If you are responsible for an RPZ valve or an RPZ tester, do you know about the new requirements that come into force in 2026?

What’s changing?

There are going to be two significant changes in 2026

1. From the 1^st July equipment used to test RPZ valves must conform with a new minimum specification

2. RPZ testers must now periodically revalidate their qualification 

How will this affect you?

If you are an RPZ tester you need to:

• Ensure your test gauge is compliant before the July deadline

• Provide your scheme, if you belong to one, with details of any new test equipment. They should also be able to assist with any questions

• If you are recognised on a localised basis talk to your water undertaker, they are likely to suggest you join a scheme

• Sign up for alerts from Water Regs UK so you know when the training, to revalidate your competency status, goes live

If you are responsible for RPZ valves you need to:

• Confirm before the deadline the RPZ tester you use has the right equipment and can test your valve(s) – there are different types.

• Before the end of 2026 RPZ testers will have to renew their qualification for your test certification to be accepted.

• If you want to make sure your tester’s qualifications are up to date, use the RPZ valve tester search on the WaterSafe website.  This only list those with valid qualifications and until July will identify if they haven’t confirmed their equipment is compliant. 

• Sign up for alerts from Water Regs UK so you know about changes affecting you.

Where can you find more information ?

Water Regs UK not only publishes the RPZ AIM and accompanying minimum specification but lots of other RPZ related information including a series of RPZ FAQs and a list of UKAS accredited calibration services
