A pressure washer, also known as a jet washing pumps, is a powerful cleaning tool used to remove paint, mildew, dirt, and grime from various surfaces like buildings, houses, vehicles, and concrete areas.
It works by using a motor (electric, combustion, pneumatic, or hydraulic) to power a high-pressure water pump, which pushes water through a small hole (tip) at high speed. This fast-moving water effectively cleans by hitting the dirt with force.
Different nozzles create various water jets for different cleaning needs. Some produce a wide fan-shaped spray, while others create a thin, powerful stream. Adjusting nozzles changes the pressure and flow rate of the water.
The pump in a pressure washer has pistons and valves like those found in engines. It can bypass water flow when the trigger is released or the tip is blocked to prevent damage.
It’s essential to choose a pressure washer with a durable pump, as some have short lifespans. Additionally, roots in sewer lines can be removed using powerful jet-cleaning pumps, but extensive root damage may require pipe replacement.
Hydraulic jetting equipment is used to clean tanks in RVs, using high-pressure water streams to remove deposits without harming the environment, unlike chemicals. This method is similar to pressure washing, which is used for various cleaning purposes like driveways, vehicles, and buildings.
