Setup and Installation
Follow these steps to properly assemble and install your DONGKER 3 Way Hose Connector:
- Prepare Components: Unpack all components and ensure you have the Y-distributor body, three hose connectors, and three rubber gaskets.
- Insert Gaskets: Place one rubber gasket into the threaded end of each hose connector. These gaskets are crucial for a leak-proof seal.
- Attach Connectors to Y-Body:
- Screw the hose connector without a valve onto the single inlet port of the Y-distributor body.
- Screw the two hose connectors with integrated valves onto the two outlet ports of the Y-distributor body.
- Connect Hoses:
- Select the appropriate hose diameter (25mm, 32mm, or 38mm) on each connector. If your hose is smaller, you may need to cut off the larger diameter sections of the connector to match your hose size. This ensures sufficient water volume and a secure fit.
- Slide your hoses onto the barbed ends of the connectors. For a tighter fit, you may briefly warm the end of the hose in hot water before sliding it on.
- Secure the hoses with hose clamps (not included) if necessary, especially for high-pressure applications.
- Final Check: Before turning on water, double-check all connections for tightness and proper hose fit.

Operation
The DONGKER 3 Way Hose Connector allows for efficient water distribution and control:
- Water Flow Control: The two outlet ports are equipped with individual ball core switches (red levers). Rotate the red lever to open or close the water flow to each connected hose.
- Full Flow Design: The large-diameter ball core switch design ensures that when fully open, it does not significantly impede water pressure, allowing for faster water inlet and shorter water outlet times.
- Applications: Use this connector to split water flow from a single pump or water source to multiple destinations, such as:
- Pond filtration systems
- Fish tank water changes or filtration
- Garden irrigation zones
- Rockery water supply and stream landscaping

Maintenance
Regular maintenance will extend the life of your hose connector:
- Cleaning: Periodically disconnect the hoses and rinse the connector with clean water to remove any debris or sediment that may accumulate, especially if used in pond or fish tank applications.
- Gasket Inspection: Check the rubber gaskets for cracks, hardening, or deformation. Replace them if they show signs of wear to maintain a leak-proof seal.
- Storage: During freezing temperatures, disconnect the unit and store it indoors to prevent damage from ice expansion.
- Valve Operation: Ensure the red levers operate smoothly. If they become stiff, clean the area around the ball valve.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaks at connections | Loose connections, damaged gaskets, incorrect hose size. | Tighten connections, inspect and replace gaskets if necessary, ensure correct hose diameter is used and secured. |
| Reduced water flow | Valves not fully open, debris inside the connector or hoses, hose kinked. | Ensure valves are fully open, disconnect and clean the connector and hoses, check hoses for kinks. |
| Difficulty turning valves | Mineral buildup or debris around the ball valve. | Disconnect from water source, clean the valve mechanism. |
