Pneumatic Pipe Dredge High Pressure Stainless Steel Kitchen Dredging Tool 
Push the air‑cylinder handle up and down to pump air. Select a pressure below 0.4‑0.9 MPa according to how severely the pipe is clogged.
Keep an eye on the pressure gauge while pumping air. Use the instant impact force of high‑pressure air to blast blockages out of the pipe.
If there are overhead obstructions or tight working space, connect the sealer (suitable rubber cup) with the hose. Hold the sealer firmly with both hands for drain‑unclogging work.
Fit the sealer tightly against the pipe opening. Pull the air‑release trigger quickly. Unclog obstructions by instantaneous air impact. Repeat the operation for better results.
