sewage unit Termojet WT 400-C (3 in 1, without toilet)

Termojet WT 400-C — a macerator sewage pump unit "3 in 1" without a toilet inlet. This is the solution for cases where drainage from a washbasin, shower cubicle, bath, or washing machine is required without connecting a toilet — for example, in a utility room, sauna, laundry room, or when installing a second bathroom without a toilet.

How it works. Three inlets with a diameter of 40 mm accept wastewater from various sanitary fixtures. The submersible pump with macerator processes hair, textile fibres, and other matter entering from the washing machine or shower, then pumps the liquid through a pressure pipe to the sewage stack. An automatic float sensor activates the pump only when needed — immediately after the chamber fills.

Applications. The WT 400-C is the only model in the WT series without a toilet inlet — making it more compact and offering higher flow rate (125 l/min versus 116 l/min for models A and B). Typical application scenarios:

• laundry room or utility room in the basement — drainage from washing machine and washbasin;
• sauna or steam room with a shower section but no toilet;
• second bathroom or shower room on the basement floor of a country house;
• spa areas, massage rooms, nail studios with drainage from foot baths.

Advantages of Termojet WT 400-C. The absence of a 100 mm inlet simplifies installation and reduces dimensions — the unit takes up less space. A flow rate of 125 l/min ensures rapid pumping even with all three connected fixtures operating simultaneously. The service panel opens without dismantling the entire system. Protection class IPX4 and a temperature range of 1–75°C guarantee reliable operation in wet and warm rooms. The unit is a worthy replacement for imported sewage pump stations of the same class, with a better price-to-quality ratio.

FAQ

Can two showers be connected to the WT 400-C simultaneously? Yes — all three 40 mm inlets are equivalent, so any combination is possible: two showers and a washbasin, a bath and two washbasins, etc. The 125 l/min flow rate handles simultaneous load.

Is the unit suitable for a sauna with a wastewater temperature exceeding 60°C? Yes, the wastewater temperature range of up to 75°C covers any water from a shower or bath, including hot drainage from a sauna.
