For effective jet cleaning, what should the operator control not exceed in jet velocity?

For effective jet cleaning, it is essential to control the jet velocity to maximize cleaning efficiency while preventing potential damage to pipes or plumbing fixtures. The optimal jet velocity generally falls within a range that allows for thorough cleaning without causing erosion or excessive wear on the pipe walls.

In this case, a jet velocity of 4 fps (feet per second) is considered the upper limit for effective jet cleaning. This speed is regarded as a balance between power and safety, enabling the jetting equipment to dislodge clogs and debris effectively without risking harm to the infrastructure.

Going beyond this velocity may lead to inadequate cleaning results or worse, structural damage to the pipes, making 4 fps a crucial threshold to ensure both performance and safety. Therefore, maintaining this velocity is vital for effective cleaning operations in collection systems.
