Bleeding a high-pressure washer FAQ
Yes. Bleeding before each use ensures trapped air is removed, which helps maintain consistent pressure and protects the pump from damage.
If the washer is not bled, air pockets may cause uneven pressure, reduced cleaning performance or even pump damage over time.
Usually less than a minute. Hold down the trigger until you see a steady stream of water coming from the nozzle.
Air can enter through the hose, connections or during storage. Bleeding the washer pushes this air out before use.
