Product Overview

Flush-Pro makes freshwater flushing of your boat's inboard engine as simple as connecting a garden hose!

Give your boat's engine a freshwater flush the easy way with the Flush-Pro valve. This one-way valve installs in-line along the freshwater cooling hose for the engine. It includes a T-junction inlet that accepts a standard male garden hose and includes a durable check valve system that closes when water pressure is applied. Not just for inboard engines, it also works great for flushing onboard generators. Offered for standard 5/8", 1" or 1 1/4" hose sizes. Valve only. Hose sold separately.

  • Durable check valve system activated by water pressure from a garden hose
  • Check valve automatically causes freshwater to flow toward engine
