  • "Accessible" means having access to a fixture, connection, appliance, or equipment, possibly requiring removal of an access panel, door, or similar obstruction.

Accessibility

  • "Readily Accessible" means direct access without removing any panel, door, or similar obstruction.

Airbreak and Air Gap

  • An "Airbreak" is a physical separation between a fixture, appliance, or device and an indirect waste receptor.
  • An "Air Gap, Drainage" is the unobstructed vertical distance between the lowest opening from a pipe, plumbing fixture, appliance, or appurtenance conveying waste to the flood-level rim of the receptor.
  • An "Air Gap, Water Distribution" is the unobstructed vertical distance between the lowest opening from a pipe or faucet conveying potable water to the flood-level rim of a tank, vat, or fixture.

Backflow and Prevention

  • "Backflow" is the flow of water or other liquids, mixtures, or substances into the distributing pipes of a potable supply of water from any source other than its intended source.
  • A "Backflow Connection" is a condition or arrangement where reverse flow can occur.
  • "Backpressure Backflow" occurs due to an increased reverse pressure above the supply pressure, possibly caused by pumps, boilers, gravity, or other sources of pressure.
  • A "Backflow Preventer" is a device or means to prevent the flow of liquid from returning to the source of supply, also called a "Vacuum Breaker".

Valves and Fittings

  • A "Ball Cock" is a valve opened and closed by the fall and rise of an attached ball floating on the surface of the liquid.
  • A "Ball Joint" is a type of pipe connection in which a ball-shaped end is held in a cup-like shell, allowing movement in every direction.

Pipes and Joints

  • A "Bell or Hub" is a portion of a pipe that is enlarged to receive the end of another pipe of the same diameter for making a caulked or push-on joint.
  • A "Bending Pin" or "Iron" is a tool for straightening or bending lead pipe.
  • A "Blank Flange" is a pipe flange that is not drilled for bolt holes.
  • A "Blind Flange" is a flange that closes the end of a pipe, with no opening for the passage of liquid or gas.
