Use the search facility to find an RPZ valve tester in your area.
What are RPZs?
Type BA backflow protection devices are more commonly known as Reduced Pressure Zone valves or RPZ valves. It is a legal requirement to have these devices checked on a regular basis, at least yearly, to ensure they provide the backflow protection required.
All installations, commissioning and testing must be carried out in accordance with the Water Suppliers' Approved Installation Method AIM-08-01. The commissioning and testing of these valves must only be carried out by an accredited tester approved by the local water supplier.
How can I become an RPZ tester and be listed on the WRAS website?
If you would like your details to be added to the RPZ testers listed on the WRAS website, you need to successfully complete an RPZ course that has been endorsed by WRAS.
Currently only one course has been recognised which is run by Develop Training Limited.
Candidates have an opportunity to elect to be publicly listed on the WRAS website when they fill in the application form for the Develop training course. Once candidates have successfully completed a course, Develop Training Limited sends WRAS a list of successful candidates who wish to be listed on the WRAS website. WRAS then adds these to the WRAS website.
Please note that the RPZ Water Suppliers' Approved Installation Method AIM-08-01 is under review, so this process is likely to change, following consultation.
One of the services currently provided by WRAS is the hosing of a list of RPZ testers. Upon publication of a revised AIM-08-01 mentioned above, there will be changes to the search facility of RPZ testers and how they are listed. WRAS reserves the right to amend or remove details from the listing. WRAS will endeavour to contact companies prior to making any changes, in some situations WRAS may do so without prior notice.
Information for RPZ testers
As part of the AIM 08-01 review, WRAS recently updated the list of RPZ testers published in the search facility with the aim to improve the availability of those testers who currently provide RPZ testing services. If, as an RPZ tester, you no longer appear on this list and wish to do so, please send updated details using the form below. Email completed forms to firstname.lastname@example.org or post them to us.
The course certificate states that this is only valid for three years - are RPZ testers removed from the website after three years?
The water industry has agreed that no time limit should be placed on the listings on the WRAS website. However RPZ testers are expected to maintain their competence, by frequently carrying out RPZ tests.
