🧨 Non-Conformance Risks and Legal Exposure
Converting standard urinals into waterless systems using Desert’s non-certified cartridges may:
❌ Breach the National Construction Code and AS/NZS 3500
❌ Void plumbing warranties and commercial insurance policies
❌ Trigger legal action if performance fails or damage occurs
Despite Desert’s claims, non-compliant installations have shown:
❌ Increased risk of bacterial growth due to inadequate drainage
❌ Persistent foul odours that compromise hygiene and facility standards
❌ Greater risk of patron complaints and regulatory scrutiny
⚠️ While no direct medical cases have been linked to Desert cartridges, the conditions they create are unsanitary and in breach of public health best practices.
Businesses using Desert cartridges expose themselves to serious consequences under compliance laws such as:
♻️ The Queensland Building and Construction Commission (QBCC) Act requires mandatory reporting of non-compliant plumbing products
♻️ Plumbing Code of Australia and WaterMark schemes – installation of uncertified products is strictly prohibited
❗ Industry experts widely label Desert’s claims of universal compatibility and certification as misleading.
Facilities relying on these claims may be liable for any failures or complaints. Being cautious and not taking these claims at face value is crucial.
🏛️ Regulatory Violations and Safety Failures
Since the 2010 amendments to the Plumbing Code of Australia, converting water-flushing urinals to waterless systems without certification is prohibited.
Desert Eco Solutions exploited regulatory gaps during Australia’s drought years by retrofitting uncertified systems pre-2010, many of which remain in operation illegally today.
A significant injury case, Kim Domjahn v. Australian Scholarship Group Friendly Society Ltd and Planet Earth Holdings Pty Ltd, highlights the severe consequences of Desert’s retrofitting practices. Represented by Tulin Terzioglu of Melbourne Injury Lawyers, Kim Domjahn suffered severe respiratory issues after his employer instructed him to unblock urinals retrofitted with Desert Eco cube products.
These urinals, allegedly converted without certification by Desert Victoria, became blocked due to uric salt buildup. Despite having no plumbing license, Domjahn was tasked with maintenance. Ultimately an unsafe directive that resulted in his injury.
Desert Victoria later responded to Melbourne Injury Lawyers in a letter dated 28 July 2016, denying liability and blaming poor cleaning practices for Domjahn’s injuries. However, expert analysis supports that the blockage risk is intrinsic to the system: urine’s composition (96% water, 4% salts) naturally leads to scale and failure. Desert’s so-called microbial technology fails to mitigate this.
The case was ultimately settled out of court, avoiding full public disclosure but confirming the seriousness of the incident and its implications for employers and facility managers.
The blockages foster severe odour and bacterial growth. Desert’s “Deep Clean Service” omits the high-pressure jet rodding required to maintain hygiene, especially in busy commercial sites.
When Whywait Plumbing publicly challenged Desert’s legality and safety, Desert’s lawyers — including Stephen Dickinson of Wallmans Lawyers – issued threatening letters demanding content takedowns.
Desert never responded when asked to substantiate its product’s compliance in response to these challenges.
Under Australian Consumer Law, businesses using non-compliant Desert cartridges are entitled to refunds and complete remediation. This includes compensation for damage or excessive maintenance costs.
⚠️ These aren’t just regulatory breaches – they’re health risks, legal threats, and proof of systemic failure to meet Australian plumbing standards.
🔍 What Is the Desert No Flush Cartridge?
The Desert No Flush Cartridge, also known as the Desert Eco Adapt Cartridge, is marketed as a universal solution for waterless urinals. According to its advertising, it can replace cartridges in the following brands:
This bold compatibility claim is not only misleading but also legally dangerous. None of these brands has independently verified or endorsed the Desert cartridge. Furthermore, no valid certification confirms it functions correctly within their proprietary systems.
❗ This isn’t just a technical mismatch — it’s a compliance violation. Unverified substitution of components in regulated plumbing systems breaches Australian Standards and exposes facilities to potential failures, odour issues, and legal consequences.
These universal fit claims are designed to mislead facility managers and plumbers into believing the cartridge is a plug-and-play solution. It’s not.
📋 False Claims & Outdated Certifications
🟥 View 2019 Expired Certificate
🟥 View 2016 Certificate – Also Outdated
These certificates are invalid under current plumbing compliance standards and cannot legally support installation.
Desert’s marketing relies heavily on outdated and misleading WaterMark certification claims. Their website displays a WaterMark Level 2 certificate that expired in November 2019, and for two whole years, they operated without valid certification.
In late 2021, Desert obtained a new WaterMark certificate, which was granted under an outdated testing standard, no longer aligned with current NCC and PCA compliance expectations.
⚠️ Crucially: No Australian manufacturer listed, including Uridan, Caroma, and Zero Flush, has a WaterMark Certificate of Conformity, including the Desert cartridge. That means these manufacturers do not approve or recognise it.
This is more than a paperwork issue. Without current, standards-compliant certification, this product fails legal installation requirements. Using it could mean:
🧑⚖️ Immediate breach of AS/NZS 3500 and NCC plumbing compliance
🧑⚖️ Possible insurance voidance for plumbing failures
🧑⚖️ Legal liability for damage or health complaints linked to improper function
🔍 Bottom line is that the Desert No Flush Cartridge is not certified, recognised, or safe for installation in any compliant plumbing system. Using it could immediately breach AS/NZS 3500 and NCC plumbing compliance, possibly void insurance coverage for plumbing failures, and expose legal liability for damage or health complaints linked to its improper function.
