Key Features & Benefits

✔ WRAS Approved for Potable Water

This valve complies with WRAS standards, making it safe for use in systems that supply drinking water. It protects water quality by preventing contamination from backflow or back siphonage.

✔ Durable DZR Brass Construction

Manufactured from high-quality DZR brass, this check valve resists corrosion and dezincification, particularly in aggressive or hard water areas. This ensures long-term reliability even in demanding plumbing environments.

✔ Compression Fit for Easy Installation

The 15mm compression ends allow for fast, tool-assisted installation with copper pipes or suitable plastic systems using appropriate inserts. Ideal for both new installations and retrofit work.

✔ One-Way Flow Control

The internal check mechanism opens under forward flow and automatically closes when the flow reverses, ensuring unidirectional movement of water to maintain hygiene and safety standards.

✔ Compact and Efficient Design

Its small profile allows it to fit easily into confined spaces behind units or within service voids, while still offering full-flow performance with minimal pressure drop.

Typical Applications

• Domestic and commercial cold water supply lines

• Appliance connections (e.g., washing machines, dishwashers)

• Water storage tanks and header tanks

• Boiler feed systems

• Isolation and safety valves in pressurized systems

• General plumbing systems where backflow prevention is required

Installation Guidelines

1. Pipe Preparation: Ensure pipes are clean and cut square. Remove burrs to avoid damage to the olive.

2. Apply Compression Nuts: Slide the compression nut and olive onto the pipe.

3. Insert Valve: Push the pipe fully into the valve ends, ensuring a proper seal against the internal stop.

4. Tighten Joints: Use suitable spanners to tighten the compression nuts. Do not overtighten to avoid damaging the valve body.

5. Check Flow Direction: An arrow on the valve body indicates the correct direction of flow. Install accordingly.

6. Test System: Once installed, test the system for leaks and confirm the valve functions as expected.

Note: Always install in accordance with local plumbing regulations and ensure compatibility with system materials.

Maintenance Recommendations

• Routine Inspection: Check valve operation periodically during annual system maintenance.

• Flush Systems Before Installation: Always flush the pipe system before installing to prevent debris from damaging the internal mechanism.

• Do Not Attempt to Dismantle: The valve is not serviceable. If malfunction occurs, replace the unit.

Frequently Asked Questions (FAQs)

Q: Can this check valve be installed in any orientation?
It is recommended to install the valve horizontally with the flow arrow in the correct direction to ensure optimal performance. Vertical installation is possible but should be verified based on system pressure and flow rate.

Q: Is this suitable for central heating systems?
Yes. While it is primarily intended for potable water, it may be used in certain closed-loop heating systems to prevent unwanted flow reversal, provided system compatibility is confirmed.

Q: How does DZR brass improve performance?
DZR brass is specifically designed to resist dezincification—a form of corrosion that can weaken standard brass fittings when exposed to aggressive water. This makes it ideal for long-term durability in UK plumbing systems.

Q: Can this be used with plastic pipe?
Yes, if the plastic pipe is compatible with compression fittings and suitable pipe inserts are used. Always check with the pipe manufacturer’s guidelines.
