5. Title, number of pages and language(s) of the notified document:  WaterMark 
Certification Scheme - AS/NZS 2845 - Water supply - Backflow prevention devices, Part 
1: Materials, design and performance requirements. (87 page(s), in English)  
6. Descrip tion of content:  This technical specification sets out the requirements for the 
materials, design, performance and testing of mechanical backflow prevention devices 
that are used for the protection of water supplies. The backflow prevention devices 
covered  in this document are of the following types:  
(a) Atmospheric vacuum breaker (AVB).  
(b) Hose connection vacuum breaker (HCVB).  
(c) Dual check valve with atmospheric port (DCAP).  
(d) Dual check valve (Dual CV).  
(e) Dual check valve with intermediate vent (Du CV).  
(f) Pressure -type vacuum breaker (PVB).  
(g) Double check valve (DCV).  G/TBT/N/AUS/133

  (h) Double check detector assembly (DCDA).  
(i) Reduced pressure zone device (RPZD).  
(j) Reduced pressure detector assembly (RPDA).  
(k) Spill -resistant pressure  vacuum breaker (SPVB).  
(l) Beverage dispenser dual check valve with atmospheric port (BDDC).  
(m) Pipe interrupter device (PID).  
(n) Single check valve (testable) (SCVT).  
(o) Single check detector assembly testable (SCDAT).  
The Plumbing Code of Australia ( PCA) requires that most products intended for use in 
plumbing and drainage installations in or around buildings to be evaluated and certified 
to WaterMark product specifications. WaterMark certification to an applicable product 
specification provides a pro cess to evaluate and authorize products to enable their use in 
a plumbing and drainage installation. Thus ensuring that the plumbing and drainage 
products are fit for purpose for which they are intended.  
This WaterMark Technical Specification (WMTS) was pr epared in accordance with the 
Manual for the WaterMark Certification Scheme, Appendix 4, Protocol for Developing 
Product Specifications.  
The objective of  WaterMark Technical Specification is to enable product certification in 
accordance with the requiremen ts of the Plumbing Code of Australia (PCA).  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  The objectives of the Scheme are to establish the requirements for product 
certification and authorisation under Part A2 of the PCA and:  
a) to provide a process to authorise products to enable their use in plumbing and 
drainage installations as covered by  the PCA, and  
b) to ensure that plumbing and drainage products are fit for the purpose for which they 
are intended and that their use in a plumbing and drainage installation throughout its 
serviceable life is suitable and does not create significant risks or any likely outcome of:  
 (i) personal illness, loss, injury or death;  
(ii) on -site environmental degradation;  
(iii) contamination of the water resource;  
(iv) adverse impact on infrastructure (private or public);  
(v) contamination of water supplies from the point of connection to the points of 
discharge; or  
(vi) wastage of resources (water and energy);  
Protection of human health or safety; Protection of the environment; Quality 
requirements

9. Proposed date of adoption:  2 May 2022 ; This date is indicative only.  
Proposed date of entry into force:  2 May 2023 ; There is a 12 month transition 
timeframe for existing certifications. New certifications MUST co mply from the date of 
adoption.
