Your pressure washer can be leaking from the body as a result of bad seals or a crack in the pump body.
The pressure washer pump may have a pressure relief that is allowing water to leak out when you release the trigger and it could be stuck open.
If water leaks from a crack in the pressure washer pump itself, the entire pump must be replaced.
However, if you notice water leaking directly from the pressure washer pump and there's no noticeable damage, the internal piston seals are likely worn or broken and can be replaced.
The amount of force that a pressure washer puts out is between 1,500 psi to 3,200 psi although some larger pressure washers can put out 4,000 PSI and even as high as 30,000 PSI for very large pressure washers.
The difference between a pressure washer and a power washer is a power washes uses heat and pressure to clean things and a pressure washer uses only cold water at high pressure to wash things.
Other than the difference in temperature used the pressure washer and power washer are the same thing but one uses heat and the other doesn't.
Pressure washing is usually less expensive than power washing because it uses less water and isn't as intense as power washing.
Power washers are better for large jobs, while pressure washing is more suited to smaller tasks.
In inexperienced hands, a pressure washer can cause damage to homes or even to your car's paint, trim, or delicate parts.
High-pressure water can strip away protective coatings and even force water into vulnerable areas, leading to rust or electrical issues.
Pressure washers are incredibly strong, and can break skin and cause other injuries.
A pressure washer should never be used on any living thing—no humans, pets, or plants.
Don't use a pressure washer while working on a ladder or on your roof—the recoil could throw you off balance.
Vinyl siding can withstand a powerful gas pressure washer (2,500-3,000 psi).
Aluminum, stucco or soft-grain wood homes will do better with a less powerful washer (about 1,200-1,500 psi).
