WRAS Approved Pumps and Valves

Why are WRAS approved pumps and valves important?

Here at T-T we are continually striving to meet the highest standards with a range of WRAS approved pumps and valves to suit clean water applications.

When installing a product which will transfer or receive water from the public mains water supply in the UK, it is a criminal offense if it does not comply with the Water Supply (Water Fittings) Regulations or Scottish Byelaws.  Both of these bodies ensure that water fittings do not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard’.

There are two types of WRAS approval that products can comply with. These are full product WRAS approvals or WRAS approved materials. Having WRAS approved materials demonstrates that elements within the product are compliant with WRAS regulations and does not affect the quality of water, for example, O-rings. Whereas, product WRAS approval shows that the entire product has undergone testing and is fully WRAS approved.

WRAS approved pumps and valves show that our products are compliant with water regulations and meet the standards required when transferring clean water. Having WRAS approval is the best way to demonstrate compliance as it is granted directly by representatives of the water suppliers and is therefore recognised by every water supplier in the UK.

WRAS Approved Valves

To achieve this accreditation, our valves have undergone a stringent third-party evaluation process encompassing mechanical assessments and material examinations to demonstrate that the valves are not detrimental to water quality.
