ACCESSIBLE (READILY) - correct answer ✔✔ Having a direct access without the necessity of
removing a panel, door, or similar obstruction.
AIR ADMITTANCE VALVE - correct answer ✔✔ One-way valve designed to allow air to enter the
plumbing drainage system when negative pressures develop in the piping system. The device
shall close by gravity and seal the vent terminal at zero differential pressure and under positive
internal pressures. The purpose of this device is to provide a method of allowing air to enter the
plumbing drainage system without the use of a vent extended to open air and to prevent sewer
gases from escaping into a building. Allowed by IPC/IRC, not allowed by UPC.
AIR GAP (DRAINAGE) - correct answer ✔✔ The unobstructed vertical distance through the free
atmosphere between the lowest opening from a pipe, plumbing fixture, appliance, or
appurtenance conveying waste to the flood- level rim of the receptor. Typically required to be
one inch, or twice the diameter of the waste pipe.
AIR GAP (WATER DISTRIBUTION) - correct answer ✔✔ The unobstructed vertical distance
through the free atmosphere between the lowest opening from a pipe or faucet conveying
