Product Information
Full details
The Plumbright Double Check Valve (15mm) is an essential component for residential and commercial property owners and professional plumbers seeking to maintain high water quality standards. Its primary benefit is the reliable prevention of backflow, ensuring that water cannot reverse its direction and contaminate the clean water supply. While it offers robust protection against fluid reversal, users should note that this valve requires professional installation and proper orientation to function effectively within a pressurized plumbing system.

FAQs
Can I install this valve horizontally and vertically?
Yes, this valve can typically be installed in both horizontal and vertical positions, provided the directional arrow matches the water flow.
Does this valve require regular maintenance?
It is a low-maintenance device, but it should be visually inspected during annual plumbing checks for any signs of corrosion or leakage.
Is this valve suitable for hot water systems?
Yes, it is designed to handle standard domestic water temperatures, but you should verify it stays within the product's rated temperature range.
How do I know if the valve is faulty?
If water flow is restricted or if there is evidence of backflow occurring in the system, the internal mechanism may be obstructed or worn.
Does this valve replace a stopcock?
No, this is a check valve, not a shut-off valve. It prevents reverse flow but cannot be used to isolate the water supply.
Troubleshooting
Water is not flowing through the valve
Verify that the valve is installed in the correct orientation. Ensure the flow arrow is pointing in the direction of the water movement.
Valve is making a vibrating or 'chattering' noise
This often indicates air in the lines or high water pressure. Bleed the air from the system or install a pressure-reducing valve if necessary.
Visible leaking at the connection points
Ensure that the connections are tightened correctly and that the appropriate sealant or PTFE tape was used during the initial installation.

Setup, Compatibility & Care
For optimal performance, ensure the valve is installed by a qualified plumber. The valve body is marked with a directional arrow; this arrow must point in the direction of the water flow. Before installation, ensure the pipes are free of debris to prevent the internal check mechanism from jamming. Compatibility is guaranteed for standard 15mm diameter plumbing pipes. For maintenance, periodically check the valve for any signs of leaks or abnormal pressure drops, and ensure the surrounding pipework is secure. If the system experiences a prolonged shutdown, have the valve inspected to ensure the spring-loaded mechanism remains free to move.
