- 2. Polyvinyl Chloride
- 8. the flowing back of used, contaminated, or polluted water from a plumbing fixture or vessel into a water supply pipe due to a pressure less than atmospheric in such pipe.
- 10. a device for lifting sewage by entraining it on a high-velocity jet stream, air, or water.
- 13. A water supply line that extends vertically one full story or more to convey water to branches or fixtures.
- 14. A fitting or device so designed and constructed as to provide, where properly vented, a liquid seal that will prevent the back passage of air without materially affecting the flow of sewage or wastewater through it.
- 15. An approved tank or pit that receives sewage or liquid waste and which is located below the normal grade of the gravity system and which must be emptied by mechanical means.
- 17. Indicates a recommendation or that which is advised but not required.
- 18. A drain installed to receive water collecting on the surface of a roof and to discharge it into a leader, down spout, or conductor.
- 19. A vent that also serves as a drain
- 20. The time period that the penetration firestop system, including the penetrating item, limits the maximum temperature rise of 325F above it initital temperature through the penetration of the nonfire side, where tested in accordance with ASTM E814 or UL 1479
- 24. A joint obtained by joining of metal parts with alloys that melt at temperatures exceeding 840F, but less than the melting temperature of the parts to be joined.
- 26. A piece of equipment that disinfects instruments and equipment by way of heat.
- 27. An exterior vertical drainage pipe for conveying storm water from roof or gutter drains.
- 28. a combination of elbows or bends in a line of piping that brings one section of pipe out of a line but into a line parallel with the other section.
- 29. A joint obtained by the joining of metal parts with metallic or alloys that melt at temperatures up to and including 840F
Down
- 1. A barrier free floor with a shower and drainage fixture.
- 3. An impairment of the quality of the potable water that creates an actual hazard to the public health through poisoning or the spread of disease by sewage, industrial fluids, or waste.
- 4. A device and system of piping that maintains a water seal in a remote trap.
- 5. the slope or fall of a line of pipe in reference to a horizontal plane. In drainage, it is usually expressed as the fall in fraction of an inch or percentage slope per foot length of pipe.
- 6. A group of two or more similar, adjacent fixtures that discharge into a common horizontal waste
- 7. a section of potable water pipe which contains water that has no flow or does not circulate.
- 8. A part of the piping system other than the main, riser, or stack.
- 9. indicates a mandatory requirement
- 11. the installation of all parts of the plumbing system that can be completed prior to the installation of fixtures. This includes drainage, water supply, vent piping, and necessary fixture supports.
- 12. A drain that collects subsurface or seepage water and conveys it to a place of disposal.
- 16. the liquid phase produced by condensation of a gas or vapor.
- 21. The pipe or tubing that connects the outlet of a plumbing fixture to a trap.
- 22. A pipe connecting upward from soil or waste stack to a vent stack to prevent pressure changes in the stacks.
- 23. Acrylonitrile-butadiene-styrene
- 25. The lowest point in the cross-section of the horizontal waterway at the exit of the trap.
