INSTALLATION OF SOIL, WASTE, VEN AND RAIN PIPES.

WATER

Soil, waste and vent pipes in shafts, under the floors etc shall consist of u.P.V.C. pipes as described earlier. Waste pipes from bottle trap to floor/urinal traps for wash basin, urinal and sink shall be of heavy class u.P.V.C. pipes and fittings. All horizontal pipes running below the slab and along the ceiling shall be fixed on structural adjustable clamps, sturdy hangers of the design as called for in the drawings. The pipes shall be laid in uniform slope and proper levels. All vertical pipes shall be truly vertical fixed by means of stout clamps in two sections, bolted together, built into the walls, wedged and neatly jointed. The branch pipes shall be connected to the stack at the same angle as that of fittings. All connections between soil waste and ventilating pipes and breach pipes shall be made by using pipe fitting with inspection doors for cleaning. Pipes shall be fixed in a manner as to provide easy accessibility for repair and maintenance and shall not cause obstruction in shafts. Where the horizontal run



61of the pipe is long or where the pipes cross over building expansion joints etc.,

suitable allowance shall be provided for any movements in the pipes by means of expansion joints etc., such that any such movement does not damage the installation in any way.

All u.P.V.C. pipes and fitting shall be jointed as per the manufacturers specification.

The jointed portion of the pipe shall be carefully leveled and aligned and the joint shall not be covered till the pipe line has been tested under pressure.

5.

Cutting and Making good:

Pipes shall be fixed and tested as building proceeds. The Contractor shall provide all necessary holes, cutouts and chases in structural members as building work proceeds. Wherever holes are cut or left originally they shall be made good with cement concrete 1:2:4: (1 cement: 2 coarse sand:4 stone aggregate 20mm nominal size) or cement mortar 1:2 coarse sand). Cured and the surface restored to original condition

Painting

All M S Hangers shall be painted as per the shade and colour approved by the Project Manager:



627. Testing

7.1.

Before use at site, all u.P.V.C soil pipes soil pipes shall be tested by filling up with water for at least 10 minutes. After filling, pipes shall be inspected for below holes and cracks. All defective pipes shall be rejected and removed from the site within 48 hours.

Pipes shall be tested after installation by filling up the stack with water. All opening and connections shall be suitably plugged. The total head in the stack shall however not 3m exceed.

Alternatively, the Contractor may test all soil and waste stacks by a smoke testing machine. Smoke shall be pumped into the stack after plugging all inlets end connections. The top end shall however be left open. The stack shall then be observed for leakages and all defective pipes and fittings removed or repaired as directed by the Project Manager.

A test register shall be maintained and all entries shall be signed and dated by the Contractor and the Project Manager or his representative.

The fixing shall be done by means of standard pattern holder bat clamps keeping he pipes about 1.5cm clears of the wall where to be laid on surface. Where it is specified to conceal the pipes, chasing may be adopted or pipes fixed in the shafts, ducts etc provided there is a sufficient space to work on the pipes with the usual tools. As far as possible, pipes may be buried for short distance provided adequate protection is given against damage and where so required special care to be taken at joints. Where directed by the Construction Manager /Architect, Pipe sleeves shall be fixed at a place the pipe is passing through a wall or floor for reception of the pipe and allow freedom for expansion and contraction and other movements. In case of pipe is embedded in walls or floors it should be of approved quality. Under the floors the pipes shall be laid in layer of sand filling.

CPVC pipes shall be jointed with male and female joints, using Solvent Adhesive, shall be taken to remove any burr from the
