6 Proper Ventilation Plumbing System

Proper VENTILATION PLUMBING SYSTEM ** PROPER VENTILATION IS AN IMPORTANT PART OF A PLUMBING SYSTEM. EVERY PLUMBING FIXTURE. FROM A TOLET TO A SHOWER NEEDS TO BE CONNECTED TO VENTILATION PIPING. THE PRESSURE OF QUTSDE AIR DRAWN IN FROM VENTLATION PPES HELPS PUSH WASTE DR USED WATER DOWN THROUGH ORAIN PIPES. VENT PPES ALSO LEAD THROUGH A ROOF TO EXPEL HARMFUL GASES OR UNPLEASANT ODORS FROM A HOME. TRY THESE STEPS TO VENT PLUMBING STEP CHOOSE A PIPE MATERIAL FOR YOUR VENTI- 1 LATION SYSTEM. CONSIDER WHICH PIPE MATERIAL BEST FITS YOUR NEEDS, BUDGET, AND ANY EXISTING PIPING. * Familiarize yourself with local plumbing and building codes. The kind of pipes you can use and how they will be structured depends on your local code requirements. * Pipe options include brass, copper, galvanized steel, cast iron, lead or PVC. Depending on the gases emitted by waste running through your system, some pipe materials can corrode more easily than others. * The vent stack should be equal in size to the waste trunk or line you are venting, for instance, a 3 inch sanitary line requires a 3 inch vent. * Plastic or PVC pipe cannot be used in to go through an attic space that provides return air for an HVAC system due to fire codes in many juridictions. * Remember that you will need to support the weight of your vent stackout, so lighter pipes may be preferred. PLAN THE LOCATION AND LAYOUT OF YOUR STEP PIPING. 2 CONSIDER ASKING A PROFESSIONAL PLUMBER TO HELP YOU WITH THIS. VISIT A HARDWARE STORE TO GET PIPE, STEP FITTINGS, AND MATERIALS FOR JOINING AND 3 SUPPORTING YOUR VENT STACK. MEASURE AND CUT THE PIPE YOU NEED ARDWAR PLUMBING SUPPLIES The amount of vent piping required may be based on how many cubic feet of air you need to move through the pipes as well as local regulations. Buy pipe fittings to connect pieces of pipe together. Fittings come in different shapes and sizes depending on the types of pipe being connected and whether turns or bends are needed. STEP CONNECT A STACK VENT TO A SOIL STACK. 4 THE SOL STACK PIPE CONNECTS TO A HOUSES MAIN DRAIN AND EXTENDS UPWARDS TOWARDS THE ROOF. SECONDARY PIPES CARRYING WASTE OR USED WATER FROM PLUMBING FIXTURES RUN INTO THE SOIL STACK TO BE EMPTED. A stack vent will lengthen the vertical soil stack pipe to help it eventually go through a roof. It should extend above the highest horizontal pipe connected to the soil stack. RUN MORE VENT PIPING AS DIRECTED BY THE STEP CONFIGURATION OF DRAIN PIPES OR OTHER REQUIREMENTS. VERTICAL VENTS SHOULD BE AS STRAIGHT AS POSSIBLE TO PREVENT CONDENSATION FROM BUILDING IN THE PIPES. HORIZONTAL VENTS SHOULD SLANT DOWN TOWARD FIXTURES SO GRAVITY CAN ASSIST IN MOVING WASTE AND WATER. * A type of pipe called a common vent may be used to vent 2 fixture drains where they meet and connect. * Individual vents are pipes that connect with the ventilation system above plumbing fixtures. The individual vents equalize pressure on a fixture trap, a cur ved piece of pipe that must hold water and prevents gases from building up inside a house. * Vertical ventilation pipes called vent stacks provide air circulation to any part of the plumbing system. Vent stacks can run parallel with waste pipes to ensure proper ventilation in tall buildings. Sub-vents may be branched together to exit 1 vent stack, allowing for only 1 hole in the roof for ventilation. *** MARK AND DRILL A HOLE IN THE ROOF TO FIT STEP THE WIDTH OF YOUR VENT STACK PIPE. YOU MAY BE ABLE TO HAMMER A NAL THROUGH THE ROOF AS A GENERAL REFERENCE FOR YOUR DRILLED HOLE A HOLE SAW MAY BE USED FOR MAKING THE HOLE FOR THE VENT STACK *** Source http://www.buyerschoiceinspections.com/plumbing-fundamentals http://en.wikipedia.org/wiki/Drain-wasto-vent_system ALL PLUMBING, INC. unborik Trap_(plumbing) g-basics.com/drainage/vent-piping.htm I PARTS & SERVICE
