Plumbing 101: Codes and Standards

tubing-1555009_960_720

Over the last 25 years, the environmental and social awareness of water scarcity has led to substantial reductions in water consumption in various plumbing fixtures.  This has created a new era of High-Efficiency Toilets (HETs) and High-Efficient Urinals (HEUs), presenting a whole new set of challenges to drain line functionality and plumbing systems in general.

In commercial buildings, the lack of substantial supplemental water flow has required a paradigm shift in the design of plumbing systems, either in terms of water supply (inlets) or sanitary drainage (outlets).

To grasp the total impact of these reductions in the drain lines, you first need to understand the importance of plumbing codes and standards and their relationship with both plumbing fixtures and plumbing systems.

American national standards institute (ANSI)

In the United States, there are two ANSI standards; one for vitreous and non-vitreous china plumbing fixtures and the other one for vitreous china non-water urinals.

The ASME A112.19.2 applies to all plumbing fixtures that discharge into gravity drainage systems. For example: water closets, lavatories, urinals, bidets, bathtubs, shower receptors, kitchen and bar sinks, service sinks, drinking fountains, and institutional application fixtures.

The ANSI/ASME A112.19.19 standard ensures the safety and sanitary condition to all waterfree urinals, such as Falcon’s waterfree and hybrid technologies.

International Plumbing Code (IPC)

The IPC is a member of the International Code Council’s codes, focusing primarily on promoting advanced, cost-effective plumbing technology and practices. “The purpose of [the International Plumbing Code] is to provide minimum standards to safeguard life or limb, health, property and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance, or use of plumbing equipment and systems.” (International Plumbing Code, Section 101.3)

UNIFORM PLUMBING CODE (UPC)

The UPC code establishes the minimum requirements and standards for the protection of the public health, safety and welfare, specifically related to the erection, installation, alteration, repair, relocation, replacement, addition to, use, or maintenance of plumbing systems within this jurisdiction (101.2 Scope).
The UPC includes “all potable water, building supply, and distribution pipes; all plumbing fixtures and traps; all drainage and vent pipes; and all building drains, and building sewers, including their respective joints and connections, devices, receptors, and appurtenances within the property lines of the premises and shall include potable water piping, potable water treating or using equipment, medical gas and medical vacuum systems, liquid and fuel gas piping, and water heaters and vents for same.”

 

Taken in sum, all sections of the Plumbing Code, give a great overview of authorized types of equipment, systems and specific requirements for the design and installation of proper sanitary drainage (including the requirement that all horizontal drain lines with a diameter of 3 inches or less have a minimum of 1/4 inch per foot or 2 percent downhill slope*, which is necessary for the functionality of waterfree urinal products.
