Thermostatic Plumbing Products

Q: How often do thermostatic mixing valves need to be serviced?

Thermostatic mixing valves should be tested and calibrated regularly in accordance with applicable Australian Standards, manufacturer requirements and the facility's Legionella risk management plan. Healthcare facilities commonly require regular temperature and thermal shutdown testing. Maintenance should be carried out by an appropriately licensed plumber where required.

Q: Are there accessible tapware options in the Gentec thermostatics range?

Yes. Gentec TEMPSET models including MVPMLF30150 and MVPMLF10150 feature 150mm lever handles. The wall-mounted MVPMLF20AV provides an anti-ligature control option for secure and mental health environments. Confirm mounting height, projection and reach requirements against the applicable accessibility requirements for the project.

Q: What is a thermostatic mixing valve?

A thermostatic mixing valve, or TMV, automatically blends hot and cold water to deliver a preset safe outlet temperature. TMVs are commonly used for scald protection and temperature management in commercial, healthcare and institutional hot water systems. Gentec's FLOMIX range provides thermostatic mixing valve products for these applications.

Q: Are lead-free thermostatic taps required in Australia?

Lead-free requirements apply to drinking water tapware under the applicable NCC and WaterMark requirements. For newly manufactured drinking water tapware, the applicable Lead-Free WaterMark requirements should be confirmed against current NCC provisions and the WaterMark Product Database.

Q: What does NSW Health Approved mean for thermostatic valves?

NSW Health Approval indicates that the applicable valve has been assessed for suitability under the relevant NSW Health requirements for use in NSW public hospital and healthcare premises. Specifiers should confirm the current approval status of the specific product before including it in a project specification.

Q: What Australian Standard applies to thermostatic mixing devices?

AS 4032.1 applies to thermostatic mixing devices for water supply. AS 3718 covers general tapware requirements and AS/NZS 4020 covers products intended for use in contact with drinking water. Project specifications should confirm the current edition and applicable amendments.

Gentec Australia’s thermostatic plumbing products deliver precision temperature-controlled water for environments where scald prevention and Legionella risk reduction are mandatory. The range spans three families: TEMPSET Lead-Free DZR Brass point-of-use thermostatic mixing taps for healthcare basin, shower and hob applications; Thermostatic Mixer Taps for wall, hob and in-wall installations; and thermostatic mixing valves -including the FLOMIX range and the broader Thermostatic Mixing Valves category -for zone-level, NSW Health Approved hot water conditioning in hospitals, aged care and institutional buildings. All families are manufactured from dezincification-resistant (DZR) brass with a chrome-plated finish, meeting AS 3718:2021 and AS/NZS 4020:2018 requirements. Specifiers sourcing mixing valves for centralised or zone-level Legionella management should explore the Thermostatic Mixing Valves or FLOMIX ranges; those requiring visible point-of-use control at individual basins or showers should explore TEMPSET.

Why specifiers choose Gentec

Lead-Free DZR Brass construction: Dezincification-resistant alloy reduces risk of pitting and pinhole leaks in recirculated hot water systems, unlike standard brass fittings.
NSW Health Approved thermostatic mixing valves: Independently audited approval required for specification into NSW public hospital and aged care projects – not available on all competitor TMVs.
Chrome-plated finish: Provides a hard, cleanable surface compatible with healthcare-grade disinfectant protocols, including quat-based and hypochlorite cleaners.
Laminar flow at outlet (TEMPSET range): Reduces aerosol generation at point-of-use -a documented Legionella risk mitigation measure referenced in ASHRAE 188 and NSW Health guidance.
Integrated point-of-use thermostatic cartridge (TEMPSET): Eliminates the need for a separate zone valve by housing the thermostatic element directly within the tap body.
ISO 9001 certified manufacturer: Product quality is audited under an ISO Type 5 certification scheme with third-party surveillance at regular intervals.

Which tapware is right for my project?

Choose TEMPSET
Your project requires point-of-use thermostatic mixing taps at individual basins, showers or hob positions with an integrated mixer and lever handle – healthcare wards, aged care bathrooms, education facilities.

Choose Thermostatic Mixing Valves/FLOMIX
Your project requires a centralised or zone-level thermostatic mixing valve with enclosure, copper tails and NSW Health Approval, installed in a wall cavity or plant room rather than at the point of use.

Choose Thermostatic Mixer Taps
Your project needs a wall, hob or in-wall-mounted thermostatic mixer tap with an integrated body, distinct from the TEMPSET point-of-use model range.

How to Choose

Identify the installation position – Basin, shower or hob outlet at the user’s point of use → choose TEMPSET. Hidden valve in a wall cavity serving a zone → choose the Thermostatic Mixing Valves range (FLOMIX).
Confirm the regulatory environment – NSW public hospital or healthcare facility → an NSW Health Approved valve is required. All Australian projects after 1 May 2026 → Lead-Free WaterMark mandatory for newly manufactured product.
Check access and maintenance requirements – Recessed installations with a lockable stainless steel enclosure → FLOMIX MVLF60153/60154 series. Open wall- or hob-mounted tap → TEMPSET MVPMLF30150/10150 series.
Assess vulnerable-user requirements – Anti-ligature environment (corrections, mental health) → MVPMLF20AV. DDA/AS 1428.1 accessible bathroom → confirm 150 mm lever length (MVPMLF30150 and MVPMLF10150).
Specify and document – Download the datasheet and line drawing from the Gentec product page. Confirm WELS registration number, WaterMark licence number and lead content percentage before including in a specification schedule.

