Insert Hydro Jetter Hose into Drain

What happens here

With the pressure washer running but the trigger *not* squeezed (no water flowing through the hose yet), carefully feed the hydro jetting hose into the entrance of the clogged drain or culvert. Push the hose as far into the pipe as possible until resistance is met or a significant length has been inserted. This ensures that when the pressure is activated, the high-pressure jets are contained within the pipe, preventing water from spraying back aggressively and allowing the rear-facing jets to propel the hose forward into the clog.

Goal: Carefully feed the hydro jetting hose into the clogged drain or culvert as far as it can go before activating the high-pressure water, to prevent uncontrolled spraying.
