  • Q:
    Can I use this on my 3000psi costway pressure washer that I bought from you in 2018? It came with two tips One was a fan pattern spray that failed pretty quickly. The other was a round pattern sprayer that is still working good.
    This is not easy to answer, because I don’t know which pressure washer you bought in 2018. If you have problems with the after-sales of the product you bought before. Please forward your question or concern as well as the order number to our customer support at [email protected]. After order confirmation, our customer support are standing by and ready to help you resolve any issues you may have.
