Primaflow Vcd Double Check Valve - 15mm - WRAS Approved

WRAS approval signifies that the product has been tested and certified by the Water Regulations Advisory Scheme, confirming it meets the stringent water supply (water fittings) regulations in the UK, ensuring it is safe for use with drinking water and does not pose a risk to health.

Backflow prevention is a mechanism designed to stop water from flowing backward in a plumbing system. This is important to prevent potentially contaminated water from mixing with the clean, potable water supply.

While designed for general water systems, the product information does not specify suitability for high-temperature hot water. It is primarily intended for potable cold water applications unless otherwise stated by the manufacturer for specific models.

You typically need a double check valve if there's a risk of backflow from a non-potable source (like a garden hose or a boiler) into your main water supply. Local regulations often mandate their use in certain installations.

Product information provided does not include warranty details. Please refer to the retailer or manufacturer's official documentation for specific warranty terms.

The dimensions are approximately 78mm in length, 26mm in width, and 26mm in height.

Ensure the valve is correctly tightened onto the pipe. Check that the pipe ends are clean and undamaged. Re-seal fittings if necessary, following standard plumbing practices.

Verify the flow direction arrow on the valve is pointing correctly. Check for any obstructions in the pipework before or after the valve. If the valve is internally faulty, it may require replacement.

Confirm the water supply is on and the valve is installed in the correct flow direction. Check for blockages. If the valve is stuck shut, it may need to be replaced.
