Unlocking the Benefits of Sanitary Waste Valves

Sanitary waste valves (SWVs) offer a compelling alternative to traditional p-traps for sporadically used locations such as vacation homes, guest bathrooms, dorms, stadiums, and seasonal facilities. Unlike p-traps, these devices provide permanent protection against sewer gas exposure, making them a valuable safety benefit in situations where water traps can evaporate.

This webinar helps plumbing engineers enhance their knowledge and expertise in the use of SWVs to prevent sewer gas exposure in buildings with sporadic or seasonal use. Participants will gain insights into the advantages, applications, and regulatory considerations associated with these valves, helping them stay up-to-date with industry trends and best practices. 

Learning Objectives:

• Understand the benefits of using inline sanitary waste valves for sink drains vs.  p-traps in sporadic use locations where the water seal in a p-trap can evaporate. Explain how SWVs provide permanent protection against sewer gas exposure and how the design enables vandal-resistant commercial installation and increased storage options.
• Appreciate how SWVs contribute to reduced stagnant water and the mitigation of viral and bacterial pathogens. Also review how SWVs promote more forceful drainline carry, an important consideration with many legacy piping systems oversized for today's low-water-use fixtures. 
• Learn about installation and maintenance best practices with inline sanitary waste valves. Routine or seasonal maintenance system flushing is unnecessary, nor technically is it necessary to use branch air admittance valves to protect it from siphonage.
• Navigate building codes and regulations. Summarize the building code approval status of inline sanitary waste valves in North America. Describe the relevant standards, such as ASME Standard A112.18.8 - 2020, governing the use of SWVs and their distinctions from traditional p-traps.
