Certification
Washlet are certified as plumbing device by assuring safety against backflow in
following manners:
-In Japan, USA and Asia: Backflow prevention performance
-In Europe: Backflow prevention device design
【Europe】Performance on backflow prevention must be assured by
construction. EN1717-based national standards
Germany: DVGW W540
UK: BS EN1717
There must be a physical “airgap” construction on the
primary side of connection or on the inside
【USA/Japan】
Performance on backflow prevention is evaluated by testing:
USA:ASSE1001
Japan: JIS S 3200-4, JIS S 3200-5
Same test method, different criteria
Requirements in each country

Introduction of TOTO Washlet
Black DeathSpread of the Black Death in Europe (1346–1353)The Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people in Eurasia and peaking in Europe in the years 1346–1353.Although there were several competing theories as to the etiology of the Black Death, analyses of DNA from victims in northern and southern Europe published in 2010 and 2011 indicates that the pathogen responsible was the Yersinia pestis bacterium, probably causing several forms of plague.
Why such strict requirements in EU?
EU proposed strict requirements in fear that this might happen again.

Risk of backflow in WashletNozzle unit
Overflow level of ceramic
Nozzle extends to the rim surface of bowl, and backflow can occur when 4 conditions are fulfilled simultaneously:
1) Toilet bowl is clogged2) Nozzle is extended3) Flow conduit is opened4) Negative pressure on primary side
Accumulated sales of Washlet products by
Japanese manufacturers exceed 100 million
units, but there has been no reported incident
of backflow-related accidents!

Airgap
Currently, there are only 2 options left for the manufacturers:-Installation with RPZ backflow device; or-Airgap construction in the water conduit to raise the overflow level

Question:If the vacuum breaker has the same level of backflow prevention performance as airgap construction, and if the reliability of the system is assured by product certification, could it be considered sufficient?

Proposal from TOTO
24
In order to help promote both water efficient plumbing fixtures and backflow prevention devices, we would like to make the following proposal:
A douche outlet installed at least 25mm above
the overflow level of the pan, at any position,
does not require an external backflow
prevention device;
Or if the device incorporates backflow
prevention constructions, its performance shall
be AS/NZS 2845.1 compliant.
If the douche outlets is less than 25mm above
the overflow level of the pan, at any position, a
“high hazard” backflow prevention device must
be installed unless the device incorporates an
AS/NZS 2845.1 or AS2845.2 compliant
backflow prevention device.
As evidence of compliance,
test by approved test labs and
conformity certificate (marking)
shall be required
For plumbing fixtures, backflow prevention performance should be required, and for devices that do not fulfill the requirements, installation of RPZ backflow prevention
device should be made available as an alternative option.Introduction of TOTO Washlet
