Hydrostatic Pressure Testing Services UK
Hydrostatic pressure testing is the industry-standard method for verifying that newly installed, repaired, or existing pipelines can safely withstand their operational pressures. It is a non-negotiable process for ensuring the structural integrity and leak-tightness of your assets, which is essential for safety, efficiency, and regulatory compliance.
At Pipe Testing Services (PTS), we provide expert hydrostatic pressure testing services across the UK. We use industry-leading methods and comprehensive data logging to deliver reliable, certified results for clients nationwide, from new water main commissions to existing infrastructure assessments.
The Hydrostatic Pressure Testing Process Explained
At PTS, we adhere to rigorous procedures, often following the WRc Type 2 method and specific Water Authority specifications, to ensure accurate and compliant testing. Our typical process includes:
- Planning & Preparation: We start with a detailed review of the pipeline system, specifications (like BS EN 805 or client requirements), and site conditions to develop a tailored test plan, including safety protocols and water management strategies.
- Isolation & Filling: The specific section of pipeline to be tested is safely isolated using appropriate end caps, flanges, or valves. The section is then carefully filled with water, ensuring all air is purged from the system, which is critical for accurate results.
- Pressurisation: Using calibrated pumps and gauges, the water pressure inside the pipeline is gradually increased in controlled stages up to the specified test pressure (often 1.5 times the maximum operating pressure).
- Stabilisation & Test Hold: The test pressure is held for a pre-determined period (as per specification) allowing the system to stabilise. During this hold period, pressure is continuously monitored.
- Data Logging & Monitoring: Throughout the pressurisation and hold phases, we utilise precise, calibrated data loggers to continuously record pressure readings. Our technicians also conduct visual inspections for any signs of leakage at joints, fittings, or along the pipe length.
- Depressurisation & Water Management: Once the test duration is complete and results are satisfactory, the pipeline is safely depressurised in a controlled manner. PTS manages the test water responsibly, often incorporating dechlorination if required, to ensure environmentally safe discharge according to regulations.
- Reporting: We provide a comprehensive test report detailing the methodology, test parameters, pressure logs, observations, and a clear pass/fail result, confirming compliance with the required standards.
The PTS Hydrostatic
Testing Process
PTS provides hydrostatic testing services for a wide range of critical applications:
- New Water Mains & Distribution Networks: Verifying the integrity of newly installed pipelines (PE, ductile iron, steel etc.) before they are commissioned and put into service, essential for adoption by Water Authorities.
- Repaired Pipeline Sections: Ensuring that repairs or modifications have restored the pipeline’s structural soundness and leak tightness.
- Industrial Pipework: Testing process pipelines within industrial facilities to ensure safety and operational reliability.
- Rising Mains: Confirming the integrity of crucial rising mains connecting pumping stations to distribution networks.
- Gas Pipelines (Stage 1): While pneumatic testing is standard for gas lines, hydrostatic testing is sometimes required for initial strength proving (Stage 1) of high-pressure gas pipelines, particularly large diameter sections. PTS has the capability to manage water delivery, testing, dewatering, and drying for these specific scenarios.
Benefits of Hydrostatic Testing with PTS
Conducting hydrostatic testing with PTS provides significant advantages for ensuring pipeline integrity and compliance. Our meticulous approach, using methods like WRc Type 2 and adhering strictly to Water Authority specifications and standards like BS EN 805, guarantees regulatory compliance and provides auditable proof that your pipeline meets required performance criteria. This rigorous testing is fundamental for safeguarding public health by ensuring the pipeline is leak-free, preventing potential contamination of potable water supplies.
Identifying weaknesses or leaks under controlled test conditions prevents unexpected failures once the pipeline is operational, avoiding costly emergency repairs, service disruptions, and potential environmental damage. Our comprehensive data logging provides not just a pass/fail result, but valuable insights into the pipeline’s performance under pressure, contributing to better long-term asset management decisions. Choosing PTS delivers peace of mind through proven expertise and reliable results.

Hydrostatic Testing FAQs
Hydrostatic testing uses water, which is incompressible. This makes pressure drops from leaks easier to detect and means the energy released during a failure is significantly lower, making it inherently safer than testing with compressed gas.
A proof test is typically performed on a brand new system to verify its strength and confirm it has been manufactured and installed correctly. A leak test is more often performed on an existing system to detect any leaks that may have developed over time.
A failure indicates a leak or structural flaw. Our team will help you identify the location of the failure so that a targeted repair can be made. The system must then be re-tested.
Yes, we manage the entire process, including the sourcing of water for filling and the safe, compliant management and disposal of the test water afterwards.