This section above of Desert’s website is pure fiction — aside from possibly being Australian-owned. The claims made are unverified, unsupported by evidence, and contradicted by independent inspections, WaterMark certification records, and urinal manufacturer guidelines.
🧪 Unsupported Marketing Claims and Deceptive Practices
Desert claims its cartridges last up to 12 times longer than competitors’ and are recyclable. However, there is no independent evidence to support this lifespan claim, nor are there details on third-party recyclability or environmental impact testing.
Desert says their cartridges are cleaned and hygienically sanitised after every service. However, there are no published cleaning standards, test results, or validation from independent authorities to prove hygiene compliance.
Desert promotes quick installation by its technicians, yet fails to clarify whether those technicians are licensed plumbers. Under Australian law, only licensed professionals can legally perform urinal installations. Marketing suggests ease and speed, but likely conceals non-compliant practices.
🚨 None of these claims are backed by verifiable data or compliant practice. Relying on them could expose your business to regulatory breaches and maintenance risks.
🚨 Exposing Desert's Misleading Marketing Claims
This is a complete lie. The Desert cartridge does not hold WaterMark certification for any brands it lists. No independent urinal manufacturer endorses it for use in their systems. This claim misleads buyers into believing it is legally compliant — it is not.
Desert claims its cartridge improves your NABERS water rating by reducing water use. Yet, they provide no case studies, data, or methodology to support this. No published evidence shows that any installation of Desert cartridges has measurably improved NABERS scores.
Desert claims its cartridge introduces beneficial microbes that reduce scale and extend pipe life. However, this claim is scientifically unsubstantiated and unsupported by testing. In real-world conditions, these cartridges are more likely to cause blockages, odours, and increased maintenance, not less.
⚠️ Bottom Line: These claims are designed to create a false sense of confidence. None are backed by independent testing or legally recognised documentation. Don’t be fooled by marketing spin when your compliance and budget are on the line.
❌ Not WaterMark Certified for Use in Australia
Desert’s product is not legally compliant in Australia. Under the mandatory requirements set out in the National Construction Code (NCC), the Plumbing Code of Australia (PCA), and AS/NZS 3500:
✅ All plumbing products must be WaterMark certified
✅ Non-conforming products cannot be lawfully installed
✅ Any breach exposes plumbers and facility managers to legal penalties
📛 There is no grey area. Installing an uncertified cartridge breaches Queensland plumbing laws and exposes everyone to severe liability.
By installing the Desert No Flush Cartridge, you risk:
❌ Immediate breach of Plumbing and Drainage Act 2018, AS/NZS 3500 and National Construction Code Part 3
❌ Failure to comply with the Queensland Plumbing and Drainage Regulation 2019, Queensland Plumbing and Wastewater Code
❌ Enforcement action by the QBCC or local government
📈 Using a cartridge without certification voids warranties, breaches legal obligations, and can lead to expensive repairs and prosecution.
Relevant Legal Resources:
✅ WaterMark Certification Scheme
✅ National Construction Code (NCC)
✅ Plumbing Code of Australia
✅ AS/NZS 3500 Plumbing and Drainage Standards
✅ Plumbing & Drainage Act 2018
⚠️ Misuse Can Lead to Health and Legal Risks
When you install a non-compliant cartridge like the Desert No Flush model, you risk legal repercussions and compromise the health and safety of every person using that facility.
Concealed health dangers include:
❌ Bacterial contamination from unsealed waste lines
❌ Persistent unpleasant odours that deter use and damage brand image
❌ Hygiene complaints from patrons or staff, especially in public venues and commercial spaces
Why it happens: These cartridges lack the tested barrier mechanisms that properly block rising sewer gases and bacteria-laden vapours. Without certified sealing and performance, every flush-free urinal becomes a potential biohazard.
Legal consequences include:
❌ Substantial fines for installing and using non-compliant products
❌ Breaches under the Plumbing & Drainage Act 2018, QBCC Act and Plumbing & Drainage Regulation 2019
❌ Risk of civil liability for illness, workplace complaints, or property damage linked to odour or leaks
🧪 The smell is just a warning. Pathogens don’t always have a scent. If you’re getting complaints about urinal odours, you may expose users to unseen bacteria.
The Desert cartridge is not engineered to meet the rigorous product compliance and health protection requirements of WaterMark requirements and Australian standards of any urinal other than their own Desert No Flush Urinal, making its use irresponsible and potentially unlawful.
💉 Regular complaints about odour are often traced back to these non-compliant cartridges. Don’t wait until someone gets sick before you act.
📜 The Law Is Clear: Use Compliant Products Only
All plumbing work and parts installed in Queensland must legally comply with:
✅ Plumbing & Drainage Act 2018
✅ Plumbing & Drainage Regulation 2019
✅ AS/NZS 3500
✅ Queensland Plumbing and Wastewater Code
✅ NCC (National Construction Code)
✅ PCA (Plumbing Code of Australia)
Desert No Flush Cartridges do not meet any of these legal requirements.
❌ Don’t risk it. If it’s not WaterMark certified, it’s not legal – and it’s not safe.
🧑🔧 Only Licensed Plumbers Can Install or Service Urinals in Queensland
In Queensland, only QBCC licensed plumbers may legally install, service and maintain water-flushing or waterless urinals. DIY installation or using non-licensed contractors is illegal.
There is no such QBCC licence for a:
❌ Desert Certified Urinal Technician
Proper installation and maintenance by licensed plumbers ensures:
✅ Compliance with plumbing standards and legislation
✅ Correct connection to sewer infrastructure
✅ Health and safety protection for all users
