Product Information
Full details
The Plumbright Single Check Valve (SGV15DZR) is an essential component for professional plumbers and DIY enthusiasts seeking reliable backflow prevention in 15mm plumbing systems. Engineered from high-quality DZR brass, this valve provides excellent corrosion resistance and long-term durability for various water applications, though it is specifically intended for single-direction flow control rather than pressure regulation.

FAQs
What is DZR brass?
DZR stands for Dezincification Resistant. It is a type of brass alloy designed to resist corrosion in environments where standard brass might degrade, ensuring a longer lifespan.
Can I use this valve on heating systems?
Yes, it is suitable for various water applications, including heating systems, provided the diameter is 15mm and pressure requirements are within spec.
Does it matter which way the valve is installed?
Yes. There is a flow arrow on the valve body that must point in the direction of the water flow for the valve to function correctly.
Is this a double check valve?
No, this is a single check valve designed for simple backflow prevention.
Can I install this vertically?
The valve can be installed in vertical or horizontal positions as long as the flow direction matches the arrow indicator.
Does it require specific maintenance?
While the DZR material is durable, we recommend inspecting it periodically for sediment buildup that could impede the internal mechanism.
Troubleshooting
Water flow is blocked completely
Verify the valve is installed in the correct flow direction. Ensure the flow arrow points away from the supply.
Backflow is still occurring
Check the valve for internal debris that may be preventing the seat from closing fully. Flush the line to clear obstructions.
Minor leakage at the connection points
Check that the compression nuts are properly tightened and that pipe inserts are used if required for PEX or plastic piping.
Pros and Cons
Pros
- High resistance to corrosion due to DZR brass material
- Reliable backflow prevention performance
- Standardized 15mm sizing for wide compatibility
- Durable build quality for long-term reliability
Cons
- Limited to 15mm pipe diameters only
- Requires proper orientation during installation to function
- Not intended for use as a flow-regulating or isolation valve
Setup, Compatibility & Care
To install the valve, ensure the arrow indicating the flow direction is pointed toward the desired output. Always verify that the pipe ends are clean, free of burrs, and properly cut to 15mm. Because this is a mechanical component, ensure it is installed in an accessible location for future inspection. Avoid overtightening fittings, as this can stress the DZR brass. While the material is highly resistant to dezincification, keeping the system free of excessive sediment will prolong the life of the internal seating mechanism. Regular annual checks are recommended to ensure the valve has not become seized due to calcium or debris buildup.
