Highlights
The video begins by defining a fixture supply as a water supply pipe connecting a fixture to a fixture branch. It then describes a flush valve as a device at the bottom of a tank used for flushing water closets and similar fixtures.
The flood level is introduced as the point where water overflows the rim of a fixture. The discussion then moves to copper tubing support, stating that it should be supported at approximately 1.8-meter intervals for piping 38 mm in diameter and smaller.
A privy is defined as a structure for the deposition of excrement. The video explains that a building sewer should be tested by completely filling it with water from the lowest to the highest opening. Caulked or screwed joints are specifically applicable to cast iron.
A scupper is described as a box-like collection device on the exterior of a building that receives stormwater. A house sewer is defined as the part of a plumbing system extending 4 to 5 feet from the inner face of the foundation wall to the junction with another sewer.
Restaurant and other special use sinks may be made of approved type bonderized and galvanized steel sheet of not less than 16 gauge. Horizontal drainage lines connecting to other horizontal drainage lines should enter through combination Y and 1/8 bend branches or other approved fittings of longer sweeps, specifically 45-degree Y branches.
A public sewer is considered unavailable if it or any exterior drainage facility connected to it is located more than 61 meters from any proposed building. Rainwater drains from roofs, inner courts, and similar areas should discharge outside of the building and not be connected to soil and waste pipe systems.
Cleanouts may be omitted on short horizontal drainage pipes installed at a slope of 72 degrees or less from the vertical line. A fullway gate valve should be installed on the cold water supply pipe to each water heater near the water heater.
When testing the entire system, all openings in the piping should be tightly closed except the highest opening. An air test is used to check the tightness of a drainage or plumbing system if it is believed to be defective. Indirect waste pipes measuring 4.1 meters in length should be directly trapped, but these traps do not need to be vented. Bell and spigot and hubless pipes should be supported at every story or closer, while plastic pipes should be supported at every 1-meter interval.
