Tips to Keep Your Pressure Washing Equipment in Top Shape
Pressure washers are powerful tools and just like vehicle require regular maintenance. A reliable Jet wash properly maintained will ensure long-term performance. In this article, we will share tips on how to maintain your pressure washer, including the benefit of using fresh petrol, regular oil changes, checking and replacing damaged o-rings, and how to avoiding dry running at all costs.

Pressure Washer Maintenance
Regular maintenance is essential to keep your pressure washer in good condition. Here are some tips for maintaining your pressure washer:
- Clean the unit the water tank you use to supply water for your pressure washer. There can be a buildup of dirt and debris inside the tank. When its empty use a damp cloth or soft brush to remove dirt and grime once you’re finished.
- Clean your pre water filters to ensure debris does not run through your pressure washer at after each job.
- Check the oil level and quality before each use, and top it up or change it as needed. Refer to your equipment manual for specific instructions. We do this as part of a precheck system we follow before turning on the pressure washer.
- Check the air filter regularly and clean or replace it if it is dirty. A dirty air filter can cause the engine to work harder, reducing its lifespan. We check this once per week.
- Inspect the hoses and connections for signs of wear or damage, and replace them if necessary. Damaged hoses or connections can lead to leaks or a drop in pressure, which can affect the performance of your pressure washer. This doesn't have to be complicated, look at the o’rings, unravel all your hoses and visually inspect the hoses… If you can see any exposed wire, you need to replace the pressure hose.
- Store the pressure washer in a dry area to prevent rust and other damage. Pressure washers are very robust. In the UK our biggest threat is the frost in the winter so ensure no water is in the system especially the pump.
Using Fresh Petrol in Your Pressure Washer
Using fresh petrol is crucial to the performance and lifespan of your pressure washer:
- Try to only use fresh petrol that is less than 30 days old. Petrol that is too old can damage your equipment and cause it to run poorly.
- Store petrol in a cool, dry place away from sunlight and other heat sources. Direct sunlight can cause petrol to evaporate more quickly and loose it potency..
- Choose petrol with the right octane rating for your equipment. Refer to the equipment manual to determine the recommended octane rating.
- Avoid using petrol with ethanol, as it can damage the engine over time.
Regular Oil Changes in Accordance with the Pressure Washer User Manual
Regular oil changes are essential to maintain the performance and longevity of your pressure washer. Here are some tips for changing your oil:
- Your pressure washing manufacturer will recommend oil change intervals. The frequency of oil changes depends on how often you use your equipment and the manufacturer's recommendations. There will be oil for the engine, gearbox and pump.
- Before changing the oil, warm up the engine for a few minutes to help it flow more easily
- Turn off the engine and disconnect the spark plug wire before changing the oil to prevent any accidental starting
- Use the correct type of oil recommended in the manufacturers manual, and ensure that you change the oil filter when necessary.
Check and Replace Damaged O-rings on Clamps and Connections
Damaged o-rings can cause leaks and reduce the pressure of your pressure washer. These commonly wear but here are some tips for checking and replacing damaged o-rings:
- Inspect the o-rings on clamps and connections for any signs of wear, cracks or breaks. If you notice any damage, replace the o-ring before using your pressure washer because prevention is better than reactive maintenance.
- Remove the damaged o-rings and clean the groove before installing the new one. Use a small amount of lubricant to help the o-ring fit more easily, vaseline works great.

Don't Dry Run a Pressure Washer
Dry running a pressure washer means running it without water, which can cause serious damage to the pump. Here are some tips to avoid dry running:
- Always connect a water supply to the pressure washer before starting it.
- Turn off the engine immediately if you notice that the water supply has been interrupted or there is a loss of pressure. This can appear as a “spluttering”.
- Ensure the water filter is clear and not blocked. This can reduce the water flow and starve the pump.
