What Are WRAS Approved Taps and Showers?

WRAS stands for Water Regulations Advisory Scheme, a UK regulatory body that ensures that plumbing fixtures and appliances comply with water supply regulations. Taps and showers that have been awarded this mark show that they have been tested and approved by WRAS to meet the necessary standards of safety and water efficiency.

The following are some of the key features of WRAS approved taps and showers.

  • Compliance with water regulations: WRAS approved taps and showers are designed and manufactured to comply with the UK’s water supply regulations. This ensures that they do not contaminate or waste water and meet the required safety standards.
  • Backflow prevention: Effective backflow prevention means they prevent water from flowing back into the mains supply system. This is vital to prevent contamination of the public water supply.
  • Durability: WRAS approved taps and showers are durable and built to withstand the rigors of regular use.
  • Water conservation: Helps to conserve water and reduce water bills. Features such as flow restrictors or aerators are often included to avoid wasting water without sacrificing the experience.
  • Testing and certification: In order to be recognized by WRAS, taps and showers undergo rigorous testing and manufacturers must provide detailed documentation and evidence of compliance.
  • Legal Requirements: In the UK, it is a legal requirement that certain types of plumbing fixtures, including taps and showers, are approved by WRAS before they are installed in buildings connected to the public water supply.

The Importance of WRAS Approved

The importance of WRAS (Water Regulations Advisory Scheme) accreditation for plumbing fixtures and fittings in the UK cannot be overemphasized, and here are a few of the main reasons for its importance.

  • Ensuring compliance with water regulations: WRAS approved ensures that plumbing fittings such as taps and showers comply with the UK’s stringent water supply regulations, preventing contamination of public water supplies and maintaining healthy water quality.
  • Protecting public health: One of the key criteria for WRAS approved taps is the prevention of backflow, which is vital for protecting public health. Preventing backflow ensures that water flows in one direction only, preventing potentially contaminated water from entering the main supply system and avoiding some of the diseases that can be spread through water.
  • Prevent water waste: WRAS approved taps and showers meet water conservation codes. With built-in throttles, aerators, etc., they reduce water consumption without sacrificing the experience of using them.
  • Quality Assurance: WRAS accreditation involves rigorous testing and assessment of plumbing fixtures. When applying for WRAS accreditation, manufacturers must provide documentation or evidence of compliance with accreditation standards to ensure that the product meets quality and safety standards.
  • Legal Requirements: In the UK, it is illegal to install plumbing fixtures without WRAS approved, the homeowners, installers, or manufacturers are required to comply with these regulations, or else can result in fines and penalties.
  • Consumer Confidence: When consumers see the WRAS approved mark on plumbing products, they can be confident that these products have been thoroughly evaluated and are safe for use in homes and commercial buildings.
  • Longevity and Reliability: WRAS approved taps are durable and corrosion-resistant, ensuring a longer lifespan and reducing the frequency of replacement.
  • Professional requirements: Plumbers and installers often prefer to use WRAS approved products because they offer standardized installation specifications and fittings, as well as fewer after-sales issues!

  • Mechanical and automatic valves: refers to valves used in water supply systems, which are usually mechanical or automatic and are used to control the flow of water, e.g. pressure reducing valves, check valves and pressure reducing valves.
  • Materials and Substances: refers to materials and substances involved in contact with and potentially contaminating water, including items such as piping, fittings, and seals, ensuring that they are made of safe, non-toxic materials.
  • Backflow prevention devices and fluid categories: Backflow prevention devices are essential to prevent water and contaminants from backing up into the main supply system.
  • Piping System Specification and Installation: This category focuses on the specification and installation of piping systems. It provides guidelines and standards to ensure that piping systems are designed and constructed in compliance with water regulations, including proper sizing and installation methods.

How Do Taps or Showers Become WRAS-Approved?

Taps (faucets) or Showers can be approved by wras through rigorous testing and approved processes to ensure they comply with UK water supply regulations and safety standards. Below is an overview of how taps and showers gain WRAS approval:

  • Manufacturer Submission: The process begins when the manufacturer or distributor of the tap submits the product for WRAS approval, providing detailed information about the design, materials and specifications of the tap.
  • Product Assessment: WRAS assessors review the submission to ensure that the design and materials of the tap comply with the relevant water supply regulations, verifying that the tap is made from safe, non-toxic materials and is suitable for contact with drinking water.
  • Testing and Performance Evaluation: This testing includes evaluating factors such as flow rate, pressure, effectiveness in preventing backflow, and temperature control.
  • Material Compatibility: Materials used in taps or showers, including seals and gaskets, are evaluated for their compatibility with drinking water and their resistance to corrosion and degradation over time.
  • Durability: They are tested for longevity to ensure they can withstand the rigors of regular use.
  • Water Use Efficiency: Evaluate their water flow and water conservation performance, such as flow restrictors or aerators.
  • Quality Assurance: Manufacturers’ manufacturing processes and quality control procedures are also scrutinized to ensure consistent quality and safety of wras-approved products.
  • Documentation Verification: Comprehensive documentation and evidence of compliance must be provided throughout the testing and assessment process.
  • Certification is awarded: WRAS approved is awarded if the tap passes all necessary tests and meets WRAS requirements. The certification is usually valid for a specific time, after which it may need to be reassessed to maintain its approval.
  • Use of the WRAS Mark: Once WRAS approval has been granted, the tap can display the WRAS approved mark. This mark is a clear indication to consumers, plumbers, and installers that the tap complies with the relevant water supply regulations and is safe to use for drinking water.

It is important to note that WRAS approval is specific to individual tap models or product variants. Therefore, if a manufacturer offers a number of different product designs, then each design may need to be re-approved
