Sanitation, Plumbing Design and Installation (Part 2) | Master Plumber Licensure Exam Refresher

Shower Drain Area and Height00:06:14

The minimum area and dimensions, maintained from a point above the shower drain outlet to a height of 1.78 meters with no protrusions, are also discussed.

Rainwater Conductor and Blind Flange00:00:24

The video begins by defining the vertical portion of a rainwater conductor as a "downspout" and a flange that closes the end of a pipe as a "blind flange."

Building Drain and Building Subdrain Definitions00:00:56

It explains that the lowest horizontal piping receiving discharge from soil waste and other drainage pipes inside building walls is the "building drain." A portion of an underground system that cannot drain by gravity is a "building subdrain."

Pipe End Closure and Bathtub Height00:01:39

A fitting used to close the end of a pipe is defined as a "cap." The approximate height of a built-in bathtub from floor level to fixture rim is stated as 16 inches.

Catch Basin and pH Values00:02:15

A receptacle for retaining liquids to allow settleable material to deposit is identified as a "catch basin." The pH value of 0 is described as "acidic."

Relief Vent and Water Closet Height00:02:51

A "relief vent" is identified as having the primary function of providing air circulation between drainage and vent systems. The approximate height of a water closet from floor level to fixture rim is 15 inches.

Liquid Waste and Vent System00:03:27

The discharge from any fixture or appliance that does not receive fecal matter is categorized as "liquid waste." A "vent system" is described as pipes installed for air circulation within the plumbing system to protect trap seals from siphoning and back pressure.

Lavatory Height and pH 1400:04:11

The approximate height of a lavatory from floor level to fixture rim is stated as 31 inches. A pH value of 14 is defined as "alkaline."

Laundry Tray Height and Dry Standpipe Sizes00:04:44

The approximate height of a laundry tray from floor level to fixture rim is 34 inches. The minimum pipe size for a dry standpipe is 102 mm.

Condensate Drain and Standpipe Connections00:05:18

The minimum pipe size for a condensate drain for a 3-ton AC unit is 20 mm. The minimum diameter for a dry standpipe requiring a three-way Siamese connection is 125 mm, and for a four-way Siamese connection, it is 152 mm.
