sewage unit Termojet WT 400-A (4 in 1, for toilet)

Termojet WT 400-A — a macerator sewage lifting unit in a "4-in-1" format that solves the main renovation problem: how to install a full bathroom with a floor-standing toilet where there is no gravity-fed drainage. Basement, lower ground floor, a room cut off from the soil stack — the unit takes waste from four sanitary appliances simultaneously and forcibly discharges it to any point in the building.

Operating principle. Inside the sealed housing is a submersible pump with a macerator. After flushing the toilet or opening the drain of a basin or shower, the waste flows into the chamber where the macerator grinds the solid matter. The pump then discharges the liquid through a small-diameter pressure pipe — horizontally up to 80 m or vertically up to 8 m. An automatic float sensor switches the motor on and off without user intervention.

Applications. The WT 400-A with a DN100 connection is designed for a floor-standing toilet — this is what distinguishes it from model B (wall-hung toilet) and model C (without toilet). Three additional 40 mm inlets allow the connection of a basin, shower cubicle, bathtub, or washing machine. The unit is ideally suited for:

• installing a bathroom in the basement or lower ground floor of a private house;
• apartment renovation without relocating the soil stack — the drainage outlet is placed wherever convenient;
• converting a storeroom, wardrobe, or utility room into a bathroom;
• holiday homes and cottages with non-standard layouts.

Advantages of the Termojet WT 400-A. The unit is a worthy alternative to imported sewage lifting units of the same class at a significantly lower price. The design incorporates a service panel for maintenance without dismantling the entire unit. Quiet operation does not disturb sleep — the noise level is minimal thanks to the sound-insulating housing. The IPX4 protection class ensures safe operation in wet areas. The wastewater temperature range of 1–75°C allows hot water from a bathtub to be accepted without restrictions.

FAQ

Can two basins be connected to the WT 400-A? Yes — the unit has three 40 mm inlets that can be used in any combination: two basins and a shower, a bathtub and a washing machine, etc.

What pipe should be used for the pressure outlet? A polypropylene or multilayer (metal-plastic) pipe with a diameter matching the chosen outlet adapter (23, 28, 32, or 44 mm) is used for the pressure pipeline. The run is laid in a chase or behind a suspended ceiling.
