Reduced Pressure Zone (RPZ)

Our RPZ valve servicing programmes ensure backflow prevention devices remain compliant, reliable, and fully operational which prevents contamination, and protects the safety of building users and the wider water supply.

Regular testing and servicing of RPZ valves is a critical control measure in protecting potable water, particularly in environments where there is an increased risk of backflow and system pressure changes.

A structured RPZ maintenance programme goes beyond meeting regulatory requirements. It provides confidence that valves are working as intended, supports ongoing compliance, and helps estates teams avoid reactive issues by identifying problems early.

What’s Included with RPZ Valve Servicing

Inspection and testing of RPZ valves
Measurement of pressure and performance against required standards
Identification of faults, wear, or performance issues
Servicing and certification in line with current regulations
Clear reporting and records for compliance and audit purposes

RPZ valves are often installed in higher-risk environments and play a critical role in safeguarding public health. However, they are frequently overlooked once in place. Without regular testing and servicing, faults can develop unnoticed, leaving systems exposed.

We support clients across healthcare, commercial, and other high-risk settings, working closely with estates and facilities teams to ensure RPZ servicing aligns with wider water safety responsibilities. Where required, we integrate RPZ servicing into broader maintenance and compliance programmes to provide a joined-up approach.

All RPZ valve servicing is carried out in line with relevant British Standards and best practice, ensuring work is completed safely, correctly, and with minimal disruption to your site.

If you’re unsure how many RPZ valves you have on site, when they were last tested, or what’s required to remain compliant, our team can help. We provide clear guidance, practical support, and a reliable service that takes the uncertainty out of RPZ valve management and helps you stay in control of your water systems.
