FAQs
What is the default temperature setting?
The valve is pre-set to 38ºC to provide a safe and comfortable baseline for users.
Can I increase the temperature above 38ºC?
Yes, there is a built-in safety override switch that allows the temperature to be adjusted up to a maximum of 45ºC.
Does this valve work with electric showers?
No, this is a thermostatic mixer valve designed to mix separate hot and cold water supplies; it is not an electric shower unit.
Is it difficult to install?
Because it is a concealed unit, it requires wall preparation and precise plumbing connections, so professional installation is strongly recommended.
Will this protect against sudden cold water drops?
Yes, the thermostatic element is designed to shut off or stabilize the output if the cold water supply fails or fluctuates significantly.
How do I maintain the valve?
Keep the external handle clean with a damp cloth and perform annual inspections of the inlet filters to prevent mineral deposits.
Troubleshooting
Water temperature fluctuates during use
Check the inlet filters for sediment buildup or verify that the hot water supply pressure is sufficient.
Water will not get hot enough
Ensure the thermostat override button is correctly engaged and not blocked by debris or scale.
Low water flow rate
Inspect the plumbing lines for any partially closed isolation valves or blockages within the cartridge.
Pros and Cons
Pros
- High level of safety against accidental scalding
- Maintains constant temperature even if other taps are opened
- Sleek concealed installation for a modern look
- Adjustable temperature range up to 45ºC
- Sturdy construction for long-term reliability
Cons
- Requires professional plumbing installation
- Wall access may be needed for future maintenance
- Not suitable for low-pressure gravity-fed systems without a pump
Setup, Compatibility & Care
Installation should be performed by a qualified plumber to ensure the hot and cold inlets are connected correctly and the unit is pressure-tested before the wall is sealed. The valve is compatible with most standard residential hot water systems, provided they meet the pressure requirements of the manufacturer. For care, avoid using abrasive cleaners on the control handle to preserve the finish. If the temperature becomes inconsistent over time, check the inlet filters for debris, as mineral buildup can restrict water flow and impact the thermostat's sensitivity.
