The higher the pressure (measured in pounds per square inch—psi), the tougher the cleaning jobs they can tackle. Both types require a steady, uninterrupted supply of water (in gallons per minute—gpm). For occasional use, most homeowners will find that a washer with a pressure range of 1,300 to 2,400 psi works best.

How does a pump sprayer work?
The pump forces this liquid down a narrow barrel and out a small hole at the spray valve. Inside the shroud, there is a small spring which compresses the fluid once pulled back by the trigger.

For this reason you should not let your pressure washer idle, not spraying water for more than a few minutes. Without cooling the pump head the temperature will begin to climb to 200+ degrees. When it gets that hot, water seals and o-rings soften and wear quickly. Valves can be distorted and warp.
What happens if you run a pressure washer without water?
If you start your pressure washer dry, its other inner components will also wear down. The motor, in particular, will overheat as it tries to turn the pump, which is under a lot of friction. When the motor overheats, it can lock up or even break down entirely.

How does a pressure feed spray gun work?
Pressure and Siphon-feed guns are the oldest of designs. In pressure guns the fluid is pressurized, allowing it to flow out (these aren’t used much anymore). In siphon guns the movement of the air inside creates a siphon that pulls paint out of the reservoir.
How does pump sprayer work?
The pump forces this liquid down a narrow barrel and out a small hole at the spray valve. Inside the shroud, there is a small spring which compresses the fluid once pulled back by the trigger.
