door elbows and reducers
- Floor traps, nahani traps and gully traps
- Rainwater outlets and pipes for the roof
- Rubber rings and lubricant for ring-fit joints
Tanks and pumps
- Monoblock or self-priming pump sized to your building
- Foot valve and non-return valve
- Float valve or level controller for the overhead tank
- Booster pump if upper floors will have low pressure
Small items that cause delays when forgotten
- Pipe clamps and saddles
- PTFE tape and thread sealant
- Pipe cutter, deburring tool and spare cement
- Test plugs and end caps for pressure testing
Pressure test before you close the walls
Ask your plumber to pressure test the supply lines before plaster. Fill the system, cap the outlets and watch for any drop over a few hours. Finding a leak now costs a few minutes. Finding it after tiling costs a broken wall.
Round 2: Visible fittings
- Taps, bib cocks and pillar cocks
- Wall mixers, basin mixers and sink mixers
- Overhead and hand showers, health faucets
- Angle valves and connection pipes
- Wash basins, waste couplings and bottle traps
- Flush valves or cistern fittings
- Bathroom accessories in a matching finish
