Plumbing Efficiency: Trap Primers & Arrestors with SMS

Chapter 1: Introduction to ATS and Trap Primers

• Zach Allison introduces ATS University, a webinar series focused on products available on the ATS spec tool.
• The ATS spec tool is a product selection and configuration tool for various products.
• ATS helps users set up the spec tool, manage firm masters, and implement the tool into their workflow, while manufacturer partners provide product training.

Chapter 2: Trap Primers and National Plumbing Code

• Owen Dwire introduces the topic of trap primers and water hammer arresters, focusing on education rather than sales.
• The national plumbing code mandates provisions for maintaining the trap seal of a floor drain.
• Traps prevent sewer gases from entering occupied spaces by maintaining a water seal.

Chapter 3: Trap Primer Types and Selection Considerations

• Trap primers include pressure-activated, electronic, and flow-activated types.
• Pressure-activated primers activate with pressure changes, but may be over-specified due to low-flow fixtures and booster pumps.
• Electronic trap primers use electricity to open a solenoid, offering water-conscious operation suitable for high-volume or infrequent-use scenarios.

Chapter 4: Back Siphonage Protection and Code Updates

• Air gaps are essential for potable water protection with trap primers, but the ports on pressure drop or flow-through devices are insufficient.
• The CSA B64-10-17 standard requiring additional zone protection for atmospheric vacuum breakers has been withdrawn and replaced by CSA B64-10-23.
• Atmospheric vacuum breakers are now recognized and suitable for minor, moderate, and severe applications, removing the need for additional zone protection.

Chapter 5: Water Hammer Arresters and ATS Spec Tool

• Water hammer is caused by the abrupt stop of liquid flow in a piping system, creating destructive forces.
• Water hammer arresters control shock by using a piston or bellows to compress air or nitrogen, and are sized based on fixture units.
• The ATS spec tool allows users to select trap primers and water hammer arresters, providing accurate model numbers, alternatives, and up-to-date information, and offering various specification formats.
