Facts about New Zealand’s tough plumbing regulations.
The New Zealand Building Code has stringent plumbing regulations for the installation of electronic bidets.
Unfortunately most bidets installed in New Zealand fall short. Most bidets in New Zealand are imported from South Korea, China or Japan often via Australia, and are either sold without any backflow prevention, or with a double/dual checkvalve, which may comply with Australian law, but not New Zealand law. Because bidets connect with the potable water supply, the law requires that an RPZ type valve be used for non compliant bidets. This valve offers the highest degree of protection as required for a “high hazard” appliance which an electronic bidet is.
Unfortunately these valves are expensive and unsightly.
The responsibility for compliance falls to the installer of the bidets, which means that anyone can sell non complaint bidets without disclosing the additional RPZ valve requirement. Unfortunately most plumbers and sellers are unaware of this requirement.
The picture below is one of the appropriate valve that was recommended for use for the non compliant bidet by a plumbing merchant.
Typical RPZ VALVE
Valves like the below are NOT APPROVED for use with electronic bidets under the current plumbing regulations.
The Cleanlet does not require any of the above valves as the
Cleanlet bidet has the backflow prevention built into the unit
The Cleanlet bidet is currently the only bidet in New Zealand which does not require an external RPZ valve to comply with the New Zealand Building Code (because the backflow prevention is built into the bidet) We believe that plumbers, the plumbing merchants and the general public should be informed as to the plumbing regulations relating to electronic bidets within the Building Code.
