Description
Overview:
The Rubber Clack Valve for Honda WX10K1 Pump (part reference 78110-YE9-003) is a small but essential internal pump component made from moulded black rubber. It acts as a one‐way seal inside the pump to control fluid direction, prevent backflow, and help the pump hold prime between uses. This supports reliable starting and consistent flow on compact petrol water pumps such as the Honda WX10K1. Over time, rubber valves can harden or deform, reducing performance; replacing the clack valve restores proper sealing and flow. The form and material are chosen for a positive seat in the pump body and dependable operation with clean water. Suitable for routine maintenance or repair where reduced suction, loss of prime, or erratic output has been noticed.
Key Features:
- Direct-fit replacement for the clack/non-return valve in the Honda WX10K1 pump body
- Moulded rubber construction for reliable sealing and resistance to wear from typical clean-water use
- Helps maintain prime and prevents backflow, supporting easier starts and steady discharge
- Restores performance when the original valve has become flattened, nicked, or hardened with age
- Compact, lightweight part designed for straightforward installation with basic hand tools
- Precisely shaped seat face for repeatable closure and reduced leakage
- Supports pump longevity by reducing reverse flow and cavitation risk
- Honda reference: 78110-YE9-003 (also 78110YE9003) for accurate identification and ordering
Typical Applications:
Maintenance and repair of Honda WX10K1 portable water pumps used for garden watering, tank transfer, light site dewatering, irrigation set-up, and general clean-water movement. Ideal when the pump struggles to prime, loses prime quickly, or shows reduced flow due to a worn internal non-return valve.
