sewage unit Termojet WT 400-B (4 in 1, wall-hung toilet)

Termojet WT 400-B — a macerator sewage pump unit "4 in 1" for bathrooms with a wall-hung toilet. If you are designing a modern bathroom with a concealed cistern installation but gravity drainage is unavailable or its installation requires extensive work — the WT 400-B is the only compact and effective solution.

How it works. After the toilet is flushed or the trap of a washbasin, shower cubicle, or bath is opened, wastewater flows by gravity into the unit's chamber. The built-in macerator grinds solid waste, after which the pump discharges the suspension through a small-diameter pressure pipe. An automatic float sensor controls switching on and off without manual intervention. The outlet can be configured for 23, 28, 32, or 44 mm pipe depending on the system configuration.

Applications. Model B differs from Model A in the toilet inlet design, optimised for wall-hung sanitary ware. The unit is suitable for:

• bathrooms with wall-hung toilets and concealed cisterns in basement and lower-ground floors;
• apartment renovations involving relocation of the bathroom without altering the soil stack;
• offices, salons, and small commercial premises requiring a bathroom;
• guest houses and small hotel rooms.

Advantages of Termojet WT 400-B. Three 40 mm inlets simultaneously serve a washbasin, shower cubicle, and bath or washing machine. The service-panel design simplifies maintenance without dismantling the sanitary ware. Quiet operation — the housing with sound-absorbing inserts reduces acoustic discomfort. Protection class IPX4 confirms safe operation in wet conditions. The wide wastewater temperature range of 1–75°C eliminates any restrictions regarding hot water from the bath.

FAQ

Is the WT 400-B suitable for a toilet with a horizontal outlet? Yes, provided an appropriate elbow fitting is used. The 100 mm inlet provides a standard connection to toilets with various outlet types via an adaptor.

At what distance from the toilet can the unit be installed? The unit is positioned directly behind or alongside the toilet — the distance between the toilet and the unit must be minimal for gravity drainage between them; pressure discharge then runs up to 80 m horizontally or 8 m vertically.
