Thermostatic Mixing Valves
Hot water safety is paramount in facilities like hospitals, aged care centres, gyms, and even commercial kitchens. Thermostatic Mixing Valves (TMVs) are specially designed valves that blend hot and cold water to a pre-set safe temperature, preventing scalding at taps and showers. MPJ Plumbing Group offers complete TMV services in Sydney, from professional installation of new TMVs to mandatory annual testing and maintenance of existing valves. If you have a commercial or public building, chances are you have TMVs in your plumbing system to comply with Australian Standards for hot water delivery (typically max 50°C for most outlets, or 45°C in care facilities). Our licenced plumbers are trained and accredited in TMV maintenance, ensuring your valves function correctly and deliver water at consistent temperatures. With MPJ’s help, you can provide comfort and safety in your bathrooms and kitchens, and meet all regulatory requirements for hot water systems.
Our TMV Services
TMV Installation
Routine Testing & Certification
MVs in commercial settings (like childcare centres, schools, nursing homes, etc.) must be tested and certified annually by a qualified plumber to comply with NSW health regulations and Australian Standard AS4032.3. MPJ Plumbing Group provides this annual testing service. During a TMV test, we measure the outlet water temperature to verify the valve is controlling correctly. We also shut off the cold supply briefly to ensure the valve’s failsafe works (the hot flow should shut off if cold fails, to prevent scalding). Each valve is stripped, cleaned, and inspected internally – we remove scale or debris, check the condition of internal thermostatic elements and seals, and replace any worn parts or O-rings. After reassembling, we recalibrate the valve to the correct temperature. We then issue a test report and compliance certificate for your records, noting each valve’s condition and test results.
Repairs & Replacements
If a TMV is found to be faulty or performing poorly (for instance, if it can’t hold the set temperature or is stuck), our plumbers will repair it if possible. We carry common TMV spare parts – like thermostat cartridges and seals – to get valves working again on the spot. If a valve is beyond repair or very outdated, we can replace it with a new unit. We’ll handle everything from sourcing the right model to installation and disposal of the old valve.
System Balancing & Consultation
Sometimes, issues with temperature can be due to factors around the TMV – like incorrect plumbing configurations, or fluctuating pressure/temperature from your hot water system. We provide advice and modifications beyond the valve itself, such as installing pressure limiting valves, ensuring hot water units are set to the right storage temperature (usually 60°C or higher to prevent Legionella, which the TMV then mixes down), and making sure recirculating hot water loops are functioning (so that hot water is quickly available at each TMV). This holistic view means that your entire hot water delivery system is safe and efficient, not just the TMVs.
Why Use MPJ for TMVs?
Accredited TMV Plumbers
Working on thermostatic mixing valves requires specific training due to the safety implications. Our team includes plumbers who are accredited in TMV installation and testing. We follow the proper protocols and checklists every time, giving you confidence in our results.
Attention to Detail
TMVs are precision devices. We pay close attention when servicing them – even a small bit of grit can affect performance. MPJ plumbers meticulously clean and recalibrate each valve. This detail-oriented approach means your facility’s water temperature remains stable and safe.
Records Management
Records Management: We help you stay on top of compliance by keeping records of when your next service is due. Our team can remind you each year when it’s time to test your TMVs, so you’ll never miss a compliance deadline. We also label each valve with the last service date, making on-site audits straightforward.
Quality Products
If we’re installing or replacing TMVs, we use trusted brands that are WaterMark certified and known for reliability. A good TMV can last many years with proper maintenance. We make sure you get that longevity and value by choosing the right product for your usage level.
Integrated Plumbing Support
Because we are full-service commercial plumbers, we can handle any ancillary work that might come up during TMV service. For example, if a tap outlet is also faulty or a hot water circulating pump isn’t working (affecting TMV performance), we can fix it during the same visit. Our broad expertise ensures all aspects of your hot water system work in harmony.
