Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this outlet pipe meets the exact dimensions and material standards of the original component it replaces.
- Correct Discharge Path — as the primary water discharge conduit, a properly fitted outlet pipe maintains full flow capacity and prevents pressure loss at the pump outlet.
- Fits WH15 and WH20 Water Pumps — designed for Honda WH15 and WH20 centrifugal water pumps; verify your serial number against the fitment table to confirm the correct application.
- Check Your Serial Number — Honda updates parts at production serial breaks, so matching your pump's serial number to the fitment data is the most reliable way to confirm this is the right pipe for your unit.
The outlet pipe is the discharge passage through which pressurized water exits the pump body and enters the connected hose or piping system. On centrifugal water pumps like the WH15 and WH20, the impeller accelerates water through the volute and directs it out through this pipe under pressure — a cracked, corroded, or damaged outlet pipe will cause leaks, reduced discharge pressure, and loss of flow volume. Replacing a worn outlet pipe with a genuine Honda part restores the pump's full discharge performance and prevents further water loss at the outlet connection.
