FEBRUARY 2022 | Chairman’s Message
March 11 — World Plumbing Day — is fast approaching, and once again we will celebrate across the world the contributions of the plumbing industry toward the health and safety of our planet. Every year plumbing is getting more and more respected as an essential profession that contributes to the well-being of our economies. Here in the United States, we have neglected investment in infrastructure, causing many disruptions in our drinking water and sanitation. Many of us take this for granted every day until something breaks.
Fortunately, our president recognizes that we as a country are at a critical point when it comes to our infrastructure. One of the main topics of his infrastructure investment is the removal of lead piping in our water systems. Most plumbers know that the name plumber derives from the Latin word plumbum, which means “lead” on the periodic table. Lead was the material used for the early systems of the Roman Empire. Some historians suggest that the reason for the decline of the Roman Empire was too much lead in the drinking water. It’s funny how history continues to repeat itself, but with a $15 billion to $30 billion investment, we are on a path to removing all lead lines throughout the country and providing good-paying jobs for plumbers.
The WPC is still on hold regarding educational scholarships. We will discuss this at our upcoming virtual executive board meeting. The world is not quite ready yet to open all borders for travel. The WPC scholarships have been our greatest achievement and we want everyone to experience the sharing of educational knowledge in the safest manner possible. We are monitoring the situation and will make our announcements as soon as possible. Speaking of training, the organization for which I work, the United Association of Plumbers and Pipefitters, holds an annual training seminar in Ann Arbor, Michigan, that brings together more than 2,000 instructors from all over the United States and Canada to be trained in the best methods of teaching plumbing, HVAC, welding and CAD, just to mention a few. We also host an apprentice contest that brings the most talented apprentices from more than 50,000 apprentices from Canada, the USA and Australia. The UA has sponsored a winner form the WPC scholarship fund to attend this event as well. We look forward to hosting another winner from the WPC soon.
I was hoping that I wouldn’t have to mention the pandemic in this newsletter, but it seems like it won’t be going away anytime soon. The world is growing frustrated with mask mandates, and protests and disruptions are becoming the norm as we all struggle to get back to normal. Energy prices have continued to rise, and raw material shortages has caused long delays in construction and manufacturing. The most pressing issue facing the world today is a possible war in Ukraine. Our prayers go out to all world leaders to come to some agreement that will avert any more senseless wars.
In closing, I hope everyone in the plumbing community is safe and has a prosperous New Year. Don’t forget to send in your World Plumbing Day celebration stories and photos so we can post on our website.
IN THIS ISSUE:
An Optimized Sanitary Stack Configuration for Mid-Rise Multifamily Construction
Submitted by John Lansing, CPD, LEED Green Associate, is a Certified Plumbing Designer
Republished with permission from ASPE Pipeline
The design practices surrounding American sanitary drainage and vent systems closely reflect those in plumbing codes published in the first half of the 20th century. While venting methods such as circuit venting and horizontal wet venting were more recently introduced in some areas of the country, these configurations can be found in the National Bureau of Standards (NBS) publications, which are essentially the framework for the International Plumbing Code (IPC) and Uniform Plumbing Code (UPC®).
As building drainage theory progressed in the second half of the 20th century, mostly led by the Building Research Station (BRS) and Heriot-Watt University in the United Kingdom, drainage design in American plumbing codes remained mostly the same. This is prominently demonstrated by the emphasis on fixture vent piping over the venting of sanitary stacks, particularly for stacks serving fixtures in mid-rise buildings without auxiliary vent stacks. A majority of national standards utilize stack venting as a primary means of venting fixtures, a concept more familiar to those in the U.S. as the Philadelphia stack or the single-stack vent system, which can be found in Chapter 9 of the IPC and Appendix C of the UPC.
The following discussion will focus on the development and varying requirements of the single-stack vent system and proposals for modifications to the American variation to increase the functionality of this method in mid-rise multifamily construction.
