How the DrainJet® Professional Works

The DrainJet® Professional expands hydraulically inside the pipeline to create a temporary seal against the pipe wall. Once pressurized, water flow is directed downstream to break up grease, sludge, sediment, leaves, soap residue, and other soft obstructions while flushing debris through the drainage system.

Typical Operating Procedure

Step 1: Connect DrainJet to Water Hose

Step 2: Insert DrainJet into Drain, even around bends

Step 3: Turn On water. DrainJet expands to lock into drain and flushes out clogs

High flow and jet action clears even tough commercial drains

The larger flow capacity of this model helps improve cleaning performance in larger drain systems where debris may accumulate over longer pipe runs. Warm or hot water may improve grease removal during operation.
