Before you spend your hard earned money, ask the Manufacturer what is the Maximum Operating Pressure of their Machine.
Remember even though the Spec of the Pump says say ie. 2500 psi does not mean it will operate at that level.
In most cases they will say up to 1200 psi. The reason is, that their Heater Coils are made of Copper (Low Burst Pressure Rating) so anything above that pressure will damage the unit. Usually they will put a constant Bleeder Orifice Jet to 'Cap off' the Top end of the pressure capability of the Pressure Pump in order to prevent you from going any higher than what the Copper Coils are Rated for.
As Owner of Blue Baron, I want too give the Truck Mount Shoppers as much useful Information as possible before you make that purchase.
A lot of Manufacturers don't like this level of transparency that uncovers the 'Truth' that lies beneath the Louvered Cabinetry of these over priced Truck Mounts.
Smaller Engines, Blowers and Water Pump Systems incapable of delivering adequate pressure to do the many jobs like described above in the video.
Here are Specs of Truck Mounts where Pricing vs Performance is in the"Red"
