Which factor determines the type of head you should use on a power rodder?

The type of head you should use on a power rodder is primarily determined by the obstruction that needs to be removed. Different heads are designed for specific types of blockages and conditions within the lines. For instance, a cutting head might be more effective for cutting through roots, while a heavier, more aggressive head could be necessary for removing grease or sludge buildup.

Using the correct head for the specific obstruction maximizes the efficiency and effectiveness of the power rodder, ensuring that the blockage is cleared without damaging the piping system. Each head type is engineered to handle certain challenges, which is why understanding the nature of the obstruction is crucial in selecting the appropriate attachment. This approach also minimizes the chance of repeated issues by addressing the problem effectively from the start.
