If it’s time to change the water pump oil in your pressure washer, then this article is for you. If you aren’t sure as to when you should change it, consult your user manual. This will specify an oil change based on the number of hours the washer has been used. That being said, it’s always a good idea to keep track of how many hours you use your washer so you’ll know when it’s time for an oil change. Other signs that show it’s time for a change include oil leaks and oil that is a milky color. Some tools you will need to complete the job include:

  • Oil catcher. A pan or other item that will be used to catch the oil as it makes its way out of the pump casing. You can use anything from an actual oil pan to an aluminum cooking/baking tray.
  • Although many washers have plastic knobs that allow for easy access, some models come with bolts instead and will require the use of the correct size wrench.
  • Oil funnel. This will help you avoid spills when refilling the pump assembly with new oil.
  • Storage container. Choose a container to store the old oil until it can be recycled or properly disposed of. You can use a 2-liter soda bottle or put it into an old oil bottle. Some stores will accept used oil, such as Walmart, Home Depot, Costco, Jiffy Lube (or somewhere similar), mechanics shop, and local recycling centers. If you’re unable to find a recycling center, call your local dump and see if they will accept it.