After the end of World War II, the UK launched efforts to rebuild the hundreds of thousands of homes that were destroyed, seeking new strategies to optimize labor and resources. This led Alfred Wise of the BRS to investigate a simplified approach to sanitary drainage stacks. With extensive experimental testing, Wise developed a drainage configuration that allowed the elimination of individual fixture vents, also known as anti-siphon vents, relying instead on the free passage of air through the top of the drainage stack to limit negative pressure development to protect the water seals in fixture traps. Wise found that if the length of the horizontal drain between the fixture trap and stack connection was limited, the stack configuration was suitable for serving up to 10 floors of fixtures (see Figure 1).
Variations of Wise’s single-stack configuration quickly spread throughout Europe, Asia, Latin America, Africa and Oceana. Wise’s reports seem to indicate that he was unaware that a nearly identical configuration was already in use in Philadelphia. This American variation was initially developed by Boston architect J. Pickering Putnam and introduced at the 1911 American Institute of Architects (AIA) convention in San Francisco. Sometime after the development of the fixture unit method, a load sizing table was introduced for the Philadelphia stack configuration, along with stack height limits for each stack diameter. The Philadelphia stack was further developed by the American Society of Plumbing Engineers (ASPE) and eventually was featured in the appendix of the UPC in 2006 and Chapter 9 of the IPC in 2012 (see Figure 2).
Despite being used in Philadelphia for more than a century and being listed as an approved method in the IPC, the single-stack configuration has failed to gain widespread use in the U.S., likely due to some key design limitations.
Fundamental Design Requirements
Design requirements for the single stack vary in each country, along with the name of the configuration itself, with China and Japan describing the method as extension ventilation and Europe using the term primary ventilation. One common principle shared by almost all national variations is that the single stack allows the elimination of all vent piping anywhere along the stack or serving the fixtures connecting to the stack, with the one exception being the top of the stack itself, extending beyond the top fixture connection full size and terminating to the atmosphere. Most national and regional standards, with some exceptions, have a maximum allowable pressure differential of 1 inch (25 mm) of water column at fixture traps, allowing the performance between drainage systems to be more easily compared.
Fixtures on the Lowest Floor
The pressure surge problems associated with fixtures connecting directly above or downstream of a stack are almost universally recognized in plumbing codes and design guides. Most standards require fixtures on the lowest floor to connect downstream of the stack at a specified minimum distance and avoid connecting to the lowest floor above the stack base unless the lowest floor connection can be made above 2.5 to 8 feet (0.75 m to 2.5 m) or so above the stack base. Standards in Germany and China suggest providing a vent from the lowest floor fixtures and terminating this vent into the sanitary stack with a wye fitting at the same floor. In the UK, fixtures on the lowest floors connect into a stub stack, which is essentially a capped stack roughly 6 feet (2 m) in height. The stub stack connects horizontally downstream of the stack, relying on the airflow within the upper portion of the horizontal piping to alleviate pressure differentials.
The Philadelphia stack, however, requires separating out the two lowest floors for stacks greater than three floors in height. The stack serving the lower two floors may also use the Philadelphia configuration or may use another venting option, such as horizontal wet venting, both of which require extending a vent running from the lowest floor to an atmospheric termination point. Providing vent piping along the entire stack length undermines the advantages of the configuration over the typical horizontal wet vent stack (see Figure 3) and is unnecessary in this application for the protection of water seals.
As drainage stacks increase in height, the amount of airflow required to alleviate negative pressure from drainage increases. Depending on the design standard, the single stack is limited to a maximum of 10 to 20 floors to avoid airflows that would cause water seals in traps to fail. Once a stack height is considered too great, most design standards recommend providing an auxiliary vent stack connecting above the sanitary stack base, along with intermediate relief connections along the length of the stack. This configuration, widely known as the secondary ventilated stack, still allows fixtures to connect into the stack without a vent connection between the trap and stack connection.
For the 4-inch stack, a typical size for stacks serving bathrooms in most countries, the Philadelphia configuration is effectively limited to 75 feet (23 m)*, a height equivalent to about seven or eight floors. This height may be exceeded by increasing the stack diameter by one size. The 5-inch stack, typically considered a special-order size, is limited to 160 feet (49 m). The IPC also requires an auxiliary vent stack for the single-stack system if the height exceeds more than five floors, though this is a standard requirement for all sanitary stacks in the IPC and it may have been the intention to add the single stack to the list of exempted configurations.