Thermostatics FAQ's

Do Gentec thermostatic products carry Lead-Free WaterMark certification?

Gentec’s TEMPSET, Thermostatic Mixer Tap and Thermostatic Mixing Valve (including FLOMIX) ranges are manufactured from Lead-Free DZR Brass and described as Lead-Free on product listings. Lead-Free WaterMark certification -required for newly manufactured drinking water tapware under NCC 2022 from 1 May 2026 -should be confirmed against the WaterMark Product Database at watermark.gov.au using the product’s licence number. Contact Gentec at info@gentecaustralia.com.au or (02) 9319 4422 for current documentation.

Can Gentec thermostatic mixing valves be used in aged care facilities?

Yes. Gentec’s thermostatic mixing valves, including the FLOMIX and Thermostatic Mixing Valves range, are suitable for aged care specification and carry NSW Health Approval. They are designed for institutional hot water systems where AS 4032.1 scald prevention (≤45°C at point of use for vulnerable persons) and Legionella risk management protocols must be met. Gentec states a five-year warranty on this range, and the recessed stainless steel enclosure with lockable lid on selected models satisfies tamper-resistant installation requirements common in aged care bathroom designs across Australia.

What is the difference between MVPMLF30150 and MVPMLF10150?

The MVPMLF30150 is a wall-mounted point-of-use thermostatic mixing tap with a 150mm lever; the MVPMLF10150 is a hob-mounted version with the same lever. Both are Lead-Free DZR Brass chrome-plated TEMPSET models with laminar-flow outlets, satisfying AS 4032.1 scald protection requirements. Choice depends on the basin or sanitaryware configuration: wall-mounted installations typically pair with semi-recessed or wall-hung basins, while hob-mounted suits counter-top or inset basins. Confirm rough-in dimensions from the individual product datasheet before finalising the hydraulic layout.

How often do thermostatic mixing valves need to be serviced?

Thermostatic mixing valves under AS/NZS 3500 and AS 4032.1 must be tested and calibrated regularly – typically every 12 months in healthcare settings or as specified in the facility’s Legionella risk management plan. The test verifies the mixed water temperature stays within ±2°C of set point and the thermal shutdown function operates correctly if cold water supply is lost. In several Australian states and territories, including the ACT, NSW, NT and QLD, this testing and maintenance must be carried out by an appropriately licensed plumber.

Are there accessible tapware options in the Gentec thermostatics range?

Yes. TEMPSET MVPMLF30150 and MVPMLF10150 carry 150mm lever handles, meeting the lever-length reference in DDA/AS1428.1:2009. The wall-mounted MVPMLF20AV provides an anti-ligature control for secure and mental health environments without requiring a separate product category. Verify mounting height against AS1428.1 for full DDA compliance, and confirm the selected model’s projection dimensions match the project’s accessible reach zone before finalising the specification schedule.

What is a thermostatic mixing valve?

A thermostatic mixing valve (TMV) is a device that automatically blends hot and cold water to deliver a preset safe outlet temperature, protecting users from scalds and reducing Legionella risk in commercial and healthcare hot water systems. Gentec Flomix range offers fit to purpose products.

Are lead-free thermostatic taps required in Australia?

Yes. Under NCC 2022 Clause A5G4(2), manufacture of non-lead-free WaterMark tapware is prohibited from 1 May 2026; existing WaterMark stock may still be installed until 1 May 2028. Lead-Free WaterMark certification is required for new drinking water tapware.

What is the difference between a thermostatic mixing tap and a thermostatic mixing valve?

A thermostatic mixing tap integrates the thermostatic cartridge within a visible tap body at the point of use. A thermostatic mixing valve is a standalone valve, usually installed in a wall cavity or plant room, that conditions water for a zone or circuit serving multiple outlets.

What does NSW Health Approved mean for thermostatic valves?

NSW Health Approved means the thermostatic mixing valve (TMV) has been approved by NSW Health for use as part of warm-water systems in NSW hospitals. The approval process assesses the TMV against NSW Health’s applicable approval requirements, including relevant performance, safety and installation requirements.

NSW Health requires warm-water systems installed in hospitals to be of a kind approved in writing by the Secretary. When approval is granted, the applicant receives an approval letter specifying the applicable conditions

What Australian Standard applies to thermostatic mixing devices?

AS 4032.1:2005 governs thermostatic mixing devices for water supply. AS 3718:2021 (Amdt 1:2024) covers general tapware performance and AS/NZS 4020:2018 governs material safety for drinking water contact.
