MODULE 4 MAIN VENT (VENT STACK)- artery of venting system VENT STACK- Vertical vent pipe for proving a circulation of air STACK VENT- Extension of soil or waste stack above the highest horizontal draib connected to stack (SVTR) 2 PRINCIPAL CLASSIFICATION OF VENTS BRANCH VENT- horizontal vent pipe. Branch pipe to vent or stack 1. MAIN SOIL AND WASTE VENT GROUP VENT- branch bent (SOIL STACK)- Ventilate the soil and waste pipes portion of the soil-pipe INDIVIDUAL VENT- back vent; single trap stack where air is admitted means of UNIT VENT- Ventilates 2 fixture traps ore eliminating odors more fixture traps that discharge into a 2. MAIN VENT (VENT STACK)- “relief” sanitary cross with defectors “yoke” vents; to maintain CIRCUIT OR LOOP VENTILATION- atmospheric pressure in the waste VENTILATED 2 OR MORE pipe system portion of the vent pipe which serves as a terminal for the smaller. Relieve any back-pressure terminates in soil-pipe stack.  NATIONAL UNIVERSITY COLLEGE OF ARCHITECTURE Cluster Chair: AR. KAOLYNE GRACE C. HILARIO Cluster Heads AR. EMMARIE ROSE V. CRUZ AR. ANNIE C.

Adhesives: for plastic pipe and fittings  Joints and Connections Rubber Ring Method: inserting rubber gaskets into sleeves; for straight pipe connections Expansion Joints: rubber sealant between pipes to allow for relative movement due to temperature changes.  Joints and Connections Hubless Joints: Hubless pipe ends are wrapped around with neoprene rubber and clamped with steel plates Cement Mortar Joint: for sewer line Prohibited for new connections  Joints and Connections Welding/Soldering: for cast iron pipes and other steel pipe without threads. Method used when connecting pipes and fittings of different materials.  Joints and Connections Fusion Welding: a process that uses heat to join or fuse two or more materials by heating them to melting point. The process may or may not require the use a filler material. Butt Fusion  Joints and Connections Flared Joints: connecting copper and plastic tubes by flaring one end so as to receive a special fitting. Wiped Joint: a soldering joint wiped with cloth so as to shape the joint as required. Joints and Connections Slip Joint: one pipe slips within another, a seal being affected by caulking, gaskets or packing. Common for fixture traps and drains. Flanged Joint: used for connecting fixtures with drainage pipes. Fixtures are connected to floor with screws and bolts and connected to pipes by caulking, soldering, adhesive or threading. REFERENCES NATIONAL PLUMBING CODE OF THE PHILIPPINES NATIONAL BUILDING CODE OF THE PHILIPPINES ILLUSTRATIONS (FROM GOOGLE)  NATIONAL UNIVERSITY COLLEGE OF ARCHITECTURE Cluster Chair: AR.
