Products Description
Commercial Drain Cleaning truck is a specialized vehicle used for professional drain cleaning services in commercial establishments such as restaurants, hotels, hospitals, and office buildings.
The truck is equipped with a powerful and efficient drain cleaning system that is capable of unclogging and cleaning various types of drains, including sinks, toilets, floor drains, and main sewer lines. It is an essential tool in maintaining the proper functioning and hygiene of commercial plumbing systems.

The truck's main feature is its high-pressure water jetting system, which consists of a large water tank, a high-pressure pump, and a set of specialized nozzles. The pump provides a steady flow of water at high pressure, typically ranging from 2000 to 4000 PSI (pound-force per square inch), which is capable of cutting through the most stubborn blockages and debris in drains.
