Wastewater macerator pump GRUNDFOS SOLOLIFT2 WC-3, model 97775315

GRUNDFOS SOLOLIFT2 WC-3 is a compact wastewater macerator pump designed for use in domestic sanitary installations where gravity drainage is not possible. The unit receives waste from toilets and other bathroom fixtures, macerates solids and pumps the effluent horizontally or vertically to the building sewage line. Its compact dimensions and integrated macerator make it suitable for retrofits and installations below or behind fixtures, allowing flexible placement of toilets, showers and washbasins.

Advantages

The SOLOLIFT2 WC-3 combines maceration and pumping in a single compact unit that reduces installation space and simplifies connection to existing plumbing. Built for quiet operation and reliable performance, the pump minimizes the need for intensive maintenance thanks to its durable macerator cutting system and corrosion-resistant housing. Its design supports easy mounting and straightforward electrical and hydraulic connections for faster commissioning.

Suitable for

• Adding a toilet in basement or below-dwelling level where gravity discharge is impossible
• Installing a shower, washbasin or bidet in a room located away from the main soil stack
• Retrofit projects where minimal space and concealed installation are required

Key specifications

• Application: maceration and pumping of domestic wastewater including toilet waste
• Installation: concealed or semi-concealed below or behind sanitary fixtures
• Pumping direction: capable of horizontal and vertical discharge to the sewer connection

How to use

Mount the SOLOLIFT2 WC-3 unit according to local plumbing regulations and the manufacturer’s installation instructions, ensuring secure mechanical fixation close to the sanitary fixture it serves. Connect inlet fittings to the toilet or other fixtures and route the discharge pipe to the building’s sewage line, maintaining appropriate support and slope for the discharge run. Make the electrical connection using a qualified electrician and provide proper earthing and protection as required by local codes. After installation, perform a functional test by operating fixtures to verify that the macerator engages, pumps effluent to the sewer and that there are no leaks.

Usage recommendations

For reliable long-term operation, avoid disposing of non-biodegradable items, sanitary products or excessive fibrous materials into the macerator unit. Follow periodic inspection for wear of the macerator components and check seals and pipe connections for integrity. Use the appliance within typical domestic wastewater temperature limits and consult the product manual for specific installation clearances and service intervals.
