Pressure washer is a power tool that sprays water at high pressures to clean large, sturdy surfaces such as buildings, farm equipment and roads as well as sidings of the houses and patio. Water is drawn with a hose pipe and the water is pumped out at different levels of pressure according to the requirements of the machine. They are available for all levels of cleaning tasks from weekend projects to heavy-duty commercial applications. It delivers extreme pressure and can cause serious injuries if misused. It doesn't have very long life spans which the best models could last several years. Aside from the life span of its prone to deter by the following intrusions and conditions that might killed their operational performance.  Proper care and maintenance is the key to avoid these pressure washer killer conditions.

Top 12 Pressure Washer Killers

Pressure Washer Killer 1. Lack of Power

Like any other machine, the wrong power supply will greatly affect its use. Power supply is the first and easiest thing to check when water pressure drops.

Pressure Washer Killer 2. Insufficient Water Flow

Each pressure washer is rated to operate at a specific rate of water flow. This is usually expressed in GPM (gallons per minute). When not sure, users should check that they are operating their pressure washers at the correct GPM by checking their owner's manual. Sometimes a performance issue is that simple.

Pressure Washer Killer 3. Dirt or Build-Up

Any kind of dirt or build-up in a pressure washer is bad. This means the entire path of water through the machine must be dirt and buildup free. Gunky valves and valve O-rings will decrease performance and increase wear on components. If dirt somehow gets into the pressure pump, the pressurized conditions make it easy for the pump to be internally damaged. All in all, completely flushing a pressure washer before and after each use will save many problems with dirt in the system. And just a few minutes cleaning valves will help a washer run its best.

Pressure Washer Killer 4. Air in the System

Air might even be worse for a pressure washer system than dirt. Air in the system will cause sputtering pressure at the exit end of the gun. If air gets into the pressure pump, the pressure can cause little mini "explosions" that effectively chip away at the inside of the pump. Air can easily be removed from the pressure washer system by bleeding.

Pressure Washer Killer 5. Check for Blockage

Any kind of other blockage along the path of the water should be noticeable right away due to a drop in performance. Check grains of sand in valves, bent or kinked hoses, material in the nozzle, and excessive debris in the intake filter.

Pressure Washer Killer 6. Wrong Component

The parts must match the rating for that washer's specs in order for it to run correctly. That includes regulator, unloader, gun and the nozzle. Mismatching any other part will almost always cause performance problems right away.

Pressure Washer Killer 7. Leaks in the Component

A leak in a hose, in a valve, around an O-ring, in the gun, or anywhere else along the water path will drop the water pressure. Leaking hoses and guns should be replaced. If cleaning valves and O-rings does not stop leaks, they should also be replaced.

Pressure Washer Killer 8. Incorrectly-adjusted Unloader

Tightening or loosening the adjustable spring, located in the unloader valve will set the threshold pressure. An unloader will begin diverting water away from the pump. Adjust the unloader spring to increase or decrease the pressure of a washer. Some low and high pressure problems can be caused by a miss adjusted unloader. Its advisable to seek professional help to adjust the unloader for you, unless you are confident with what you're doing.

Pressure Washer Killer 9. Overwork due to Hot Water

Do not run hot water unless the pressure washer is specifically a hot water model. This can overwork the pump and other components very quickly.

Pressure Washer Killer 10. Needs Oil Changing

If it's a gas-powered washer, changed oil according to the instructions in the user manual. This is usually about every 50 to 100 hours or operation.

Pressure Washer Killer 11. Broken Drive Belt

For gas-powered washer that use belt-drive system, the belt should be checked often and replaced as necessary.

Pressure Washer Killer 12. Worn Parts

Wearing or damage to any part in the engine or along the flow of water should receive immediate attention. For example, a faulty regulator can either not allowed enough water through to the power pump, or it can let too much through, overworking the pump. A malfunctioning part anywhere in the system is likely to damage other parts if its used before repairs are made. Most worn or faulty parts have to be spotted by visual inspection.
