The vent pipe should have an internal diameter of at least 110 mm (4¼") and reach more than 300 mm (12") above the highest point of the toilet superstructure. Typically, the pit is at least 3 metres (10') deep and 1 to 1.5 metres (3' to 5') in diameter, depending on the number of users. Deep pits can last up to 20 or more years. [30]
A Fixture Unit is not a flow rate unit but a design factor. A fixture unit is equal to 1 cubic foot (0.028 m 3) of water drained in a 1 + 1 ⁄ 4 inches (32 mm) diameter pipe over one minute. [2] One cubic foot of water is roughly 7.48 US gallons (28.3 L; 6.23 imp gal). A Fixture Unit is used in plumbing design for both water supply and waste ...
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
This system is suitable for locations plumbed with 12.7 or 9.5 mm (1 ⁄ 2 or 3 ⁄ 8 inch) water pipes which cannot supply water quickly enough to flush the toilet; the tank is needed to supply a large volume of water in a short time. The tank typically collects between 6 and 17 L (1.6 and 4.5 US gallons) of water over a period of time.

Fittings allow multiple pipes to be connected to cover longer distances, increase or decrease the size of the pipe or tube, or extend a network by branching, and make possible more complex systems than could be achieved with only individual pipes. Valves are specialized fittings that permit regulating the flow of fluid within a plumbing system.
