Abbreviations used: PRV = Pressure reduction valve / Pressure limiting valve, NRV = Non return or check valve

Select In + Out Tubing Size [Based on Outside Diameter] and KPA Pressure Rating From Drop Down Selection Menu

Can be fitted in line with any water filter system and uses quick-fit push in connectors to 1/4" [6mm] or 3/8" [10mm] tubing

High quality certified item manufactured in New Zealand according to Watermark and AS3497 quality standards

Required for AS3497 compliant fitment + lengthens the life of your water filter system by reducing pressure on the housings

ANTI LEAK DETECTION AND SHUT OFF DEVICE

NB: The 1/4" option in the drop down selection menu is by far more common and is to fit water filter tubing with an outside diameter or 6mm whereas the 3/8" option is for tubing with an outside diameter or 10mm

We recommend that a leak detector shut off device is installed with any water filter and / or reverse osmosis system which is under pressure.

• Stops major damage to your cupboards, floor or home by cutting off water supply to filter [connect after PRV]
• Uses replaceable sensor pads to detect leaks and it is recommended to replace the sensor pads every 12-months or after a leak
• Works on hydrophilic and mechanical principles and does not require power
• No batteries or electronic sensors required
• Proven track record with operating pressure range of 50-700kpa [7-100psi]
• Quick connect fittings to easily install in line with your 1/4" | 3/8"tubing
• Comes with 2 sensor pads

Why Choose the APEX FILTAMATE Water Pressure Reducing + Back Flow Prevention Device and Anti Leak Detection and Shut Off Device?

This product combines two of the most critical components for the safety, compliance, and longevity of your water filtration system: an APEX FILTAMATE Pressure Reducing Valve (PRV) with Back Flow Prevention (NRV) and a separate Leak Detection and Shut Off Device. The PRV/NRV is legally required for systems under constant pressure to meet AS3497 quality standards, actively protecting your filter housings and extending the system's life by reducing pressure. The Leak Detection Device offers peace of mind by preventing catastrophic water damage in your home.

Compact Design and Powerful Performance

The APEX FILTAMATE PRV + NRV is a high-quality, Watermark and AS3497 certified device manufactured in New Zealand. It serves a dual function by limiting the water pressure (PRV) on your filter system and preventing contaminated water from flowing back into the mains supply (NRV). This unit is customizable, allowing you to select the specific tubing size (1/4" or 3/8") and the desired KPA pressure rating from the drop-down menu, and it uses quick-fit push-in connectors for easy in-line installation.

The Anti Leak Detection and Shut Off Device is a highly reliable safety feature that works on hydrophilic and mechanical principles, meaning it requires no power, batteries, or electronic sensors to operate. It detects leaks using replaceable sensor pads and mechanically cuts off the water supply to the filter, stopping major damage to your home. It has a proven track record with an operating pressure range of $50\text{kPa}$ to $700\text{kPa}$ ($7\text{psi}$ to $100\text{psi}$) and comes with two sensor pads.

Seamless Integration and Easy Maintenance

Both devices are designed for easy fitting in-line with your existing water filter or RO system. The PRV/NRV ensures regulatory compliance and system longevity, while the mechanical leak detector provides robust, power-free protection against major water damage. The leak detector is recommended to be connected after the PRV, and its sensor pads should be replaced every 12 months or after a leak. These are essential additions to any pressurized water filtration setup
