The video starts by defining 'development length' as the length along the centerline of the pipe and fittings. It then clarifies that a vent also serving as a drain is called a 'wet vent'.
For an air test, air is forced into the pipe system until a uniform gauge pressure of 34.5 kPa, or equivalent to 254 mm of mercury, is reached. Access to each septic tank requires at least two manholes, each with a minimum dimension of 58 mm, or an equivalent removable cover slab.
A 'cesspool' is described as a non-watertight lined excavation in the ground that receives sanitary drainage, designed to retain solids while allowing liquid to seep through. An 'offset' in piping refers to a combination of elbows or bends that move a pipe out of line but parallel to its original path.
The 'Durham system' is a term for a soil or waste system using threaded pipe, tubing, or rigid construction with recess drainage fittings. Brass fittings typically contain 85% copper.
The 'dry stand pipe' is identified as an obsolete type of fireline installation. The interval distance between cleanouts along a lateral line is 15 meters.
A 'house sewer' is the part of the plumbing system extending from 4 to 5 feet from the building's foundation wall to the junction with another sewer. A 'scupper' is a box-like collection device located on the exterior of a building that receives stormwater on one side.
Cocked or screwed joints are applicable to cast iron pipes. A 'privy' is defined as an outhouse or structure used for the deposition of excrement.
The 'flood level' is when water overflows the top or rim of a fixture. A 'flush valve' is a device at the bottom of a tank to flush water closets, and a 'fixture supply' is a water supply pipe connecting the fixture to the fixture branch.
Devices discharging clear waste water into the building drainage system must do so through an indirect waste by means of an air gap. The statement that an owner has the right to construct a private sewage disposal system, even if a public sewer is available, is false.
The current chairman of the board for Master Plumber is Engineer Eligan.
