Check Your PSI

When buying accessories for water blasters or surface cleaners, double check the PSI rating of the water blasting equipment or pressure surface cleaners you are about to purchase. Some gear, such as system valves, are offered in the same configurations for both water blasters and surface cleaners, which have different PSI ratings. It is never safe to use an accessory rated for a lower PSI on a higher-rated pressure system. It is easy to overwhelm a lower-rated accessory with too much pressure from a high-PSI water blaster system, causing the part to rupture, break, or explode.
