London Drainage Services (LDS) offers drain smoke testing to assess the integrity of pipework and drainage systems, helping to identify defects, trace odours, and ensure safety. By introducing non-toxic smoke under pressure into the drainage system, this testing method allows our engineers to detect any leaks or defects, as the smoke will escape wherever there is a flaw, both above and below ground.
Drain smoke testing is also highly effective in pinpointing rodent entry points, evaluating vent pipe performance, and locating hidden manholes and inspection chambers. If smoke passes through certain areas, it may indicate a risk of sewer gases entering the property, highlighting the importance of a properly sealed drainage system. This non-invasive, cost-effective testing provides clear results while ensuring safety for everyone on-site.
LDS provides reliable, efficient smoke testing for drainage assessments. Here’s why our service is trusted.
Our drain smoke testing services offer a reliable way to detect leaks, cracks, and hidden faults within your drainage installation. This non-invasive testing method uses harmless, pressurised smoke to identify potential issues in the system without requiring excavation or major disruption. We begin by sealing off sections of the drainage system, then introduce the smoke under controlled pressure to fill the pipes and detect any escape points.
The smoke will visibly exit through cracks, misalignments, or leaks in the drainage system, allowing our team to pinpoint exact areas that require attention. This method is especially useful for identifying leaks that may not be visible through CCTV surveys, ensuring a thorough inspection of the entire drainage installation.
Once the test is complete, we assess the results and provide you with a clear report on the condition of your drainage system. If any faults are found, we can recommend appropriate repair solutions to restore the integrity of your system. Our drain smoke testing is ideal for both residential and commercial properties, offering an efficient, safe, and cost-effective approach to maintaining optimal drainage function. This proactive testing service helps prevent future issues, ensuring your drainage installation remains in top condition.
