This consultation closed on 3 October 2022. We received 42 responses to the consultation.

We analysed the responses and made more amendments to our proposed specifications. We then notified the World Trade Organisation (WTO) of a potential technical barrier to trade and the European Union. This is required under the Northern Ireland Protocol because these changes are relevant to compliance in Northern Ireland.

We received no comments from these notifications. The summary of responses and the government response to them, along with the final regulator specifications and test code sheets, are expected to be published in autumn 2023.

Consultation description

We want to know what you think about Defras proposed changes to 11 specifications made under the Water Supply (Water Fittings) Regulations 1999.

These regulations are needed to protect human health from contaminated drinking water. We need to update the specifications to reflect modern toilet designs.

One change will introduce a new backflow prevention arrangement in the toilet cistern. Another will introduce a new test to ensure that water from the toilet pan cannot contaminate the water in the cistern.

The other changes will make the rules consistent and clearer and focus on how a product must perform.

We also want to gather evidence on faulty toilet valves that cause a loss of water and look at what could be done to improve these products.
