FAQs
What is DZR brass?
DZR stands for Dezincification Resistant. It is a specific type of brass alloy designed to resist corrosion in environments where standard brass might suffer from zinc leaching.
Can I install this horizontally and vertically?
Yes, provided the flow direction arrow aligns with the water supply path, the valve can be installed in either orientation.
Is this valve lead-free?
The Plumbright DZR valve is manufactured to meet industry standards for water safety; please check the specific compliance rating on the packaging for your region.
How do I know if the valve is failing?
If you notice a drop in pressure or unusual noises at a fixture, or if a backflow test fails, the internal check mechanism may be obstructed or worn.
Does this valve require maintenance?
It is generally maintenance-free, though visual inspections during routine home plumbing checks are recommended.
Troubleshooting
Water flow is significantly restricted
Check that the valve was installed in the correct direction; an arrow on the valve body indicates the flow path.
Valve is leaking from the connection point
Ensure that the threads are properly sealed with plumbing tape and the fitting is tightened sufficiently.
Clattering or vibration noise in the pipe
This may indicate air trapped in the system or fluctuating pressure; bleed the air from your lines and check the water pressure regulator.

Setup, Compatibility & Care
Installation of the 15mm valve should be carried out in accordance with local water regulations. The valve must be installed with the flow direction arrow facing the direction of water usage. Ensure all connections are tightened appropriately to avoid leaks, using thread seal tape or compound where necessary. For care, period checks should be performed during routine plumbing maintenance to ensure the valve has not become seized or obstructed by mineral deposits, particularly in hard water areas. No internal lubrication is required, but ensuring the water supply is flushed before final tightening prevents debris from damaging the check mechanism.
