Choosing the right nozzle for your pressure cleaner can seem like a daunting task. There are several sizes and spray types to choose from, as well as maintenance required for the nozzle.

This guide will go over why nozzle size is important, what types of nozzle is best for the task, the different types of nozzles that can be used, how often you should replace the nozzle on your pressure cleaner as well as the a high pressure nozzzle. 

One of the most common problems in pressure cleaners of every make is premature pump failure, most often caused by cavitation.

So, what is cavitation on a pressure washer system?

Cavitation is the formation & accumulation of bubbles in the pumping chamber on your high pressure pump & when these bubbles are put under pressure they collapse or burst which can create tiny but violent implosions inside the water effecting the surrounding parts. 

The 2 most common causes of cavitation happening in your pressure cleaner system are internal bypassing and sucking air.
