Leakage test: Legally compliant testing of your private wastewater pipe according to DIN 1986-30

Are your private wastewater pipes on your property leak-proof? As a property owner in North Rhine-Westphalia, you are legally obligated to have them checked regularly. Blix Drain Cleaning from Bad Honnef performs the official leak test (leakage test according to DIN 1986-30) for your wastewater pipes professionally and reliably – in Bonn, Siegburg, Königswinter, Hennef, Asbach, Neustadt (Wied), and throughout the Rhein-Sieg district and Westerwald region.

Leaky sewage pipes pose a threat to the environment and public health. They can:

• Contaminate groundwater (leaking wastewater).
• Contaminate the soil.
• Allowing foreign water to enter the sewer system (groundwater can enter the pipe system through leaks and burden the sewage treatment plants).

To prevent this, the state water legislation of North Rhine-Westphalia mandates the regular inspection of private wastewater pipes.

We conduct the inspection in accordance with all legal requirements and using state-of-the-art technology:

First, we thoroughly clean the pipe to be tested in order to obtain a clear picture of the inner pipe walls and to remove blockages that could distort the result.

Using a high-resolution pipe camera, we inspect the pipe section by section. This allows us to visually assess the condition of the pipe and document it on a monitor. We can see:

• Cracks and fractures
• Leaky joints
• Root growth
• Deposits and deformations

For some types of pipes (e.g., pressure pipes) or for precise leak testing, a pressure test is also used. In this test, the pipe is pressurized with air or water. A drop in pressure indicates whether and where the pipe is leaking.

You will receive a complete test report from us, including a video of the camera inspection. This official document proves the tightness of your pipes and serves as proof for the relevant authority (e.g., the municipality or water supplier).
