💧 What is WRAS?
WRAS (Water Regulations Advisory Scheme) is a UK certification that ensures plumbing products and materials meet the Water Supply (Water Fittings) Regulations. These regulations are designed to prevent water contamination, promote efficient use, and ensure safe installation practices.
If a product is WRAS approved, it means it has been tested and certified as safe for use with drinking water and is compliant with UK regulations.
🧪 WRAS Testing & Certification Process
To gain WRAS approval, a product or material must pass two critical tests:
1. Mechanical & Performance Testing
This checks that the product performs reliably and won’t fail under pressure or temperature changes. It includes tests like:
Pressure and leak resistance
Strength and durability
Valve operation and shut-off functionality
2. Non-Metallic Material Testing
For components that come into contact with drinking water (like seals, seats, and coatings), testing ensures they don’t leach harmful substances, affect taste or odour, or promote bacteria growth.
This part is done in accordance with BS6920 standards.
Once both tests are passed, the product receives a WRAS Certificate and can be listed in the WRAS Approved Product Directory.
📜 How Long Does WRAS Certification Last?
WRAS approval is valid for five years, after which the product must be re-tested to ensure continued compliance. During this time, manufacturers must also ensure there are no material or manufacturing changes that could impact performance or water safety.
🧠 WRAS FAQs
❓Do all plumbing products need WRAS approval?
Not legally, but any product connected to the mains water supply must comply with the Water Fittings Regulations. WRAS approval is a trusted way to demonstrate that compliance.
❓Can I install non-WRAS products in domestic settings?
It’s risky. If an inspector finds unapproved components in your system, you may need to replace them to meet regulations. WRAS approved products simplify inspections and approvals.
❓Is WRAS approval the same as CE or UKCA marking?
No — CE and UKCA cover general product safety and manufacturing standards. WRAS specifically deals with water system compliance and hygiene.
