Real-World Cleaning Potential

Imagine tackling walls, fences, driveways, and vehicles with a dependable, responsive flow. The design focuses on consistent pressure delivery and durable components that stand up to frequent outdoor use. While results depend on your exact setup, the pump is engineered to handle demanding cleaning sessions with less downtime.

• Reborn Your Cleaning Power: 3400 PSI at 2.5 GPM suits broad surfaces and stubborn grime.
• Universal Compatibility: standard 3/4 shaft, NH garden hose inlet, and M22 high-pressure outlet support top brands like Simpson, Ryobi, and Honda.

Installation is straightforward and tool-friendly. The kit comes with a detergent hose, mounting bolts, a shaft key, spacers and washers, and a concise instruction manual, so you can set up in minutes and start testing the stream right away.

Durability and protection also come through in key features. A one-piece pump head delivers reliable sealing, a metal shaft sleeve guards against wear, and a thermal relief valve helps protect the pump during bypass operations.
