The B-inspection

As the owner of a water tank, it is important to ensure that it is in good condition and safe to use. A  B-inspection helps you to identify and resolve any issues with your water tank in a timely manner.

What does the B inspection entail?

A B-inspection, as described, is a visual inspection of the water tank that occurs every 5 years. During this inspection, the condition of the tank and its components is assessed. The inspection includes an evaluation of the general state of the tank, the presence of rust, the condition of the coating, the existence of cracks or dents, and other factors that can affect the safety and durability of the tank. A detailed list of the inspection points can be found in Technical Bulletin 67b.

The B-inspection, following the annual A-inspection (which is a visual examination of the exterior of the water tank), involves reviewing the reports from the A-inspection and any corrective measures taken. During the B-inspection, there is also a visual inspection of the inside of the water tank. This internal inspection is conducted using a dive inspection method.

In addition, the accessories of the water tank are inspected, including the pipes, valves, and pumps. During this inspection, attention is paid to leaks, the overall condition of these components, and whether they are functioning correctly. An inspector will also verify if the water tank has been installed correctly and if its location is safe.

After the inspection is completed, you will receive a report containing the findings of the inspector. If any issues are identified during the inspection, the inspector will provide recommendations regarding any necessary repairs or replacement of components. This allows you to ensure that your water tank remains safe and reliable.
