In modern plumbing, a drain-waste-vent (or dwv) is part of a system that removes sewage and greywater from a building, and regulates air pressure in the waste-system pipes to aid free flow waste is produced at fixtures such as toilets, sinks, and showers, and exits the fixtures through a trap, a dipped section of pipe that.
In the may 2011 issue of this magazine, i wrote a column titled, “is pvc an acceptable vent material for flue gases” in which i pointed out many problems and challenges associated with venting flue gases with polyvinyl chloride (pvc) pipe in the march 2012 issue, a representative of the air-conditioning. + 4ft (pvc 90 sanitary elbow) + 15ft (straight pvc) + 0ft (coupling terminal) = 315ft since table 75 shows a maximum allowable vent length of 135ft, the planned vent system length is acceptable the flex venting used on some of the vertical twin pipe and split vent options also reduces the maximum allowable vent. High efficiency equipment will cost significantly more than less efficient models, so there seems to be a movement by some manufacturers to promote the cheaper and less appropriate pvc materials even though they are combustible and not listed for combustion flue gas venting applications the other. Use appropriate temperature-type solvent cement for applica- tions below 32°f ( 0oc) • appropriate solvent and cleaner must be used for the type of vent pipe used (pvc or cpvc) installation examples for pvc/cpvc twin pipe venting note the correct position of combustion air inlet and gas flue out- let, as these are not.
