Summary
Highlights
Plumbing System Design and Pipe Manufacturing00:06:05
A 'home run' plumbing design features centrally located manifolds distributing water to each fixture with dedicated hot and cold lines. A 'welded pipe' is a steel pipe manufactured by drawing flat steel strips through a die to form a cylindrical shape.
Plumbing Fixture Definitions00:00:24
The video starts by defining a bidet as a plumbing fixture used for washing external genitalia. It then defines a riser as a vertical pipe or reservoir into which water is pumped to give it a head.
Piping Components and Seals00:01:01
A 'cut pipe' is described as a piece of pipe over 300mm in length but less than commercially available, functioning as an extension. A 'fixture trap' is defined as a fitting or device that provides a liquid seal to prevent sewer gas emission when properly vented.
Ventilation and Permits00:01:44
A 'yolk vent' is explained as an interconnection between a vent stack and a soil stack. The video then states that a plumbing permit becomes null and void if work is not commenced within one year.
Safety Valves and Water Flow00:02:20
A 'temperature pressure relief valve' is identified as a valve installed on a hot water tank to release temperature or pressure buildup. A 'circulating pump' is used to boost hot water pressure.
Materials and Wastewater Treatment00:03:07
CCI P means 'central cast iron pipe'. 'Anaerobic bacteria' are identified as bacteria that require no oxygen for sewage decomposition. A 'tailpiece' is the pipe or tubing connecting a fixture's outlet to the trap.
Fittings and Pipe Standards00:03:52
A 'bushing' is a fitting to connect the male end of a pipe to a larger-sized fitting. Polyvinyl Chloride (PVC) pipes for Drain Waste Vent (DWV) are manufactured based on standards set by 'ASTM'.
Pipe Classifications and Types00:04:45
RCPC means 'reinforced concrete pipe culvert'. 'Schedule 40' is generally considered standard weight pipe. The simplest and cheapest bonnet design of a valve is 'bolted'.
Rainwater and Lifting Equipment00:05:26
A 'rainwater leader' is a pipe that conveys rainwater from the roof to the storm drain. 'Rigging' is the securing of equipment or materials for lifting using ropes, chains, or webs.