Horizontal Distance from Stack Limitations
To avoid issues of self-siphonage, design standards limit horizontal drainage branch lengths between the trap and the branch connection to the stack. In Europe, this is generally limited to somewhere between 13 feet (4 m) and 33 feet (10 m). The UK has no limits for water closets or bathtubs but limits lavatories to a maximum of 10 feet (3 m). For the Philadelphia variation, water closets may be up to 8 feet (2.5 m) from the stack, while other fixtures may be up to 12 feet (3.7 m). Most configurations, including the Philadelphia stack, allow an S trap from the lavatory, though the Philadelphia stack requires increasing the fixture drain from a 1½-inch drain to a 2-inch drain prior to transitioning vertically to provide additional protection against self-siphonage.
Proposed Modifications to the Single Stack
Thanks to a research grant provided by ASPE’s Portland Chapter and assistance from Dr. Michael Gormley of Heriot-Watt University, a new variation of the single stack is being proposed in the upcoming 2024 UPC. This variation addresses the issues with the impractical venting requirements of the Philadelphia stack for fixtures on the lower floors by utilizing the approach used in Germany and China (see Figure 4). The proposal also only requires separating the first floor from the stack for stacks less than 75 feet (23 m). These minor modifications to the single-stack method will significantly increase the practicality of the configuration, making it a viable alternative to conventional sanitary stacks for mid-rise multifamily construction.
*4-inch stacks greater than 75 feet in height may only be used if the load does not exceed 24 drainage fixture units (DFU), equivalent to six floors of bathrooms.

IWSH Supports Access to Revolutionary Mobile App to Increase Women’s Access to Public Toilets in India
The International Water, Sanitation and Hygiene Foundation (IWSH) is pleased to announce its support for a cause led by Woloo, an Indian startup company whose app aims to ensure women access to clean, safe and hygienic toilets in public places.
The app, which is available on Android devices and is coming soon to IOS, helps women locate the nearest washroom when they are away from their home or office.
Even though women comprise more than 48 percent of the Indian population, lack of access to such facilities remains a problem. Finding a usable toilet in public spaces can be a challenge for women of all socioeconomic backgrounds, particularly those who regularly venture outside of the home. Many of the public toilets that are available were built with limited budgets and are poorly designed and maintained. While approximately 13% of the world’s female population lacks access to toilets, studies have put that number closer to 50% in India.
Each Woloo-enabled washroom follows a standard protocol to ensure safety, cleanliness and hygiene, which is based on a guideline developed by the Toilet Board Coalition, a global nonprofit enterprise, and the Woloo Assurance of Hygiene (WAH) based on safety, hygiene and accessibility parameters. Woloo maintains more than 1,500 washrooms across Mumbai, with plans to expand to Jaipur, Ahmedabad, Pune and Bangalore.
“Woloo’s mission is to provide hygiene dignity to a diverse group of women of all ages in India,” said Woloo founder/CEO Manish Kelshikar. “Our partnership with IWSH and IAPMO will certainly help in raising the standards of shared sanitation in India to world-class benchmarks. IWSH, IAPMO and its partners, and Woloo will work together and build trust in shared and public sanitation.”
IWSH has donated funding for 1,000 annual subscriptions, which will go to women of Mumbai’s Railway police force, and is contributing toward a public relations campaign promoting a new facility in the Ghatkopar Metro station in Mumbai. Ashirvad Pipes, Cera India and A.O. Smith India have generously donated IAPMO-certified products for the project. The 1,000-square-foot Woloo-PowderRoom Lounge will include eight smart toilets, a 14-seat café and a 600-square-foot retail area catering to women’s hygiene, personal care, intimate utility and beauty products. An exclusive preview was held Jan. 30.
The mission of Woloo, which opened its first facility Nov. 19, 2019 — World Toilet Day — is to provide world-class access to hygiene facilities for women of all ages and diversities across India.
