low-flow toilet
fixture consisting of a ceramic bowl w/ a detachable, hinged seat and lid and a device for flushing w/ water
water closet/toilet
valve that supplies a fixed quantity of water to fixtures for flushing purposes when actuated by direct water pressure
flushometer valve
a compartment in a water system containing air that elastically compresses and expands to equalize the pressure and flow of water in the system
air chamber
an outlet, pipe or receptacle for excess liquid
overflow
a flow of a liquid opposite to the usual or desired direction
back flow
a backflow of used or contaminated water from a plumbing fixture into a pipe supplying potable water due to negative pressure in the pipe
back-siphonage
a valve preventing flowing liquid such as sewage from reversing its direction
backwater valve/backflow valve
a cylindrical trap close on the bottom and having a cover plate for access, usually installed on the drain line from a bathtub
drum trap
a toilet bowl in which the flushing water enters through the rim and siphonic action initiated by a water jet draws the contents of the bowl through the trapway
siphon-jet
a toilet bowl similar to the siphon jet but having a smaller water surface and trapway
reverse trap
similar to siphon jet but having the flushing water directed through the rim to create a vortex that scourts the bowl
siphon-vortex
toilet bowl having a simple washout action and emptying through a small, irregular passage
wash down
any device controlling or stopping the flow of liquid or gas by a movable part that opens partially obstructs or shuts a passage etx
valve
a valve with a globular body closed by a disk seating on an opening in an internal wall
globe valve
a shutoff valve closed by lowering a wedge shaped gate across the passage
gate valve
a globe valve having an outlet at a right angle to the inlet
angle valve
a washerless valve opened by aligning holes in a disk, cylinder or ball
alignment valve
valve permitting a liquid or gas to flow in one direction only
check valve
the extension of a soil or waste stack above the highest horizontal drain connected to the stack
stack vent
a vent the provides circulation of air between a drainage and a venting system by connecting a vent stack to a horizontal drain between the first fixture and the soil or waster stack
relief vent
a circuit vent that loops back and connects with a stack vent instead of a vent stack
loop vent
single vent serving two fixtures drains connected at the same level
common vent
a vertical vent installed primarily to provide circulation of air to or from any part of a drainage system
vent stack
a vent connecting a fixture drain to a main or branch vent
individual vent
vent serving two or more traps and extending from in front of the last fixture connection of a horizontal branch to the vent stack
circuit vent
vent installed on the sewer side of a trap

vertical vent formed by a continuation of the drain line to which it connects
continuous vent
a vertical soil pipe
soil stack
vertical waste pipe
waste stack
a device (a type of trap) designed to intercept most greases and solids before they enter a wastewater disposal system.
grease trap
is that unit of plumbing system that conveys rain or storm water to a suitable pipe.
storm drain
also known as water conductor or downspout
roof leader
