4. Setup
Follow these steps for initial setup:
- Placement: Position the waterworks on a stable, level surface, protected from direct weather exposure and frost. Ensure adequate space for ventilation and connections.
- Suction Line Connection: Connect a suitable suction hose (not included) to the pump's suction inlet. Ensure the suction hose is airtight and has a non-return valve at the end submerged in the water source (well, cistern, rainwater tank). The maximum suction height is 8 meters.
- Pressure Line Connection: Connect the pressure line (e.g., garden hose) to the G1'' outlet. The G1'' connection size allows for easy attachment of conventional garden hoses.

- Filling the Pump: Before first use, fill the pump housing completely with water through the designated filling opening until it overflows. This is crucial for priming the pump.
- Pre-filter: The integrated, removable pre-filter prevents damage from coarse dirt particles entering the pumping unit. Regularly check and clean this filter.

- Power Connection: Connect the power cable to a properly grounded electrical outlet.
5. Operation
The Scheppach HWW1400 is designed for automatic water supply in your home and garden, utilizing resources from wells, rainwater barrels, or cisterns. It is particularly suitable for frequent withdrawal of smaller water quantities, such as for toilet flushing.
- Automatic Operation: The integrated pressure switch automatically turns the pump on when water is drawn and the pressure drops below 1.5 bar, and turns it off when the pressure reaches 3 bar.
- Pressure Tank: The 24-liter pressure tank stores water, allowing the pump to operate more efficiently and reducing energy costs by preventing frequent short cycling for small water demands.
- Monitoring: The integrated pressure gauge displays the current tank pressure.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your waterworks:
- Pre-filter Cleaning: Regularly inspect and clean the removable pre-filter. Turn off the pump and disconnect power before opening the filter housing. Rinse the filter under running water.
- Winterization: Before the first frost, completely drain all water from the pump and connected hoses to prevent frost damage. Store the pump in a frost-free environment.
- General Cleaning: Keep the exterior of the pump clean. Use a damp cloth to wipe off dust and dirt. Do not use aggressive cleaning agents.
7. Troubleshooting
Refer to this section for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply Motor protection activated Pressure switch malfunction | Check power connection and fuse Allow motor to cool down Check pressure switch settings/function |
| No water delivery / Low pressure | Pump not primed Air in suction line Suction line blocked/leaking Pre-filter clogged Water level too low | Refill pump with water Check suction line for leaks, tighten connections Clean pre-filter Ensure sufficient water in source |
| Pump runs continuously | Leak in pressure system Pressure switch faulty Non-return valve faulty | Check all connections and hoses for leaks Inspect/replace pressure switch Check/replace non-return valve |
If the problem persists after attempting these solutions, please contact customer support.