“Lack of access to improved sanitation, especially out of the home, for women has remained a difficult problem to solve, leading to immense anxiety on one hand and continuing a high burden of disease on the other,” said Dr. Nimish Shah, managing director of IAPMO India Pvt. Ltd. “There are very few sustainable models that have successfully solved this problem. Woloo is a promising women’s hygiene and sanitation access platform that is taking this challenge head on. IWSH and IAPMO are proud to partner with Woloo in its mission to provide safe, clean and hygienic sanitation access for women. We believe that quality, certified hardware underpins the durability of improved sanitation, and Woloo powder rooms are perfect venues to demonstrate well-designed, hygienic public toilets.”

A Much-Needed Lesson?
Submitted By Peter McLennan
This article first appeared in the summer 2019 edition of Plumbing Connection Magazine. Their weblink is: www.plumbingconnection.com.au . The article was provided by the Backflow Prevention Association of Australia Incorporated. www.bpaa.org.au
A recent contamination event in New South Wales provided a lesson in backflow containment cross connections, contamination and leak detection.
Peter McLennan reports:
Backflow incidents happen more often than you probably think. But why do cross connections continue to happen when we have trained professionals working on our drinking water? Is it laziness, attention to detail or just plain ignorance?
A large New South Wales water utility recently experienced an unprecedented contamination event. Although no ongoing issues have been recorded, it highlights the potential for unrecognized contamination of the drinking water supply in both private on-site services and network infrastructure.
The contaminant: fluorescein, a brightly colored chemical product often used to identify leaks in sewers and rainwater systems. It is not made for use in drinking water as the following dictates:
Topical, oral and intravenous use of fluorescein can cause adverse reactions, including nausea, vomiting, hives, acute hypotension, anaphylaxis and related anaphylactoid reaction, causing cardiac arrest and sudden death due to anaphylactic shock.
The most common adverse reaction is nausea, due to a difference in the pH from the body and the pH of the sodium fluorescein dye; a number of other factors, however, are considered contributors as well. The nausea usually is transient and subsides quickly. Hives can range from a minor annoyance to severe, and a single dose of antihistamine may give complete relief. Anaphylactic shock and subsequent cardiac arrest and sudden death are very rare, but because they occur within minutes, a health-care provider who uses fluorescein should be prepared to perform emergency resuscitation. (Source: Wikipedia)
The investigation has identified two possible sources of contamination:
- Fluorescein may have been introduced to locate leaks in the newly installed fire service and interconnected pipework
- Uninstalled pipes and fittings may have been contaminated on site, during transport or a deliberate action
A new fire and domestic service was being installed in a public school, closed for the school holidays.
The fluorescein travelled through the new fire and domestic services into the existing domestic service, which had been cross connected for testing purposes.
The existing 40 mm water service and meter at the school did not have a backflow containment device in place, which allowed the fluorescein to travel into the network main, impacting several residential properties.
Tap testing of the on-site outlets, which included drinking bubblers, produced large volumes of colored water; fortunately, it was a school holiday period.
This cross-connection event, if not for the presence of the fluorescein, may have gone undetected and highlights the need for due diligence when working on drinking water supplies.
The introduction of contaminants into any water supply could have fatal outcomes, as experienced with historical cross-connection events.
Our community has a reliance on licensed plumbers and on-site regulators to support quality plumbing installations and help protect the drinking water supply used by the community.
The unprecedented growth in the construction industry underscores the need for better regulation and compliance standards.
The safety of the drinking water supply should be of paramount importance whenever plumbing work is carried out.
Backflow prevention and cross-connection control is integral to keeping the drinking water safe and ensuring the health and amenity of the public.
Plumbers need to keep up to date on regulations and standards so a continuing professional development programme is introduced to cover aspects like backflow prevention as soon as possible.

No More Waste: Plumbing Industry Launches PVC Recycling Scheme
As society moves its attention toward long-term sustainability, the Queensland plumbing industry has recognized its role in contributing to a responsible and sustainable future by diverting off-cuts of plastic pipes from landfills and recycling them into new pipes.
Master Plumbers’ Association Queensland (MPAQ) and Plastics Industry Pipe Association of Australia (PIPA), in conjunction with Iplex, Reece, Tradelink, and Vinidex, have joined forces to launch the Construction Plastics Recycling Scheme.
The Queensland government has provided funding support to ensure the delivery of the scheme’s six-month pilot program.
