Tempering Valve

Overview
Our Tempering Valve is the unsung hero of every plumbing system—blending hot and cold to deliver a perfectly tempered flow. Available in four configurations (12 mm, 12 mm High Performance, 20 mm, and 20 mm High Performance), it eliminates scald risks, protects fixtures, and keeps everyone from six-year-olds to great-grandparents happy in the shower (and at the sink).

Why a Tempering Valve Matters

• Safety First: Prevents water from ever exceeding unsafe temperatures at points of use (escaping scalded eyebrows is a win).
• Code Compliant: Meets Australian Standard requirements for potable water installations.
• Fixture Protection: Limits outlet temperature to protect your taps, mixers, and hot-water systems from heat stress.
• Whole-House Comfort: Whether it’s a quick handwash or an all-day bath party, enjoy a consistent water temperature every time.

Which Variant Is Right for You?

• Standard (12 mm / 20 mm): Reliable tempering for most residential installs.
• High Performance (HP): Includes a wrap-around polyurethane insulation jacket to minimise heat loss, ward off freezing in cooler months, and boost energy efficiency.

Key Features (All Variants)

• SharkBite® Push-Fit Inlets (and Outlets on HP Models): Installs in seconds—no soldering, clamps, or glue. Trade-friendly, DIY-approved.
• Dezincification-Resistant Brass Body: Built tough for Australian water conditions, ensuring lasting performance.
• Internal Strainer & Check Valves: Protects the valve from debris and prevents backflow contamination (goodbye nasty surprises).
• Tamper-Proof Adjustment Nut: Once dialled in, the outlet temperature stays locked—no wandering thermostats due to curious fingers.
• Factory-Calibrated Accuracy: Each valve is performance-tested at our source, guaranteeing reliable outlet temperatures out of the box.

High Performance (HP) Extras

• Polyurethane Insulation Jacket: Keeps heat where it belongs—inside the valve—reducing energy loss and preventing freezing in cooler climates.
• SharkBite® Outlets: On 12 mm HP and 20 mm HP models, both inlets and outlets feature SharkBite push-fit connections for maximum installation speed.
• Ideal for Solar & Tankless Systems: Handles fluctuating inlet temps without losing its cool.
