Hydrostatic Pressure Testing Services UK | Pipe Testing Services
Ensuring the structural integrity and leak-tightness of pipelines is non-negotiable for safety, efficiency, and regulatory compliance.
Hydrostatic pressure testing is the industry-standard method for verifying that newly installed, repaired, or existing pipelines can safely withstand operational pressures. At Pipe Testing Services (PTS), we provide expert hydrostatic pressure testing services across the UK, utilising industry-leading methodologies and comprehensive data logging to deliver reliable results for clients nationwide.
Whether commissioning new water mains, verifying repairs, or assessing existing infrastructure, our tailored hydrostatic testing solutions provide the assurance you need.
Hydrostatic testing is a controlled process used to evaluate the strength and identify potential leaks in pipelines, pressure vessels, and other components designed to hold pressure. It involves filling the isolated test section completely with a liquid, typically water, and pressurising the system to a level significantly higher than its normal operating pressure.
This test pressure is held for a specific duration while technicians meticulously monitor for any pressure loss, visible leaks, or signs of deformation. It’s a definitive way to confirm structural soundness and ensure the system is fit for service.
The PTS Hydrostatic Testing Process
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, the intended medium, providing a realistic assessment of performance under operational stress. Water is incompressible, making pressure drops due to leaks more readily detectable, and the energy released during a failure is significantly lower than with compressed gas, making it inherently safer for high-pressure tests on liquid systems.
PTS conducts hydrostatic testing in accordance with relevant UK and industry standards, including BS EN 805, IGN 4-01-03, WRc Type 2 methodology, and specific incumbent water authority specifications as required by the project.
The duration depends on the pipeline length, volume, test pressure, required hold time (often 1-2 hours or more as per specification), and stabilisation period. Preparation and depressurisation also add time. We plan efficiently to minimise overall duration.
If the pressure drops below acceptable limits or leaks are observed, the test is failed. PTS will document the findings to help locate the failure point. Repairs must be completed before the section can be re-tested successfully.
Yes, PTS can manage the entire process, including sourcing and transporting water (if needed, e.g., via tanker), filling the pipeline, conducting the test, and managing the safe and environmentally compliant depressurisation and discharge, including dechlorination services