MPAQ Executive Director Penny Cornah said the Construction Plastics Recycling Scheme has been developed to help industry understand the volume of available PVC pipe off-cuts and fittings from construction sites.
“Our goal is to educate and change behaviors when it comes to the disposal of PVC off-cuts, which can be recycled into a new long-life recyclable pipe product,” Cornah said.
“This scheme highlights the environmental commitments of not only the partners involved but also the industry as a whole.”
The Construction Plastics Recycling Scheme officially began Nov. 1, 2021, with collection bins delivered to seven participating locations across South East Queensland, providing alternative outlets for PVC off-cuts to be discarded. The off-cuts collected in these bins during the scheme will be audited and data recorded.
Plastics Industry Pipe Association of Australia Executive General Manager Cindy Bray said most plastic pipes installed throughout Australia are 100% recyclable and can be easily reprocessed and manufactured into new pipe. Volume of plastic pipes in the waste stream are low due to their long service life, however waste, such as off-cuts generated during the installation process need to be captured and diverted from landfill. The Construction Plastics Recycling Scheme focuses on PVC non-pressure and pressure pipes and fittings.
“PVC pipe can be recycled six to seven times without significant reduction in pipe material quality requirements, highlighting the many benefits to collecting and recycling the off-cuts,” Bray said.
“Assuming a pipe lifetime of 100 years, the PVC material in PVC pipes may have a lifetime in excess of 600 years.”
Overall, the process of producing, recycling and reusing pipes has minimal environmental effects, highlighting the never-ending benefits of implementing the Construction Plastics Recycling Scheme.
Plastic pipes are smart, efficient and sustainable, providing long-lasting and reliable infrastructure both now and into the future.
Environment Minister Meaghan Scanlon said the Construction Plastics Recycling Scheme was a clear example of a “circular economy” in motion.
“As we move towards making Queensland a truly sustainable state operating on a circular economy – where waste is reduced and resources are recovered and re-used – initiatives such as the Construction Plastics Recycling Scheme can play a major role in achieving our goals,” Scanlon said.
An official launch event was held Nov. 12 at Reece Plumbing Supply Store in Labrador, with The Hon. Meaghan Scanlon MP, minister for the Environment and the Great Barrier Reef and minister for Science and Youth Affairs, attending the launch. For media inquiries, please see contacts below.

New Zealand Institute of Central Heating Partners with BPEC to Raise Standards
Driving best practice through training: raising the standard for the installation of Hydronic Underfloor Heating in New Zealand
BPEC, the leading provider of training, qualifications and assessment services for plumbing, heating and gas, has worked with the New Zealand Institute of Central Heating (NZICH) on a new training scheme designed to raise standards. There is no current regulation on standards for hydronic heating in New Zealand for installers and end users to work to, and check against, to ensure the best possible systems are installed.
“Our mission is to improve the industry through best practice and training,” says Paul Woodgate, NZICH secretary. “Working with BPEC, we now have an accredited Underfloor Heating (UFH) Installer One course that will provide installers with a four-year accreditation. It also means we can approach architects and builders to develop greater knowledge and understanding of the right ways to design and install UFH.”
NZICH is a community of industry leaders providing technical information and experience, representing those responsible for the design, installation, commissioning and maintenance of central heating systems.
BPEC is a specialized UK-based provider of industry-recognized qualifications, assessments, training courses and learning materials, providing services to colleges, private training centers, employers and learners across the plumbing, heating, gas and wider energy sector.
“I had previous experience of BPEC as an installer and also instructing on UFH courses, so I knew BPEC had a training program we could adapt,” Woodgate said. “They provided UK manuals and presentations to develop the New Zealand version, which covers all the main points in terms of British standards while adding the features that are unique to how houses are built here. BPEC was flexible in the technical language, to reflect the differences in New Zealand while ensuring the training content remained rigorous. We can now be consistent in the terms used.”
NZICH recently completed a pilot program with eight candidates undergoing training and assessment.
“We were keen to work with NZICH and help raise the standards of hydronic heating installation in New Zealand, an approach that aligns with our values,” said Mally Butters, BPEC’s business area manager. “We are looking forward to developing our relationship — working together can only benefit NZICH and the sector in New Zealand by improving quality and skills.”
