What is the purpose of anchor blocks installed on a drain?

The installation of anchor blocks on a drain serves primarily to prevent movement or displacement of the drain. These blocks are crucial in securing the drainage system in place, ensuring that it remains stable despite surrounding soil conditions, changes in temperature, or the pressure from water flow. By anchoring the drain, the system can maintain its intended alignment and function over time, which is vital for preventing backflow and blockages.

While supporting the weight of the drain is an important consideration, it is not the primary function of anchor blocks; drains are typically designed to handle their own weight through proper grading and installation practices. Ensuring proper flow direction is managed through the design of the drain itself and its gradient, rather than the use of anchor blocks. Enhancing aesthetic appeal is not a function of anchor blocks, as they are primarily utilitarian components meant for functionality and stability rather than visual enhancement.
