At 500 hours, it would only be under extreme circumstances when very dirty water was used, there were no adequate water filters, or the pump ran out of water or oil and suffered some damage. Therefore, when the pressure washer pressure drops, replace the nozzle. These three factors will wear out a nozzle at different speeds. The easiest way to tell if a nozzle is worn out is to look at the operating pressure on the pressure gauge and remember what it was when the unit was new.
If there has been a pressure drop of 10% or more, it's time to change the nozzle. And when a nozzle change doesn't make any difference, it may be time to recondition or replace the bypass valve (unloader) and only then will you bother to change the pressure pump gaskets. Most new and experienced pressure washer owners wonder if the tips of their pressure washers wear out. The simple answer is that they can, and they do over time.
With time and sustained use, the tips of the pressure washer wear out and wear out just like most tools. They can also wear out due to damage suffered during work or with proper storage. All pressure washers come ready to use with 3 or 4 color-coded nozzles. If you're not careful, then wondering if the tips of your pressure washer wear out will be the least of your worries.
However, the amount of pressure that pushes water out of the rod and through the tip will remain the same. You can usually start to tell if you need a replacement nozzle when the water pressure starts to drop. As mentioned above, make sure you've chosen the right type of nozzle for your pressure washer. Most washing machines come with a standard selection of nozzles with different sizes and pressure levels.
A telltale sign that the tip or nozzle of a pressure washer is worn out is that it's spraying in a wider way than usual. Over time, with normal and regular use of the pressure cleaning system, the tips and the nozzle may begin to degrade. If the wrong nozzle is selected, your pressure washer may not operate at optimal performance. The pressure level will remain the same, but the tip of the nozzle will have widened, so it won't accumulate as much power as it normally should.
Think of it this way: every colored tip you use in your pressure system has an associated grade. As with almost any other appliance or appliance, pressure washers and their nozzles will wear out over time. Keeping your pressure washer in good condition means knowing how it works and how to fix any problems. Today I'm going to show you how to match the nozzle of a pressure washer (also called a spray tip) to the cleaning surface to ensure quick and complete cleaning without damage.
You'll also want to take the time to prepare the pressure washer and engine before storing them in a long-term storage location (as you probably would in winter).
