Water Product Certification - Case Studies

RAH Consultancy undertook a project to oversee the testing to the requirements of the Water Regulations and the anti-scald measures of the TMV3 Scheme for Crosswater. Like many organisations the specialised knowledge of the testing requirements of these schemes and the necessary knowledge of materials of construction requires time and experience to be quick and successful and this RAH Consultancy can supply

Following the success of this minor project RAH Consultancy was retained on a yearly basis to develop a major project for Crosswater who wished to offer complete ranges of products that were WRAS Approved.

The project entailed:

• A detailed study of each complete model

• A detailed study of the drawings

• A detailed study of the materials of construction

• The provision of advice to the manufacturer of each model as to changes to the manufacture process.

• The provision of advice as to the selection of materials of construction that met the requirements of the Water Regulations

• The completion of all the application forms for each model and liaison with the testhouse during testing.

• In the event of failure of a device the provision of remedial actions so as to ensure future success.

During the four years over which the project ran RAH Consultancy completed over two hundred applications for Crosswater products.

RAH Consultancy also acted as the companies Technical Manager and on their behalf attended the technical Meetings of the Bathroom Manufacturers Association and Buildcert reported on any technical issues to the company.

We worked with Crosswater on the completion of all the requirements of the Construction Products Regulations as these came into force and successfully completed their changover on time and to the requirements of the Regulations.

Our association continued until Crosswater’s internally recruited staff were sufficiently advanced to take over the role.

RAH Consultancy has now been retained by the Swedish manufacturer FM Mattsson to prepare their products for UK Water Regulations Approval and Buildcert Certification.

Acting as their technical expert in this field the works include the following:

We are, in particular, working with them and giving advice on the materials testing of items such as Shower Hoses, this is ensuring that the duty of care of a Manufacturer to Legionella control issues are successfully met and appropriate to the risk.

We advised Crown Water Heaters on the requirements for the Water Regulations with regard to their wall mounted water heaters.

The project was mainly notable for the work required to ensure the material of the internal enamel lining was acceptable to the Water Regulations. Our advice ultimately resulted in this material passing the test and acceptance criteria of the Water Regulations.

Approval of a range of expansion joints for use in Water Supply Systems.

These joints were tested and accepted by the Water Requlators as meeting the requirements of the Water Regulations.

RAH Consultancy is pleased to collaborate on any size of project to ensure a product is capable of meeting the Water Regulations.

After being approached by HSL Compliance, a large water condition monitoring organisation, RAH Consultancy was asked to design a syllabus for them which would include current Water Regulations and also the installation, commissioning and testing of Thermostatic Mixing Valves (TMV's) so as to meet the requirements of TMV2 and TMV3.

The work included the provision of all course notes and examination papers for the in-house City and Guilds course. On completion of the design stage we acted as the course lecturer for the organisation, this included conducting the practical element of the installation and maintenance module as well as the theoretical modules.

On completion of the syllabus the company found that their employees had increased confidence and greater competence in the undertaking of their duties.
