Tips For Maintaining Your Pressure Washer’s Power and Pump Components

No matter what type of pressure washer you have, the essential components are the same, be it gas-powered or electric. The engine will power a water pump to send water through an axial cam (or rotary lobe), which pressurizes the water in the pump and sends it out of one of several nozzles located on the tip of the pressure washer wand. Sometimes these nozzles are adjustable to control the type of spray pattern.

If you have a light duty pressure washer, the pump is probably the most critical component to keep in good condition. The pump pressurizes the water and sends it out of the nozzle. To help keep your pump in good condition, follow these tips:

Check for cracks in the pump

If you find any cracks in your pressure washer’s pump, replace it immediately. An attempt will cause severe damage to your engine when high-pressure water flows through it. The lack of a working pump cannot be easily repaired in the field and needs to be addressed as soon as possible.

Be sure to check the water inlet and outlet hose connections for cracks or leaks, too. If there’s a crack, replace those hoses immediately. A leaky connection will cause water loss and trouble with your pressure washer’s performance.

Look out for flaking paint on the pump casing

If you see any flaking paint on the casing of your pressure washer’s pump, there is a severe problem. The color will eventually flake off completely and expose rusting metal or cause pitting. If you have an older model with this type of pump, consider replacing it so that it doesn’t become a major headache in the future

The High-Pressure Hose and Nozzle

No matter what type of hose you have on your pressure washer, it needs to be inspected regularly for damage and leaks. The last thing you want is high-pressure water spraying out of a hole in the hose or nozzle! If any metal is showing through the covering, replace that section immediately.

Feel the hose for warmth

Before turning on your pressure washer, put your hand around the high-pressure hose close to where it is connected to the wand. If you can feel any warmth there, a spray of hot water will be released when you turn on the machine, which means that you have a low-pressure leak in that section of the hose. Replace it before using the device again.

Check your nozzle regularly if you have an adjustable one

Make sure that the nozzle is securely tightened on the wand at all times, but be careful not to over-tighten it, which will cause damage. Some nozzles also contain rubber washers that should be checked periodically to ensure they are in good condition.

The Spray Wand

Make sure that the spray wand is connected correctly to your pressure washer’s hose, and inspect it for damage before each use. Make sure that there aren’t any broken or missing plastic pieces. If you find cracks or breaks in the spray wand, replace it immediately

Check the oil

Before using your pressure washer, make sure that there is enough oil in the crankcase. If the oil level is low, add more before starting it.  Check around your engine for any leaks of water or other fluid, which are usually easy to spot if you know what you are looking for. Be sure to recheck the oil level after using the pressure washer. If it’s down, add more before storing.

Clean

Clean your pressure washer routinely with soap and water or an approved cleaner to prevent corrosion from taking place. Keep all exposed metal parts clean and dry at all times.

Check for loose bolts

If you find loose bolts, especially where the electrical wires or gas lines are attached to the pressure washer engine, tighten them securely. The last thing you want is for something to break free while you are using your pressure washer.

The Pump

Be sure to check your pump often for leaks. If it makes a loud “whistling” sound, the chances are that you leak somewhere in the pump. Many professional pressure washers come with stainless steel pumps that will not rust or corrode. These are usually more expensive but will last a very long time if well taken care of.

Final Words – Tips For Maintaining Your Pressure Washer’s Power and Pump Components

Keeping your pressure washer in good working condition is easy if you follow these tips each time before using it. However, if a problem develops, don’t hesitate to contact a service center for advice on fixing the problem and preventing it from happening again.

Your pressure washer is a significant investment. Proper care can provide you with many years of reliable service. If something breaks or wears out on your pressure washer, immediately replace it before using the machine again. Make sure to check all connections and hose sections for damage at least once a week during regular use.
