Grinder pump GRUNDFOS Sololift 2WC-1 (model 97775314) for wastewater lifting

The GRUNDFOS Sololift 2WC-1 grinder pump is designed to lift and discharge domestic wastewater when gravity drainage is impractical. The compact unit shreds toilet waste and household sewage so that effluent can be pumped under pressure to a sewer line or on-site treatment system. Intended for installations where sanitary fittings are below the level of the main drain, the pump supports reliable wastewater removal from basements, bathrooms, utility rooms and remote fixtures.

Advantages

The Sololift 2WC-1 combines a compact design with a macerator mechanism that reduces solids to a pumpable slurry, minimising the risk of blockages in pressure pipes. Constructed for domestic use, the unit offers straightforward installation and quiet operation relative to older designs. Its sealed housing and integrated impeller protect internal components from abrasive material in household sewage, increasing operational reliability. The unit is suitable for both new installations and retrofits where conventional gravity drainage cannot be achieved.

Suitable for

• Basement bathrooms and toilets below main sewer level
• Remote sanitary fittings such as showers, sinks and washing machines
• Small domestic installations lacking natural drainage fall
• Renovations and retrofits where connecting to a sewer requires pressure discharge

Key specifications

• Type: grinder pump for domestic wastewater
• Function: maceration of toilet and household sewage for pressure discharge
• Application environment: indoor domestic installations (bathrooms, basements, utility rooms)
• Connection: discharge to pressure sewer or treatment system (requires compatible piping and check valve)
• Design characteristics: compact unit with sealed housing and integrated macerator/impeller

How to use

Install the Sololift 2WC-1 in a dedicated installation space according to local plumbing regulations and the manufacturer’s instructions. Connect inlet fittings from the sanitary fixtures to the pump’s inlet and connect the discharge pipe to the pressure sewer or treatment system; include a non-return valve where required. Ensure electrical supply is provided by a suitably rated circuit and protected by an appropriate residual current device or circuit breaker. After installation, test the unit by operating the connected fixtures and verify that the pump activates, macerates the waste and discharges correctly without leaks or unusual noise.

Usage recommendations

Use the pump only for domestic wastewater; avoid introducing non-biodegradable items, large solids, feminine hygiene products, wipes, and aggressive chemicals that can damage the macerator or impair function. Schedule periodic visual inspections of connections and check for unusual vibration or sound. Follow local codes for backflow prevention and service access to ensure safe, trouble-free operation.
