63. Wet vent – that portion of a vent pipe through where waste water also flows through. 64. Looped vent - a vertical vent connection on a horizontal soil or waste pipe branch at a point downstream of the last fixture connection and turning to a horizontal line above the highest overflow level of the highest fixture connected there at the terminus connected to the stack vent 65. Local vent – a pipe or shaft to convey foul air from a plumbing fixture or a room to the outer air. 66.The main vent is that potion of the vent pipe system, serving as terminal for smaller forms of individual and grouped fixture trap ventilation. The drainage system is a combination of 67. Waste pipe, 68. Vent pipe, and 69. Water supply. In a plumbing system it is the portion of the drainage pipe installation designed to maintain a balance atmospheric pressure inside the system to prevent problems such as: 70. Trap seal loss 71. Retardation of flow 72. Deterioration of Materials

Trap seal loss can be attributed to the following factors: 73. Siphonage 74. Back pressure 75. Evaporation 76. Capillary Action Types of Ventilation 77. Natural vent 78. Mechanical vent 79. Cross-Ventilation - The circulation of fresh air through open windows, doors, or other openings on opposite sides of a room. Types of objectionable Traps 80. Full S Traps 81. ¾ S Trap 82. mechanically sealed trap 83. Light metal partition traps 84. Ventilation of a plumbing system, is that portion of the drainage pipe Installation, designed to maintain a balance atmospheric pressure 85. Trap seal loss can be attributed to inadequate ventilation of the trap and the subsequent minus and plus pressures inside the system. 86. -100 Show a detailed section of a P-Trap showing the diff. parts and trap seal height.
