Frequently Asked Questions
Is the 550 gallon pressure washer trailer DOT-compliant?
The trailer is built with lights, safety chains, brakes, and a 2-5/16" ball coupler so it can be towed on public roads. Always confirm local DOT and licensing requirements for your state before hauling water at full capacity.

Most users apply detergents and degreasers through the downstream low-pressure soap injection system. Always follow the chemical manufacturer’s instructions and check compatibility with the pump, hose, and seals.
