International Plumbing Code®:

Providing Options for
Designers of Modern Public Restrooms

From its inception in 2000, the IPC has prioritized privacy for occupants of public restrooms. Updates and additions have been made to subsequent editions of the code to improve upon privacy concerns and to address concerns about maintaining appropriate behavior inside of public restrooms. This article highlights the changes that have been made to the various editions of the codes, up to and including the 2021 IPC and International Building Code (IBC®), which have come to offer a toolbox of practical and safe solutions for the design of the modern public restrom.

Private Sewage Disposal:

Flushing Out the Facts

Private sewage disposal systems are underground wastewater treatment structures, commonly used in rural areas without centralized sewer systems. They use a combination of nature and proven technologies to treat wastewater from household plumbing produced by bathrooms, kitchen drains and laundry. Like the heating, ventiliation, and air conditioning systems, and other equipment in your home, these systems must be properly used and maintained to prevent harm to your home, family and the environment. This article dives into the proper use and maintenance of  private sewage disposal systems.

Code Changes on A2L refrigerants

Based on changes approved
During the 2021 Group A code cycle

The U.S. EPA issued a rule in 2021 mandating the phasedown of HFC refrigerant production and use over the next 15 years. The EPA adopted a final rule accepting six refrigerant alternatives for use in residential and light commercial air conditioning equipment – all are classified as A2L refrigerants. This article provides a brief history of the transition to A2L refrigerants and provides an overview of the related code changes in the 2024 IMC, IBC, and IFC that will permit the use of A2L refrigerants for human comfort.

Rainwater harvesting systems:

Protecting our water resources
for the long run

Rainwater harvesting systems have been used throughout the world to provide precious water resources to areas where water is scarce. The CSA B805-18/ICC 805-2018 — Rainwater Harvesting Systems standard applies to the design, materials, installation and operation of rainwater harvesting systems for potable and non-potable applications. This article provides an overview of the standard and how it can be used as an alternative compliance path to Chapter 13 of the International Plumbing Code.

Cross-Connection Control

A Critical Line of Defense Against
Potable Water Contamination

We take cross-connection control for granted, but it is critical for safe, clean drinking water. Most of us can go to a faucet, water bottle filler, or drinking fountain and get a drink of potable water. This is due largely to the fact that cross-connection control is an inherit plumbing design and installation component. Cross-connection control consists of various methods, assemblies, and devices, that when installed and maintained properly, safeguard our potable water. When these controls fail, however, the results can be catastrophic.

Podcast

HPAC Engineering reached out to Jim Cika, director of PMG technical resources for the International Code Council (ICC) to talk about refrigerants. Major code changes on A2L refrigerants are fast-approaching. Will you be ready?

Studor Air Admittance Valves Revolutionizing the Plumbing Industry

Studor air admittance valve’s (AAVs) are used as a method for venting traps for fixtures and waste receptors. AAVs reduce the amount of vent piping required to terminate outdoors. An AAV is designed to open to admit air into the venting and drainage system when negative pressures (less than atmospheric pressure) occur in the vent system. An AAV closes by gravity to seal the vent terminal when the vent system pressure is equal to atmospheric pressure. At vent system pressures greater than atmospheric pressure, an AAV remains closed and seals tighter under greater pressure by the nature of the design. The closed AAV prevents any vapor in the vent system from entering the building. 

AAVs are required to conform to one of three ASSE standards. Stack-type air AAVs shall conform to ASSE 1050. Individual and branch-type AAVs shall conform to ASSE 1051. AAVs shall not be installed in non-neutralized special waste systems as described in Chapter 8 of the International Plumbing Code (IPC) except where such valves are in compliance with ASSE 1049, are constructed of materials approved in accordance with Section 702.5 of the IPC and are tested for chemical resistance in accordance with ASTM F 1412. Air admittance valves shall not be located in spaces utilized as supply or return air plenums. Air admittance valves without an engineered design shall not be utilized to vent sumps or tanks of any type.

The Studor Mini-Vent®, Maxivent®, Redi Vent®, Tec-Vent® must be installed in accordance with the manufacture’s installation instructions and the conditions noted in the ICC-ES PMG Product Certificate PMG-1025.

Pandemic Task Force

Board Task Force on Pandemics

Preparing Our Buildings & Communities for Disease-Related Threats

Many jurisdictions have already developed guidelines and policies in response to the COVID-19 pandemic. The International Code Council has been tracking these efforts and provides a compilation of resources for the building industry at www.iccsafe.org/coronavirus-response-center.

Due to the complex and non-uniform approaches implemented globally, it is imperative that all aspects of the built environment be thoroughly analyzed to develop a comprehensive response. Recognizing this critical threat to both new and existing construction, the Code Council and the National Environmental Health Association (NEHA) have established a new task force on pandemics to help our communities respond to COVID-19 and prepare for the next health threat.

Scope

The design and layout of buildings can have a significant impact on the health and safety of the occupants. This diverse task force will research the effects of the COVID-19 pandemic on the built environment. The group will then develop a roadmap and propose needed resources – including guidelines, recommended practices, publications, and updates to the International Codes (I-Codes) – that are necessary to overcome the numerous challenges faced during pandemics to construct safe, sustainable and affordable structures. The Code Council anticipates that the task force will complete:

  • A comprehensive review of current code requirements as they relate to prevention of the transmission of diseases and other serious health concerns. Any suggested revisions to current code requirements based on this assessment will be processed as proposed code changes to the I-Codes.
  • A comprehensive review of existing guides, executive orders, white papers, reports and standards, as they relate to design standards, preparedness, health considerations and tools for operating during a pandemic.
  • Identification of best practices and guides to address the design and layout of new and existing buildings.
  • A comprehensive package of public information materials.

The new task force will include a broad cross section of experts from the building safety, construction, design, health and insurance industries.

The Code Council Board of Directors, in consultation with NEHA, will appoint the members of this task force.
