So as to avoid environmental pollution. Water tanks are used to replace collecting wells in sewage risers. Generally speaking, except for the water inlet, the water outlet and the exhaust hole, the whole equipment is in a closed state, so that the sewage will not contact with the soil and will not emit odor, which can be said to completely avoid environmental pollution.
Save space. In order to meet the requirements of Code for Design of Water Supply and Drainage in Buildings, the collecting well generally occupies a large area, while the performance of the water pump in the sewage riser is more stable and fully automatic, that is to say, as long as the water level in the water tank reaches the start-up level, the water pump starts to drain, so the function of the water tank is not to store water, but to flow, so the space occupied is small. Like Zede, the effective volume of microboy sewage lifting device used in basement single bathroom is only 18L, which can be directly connected to the back bathroom, while the effective volume of kompaktboy sewage lifting device used in multiple occasions and one machine lifting is only 55L.
Convenient maintenance and repair. Once the water pump of the traditional sewage collection well fails, people will inevitably come into contact with dirty water during maintenance, while the water pump of Zede's sewage lifter (especially the sewage lifter used for sewage discharge) is installed outside, so it will not come into contact with dirty water during maintenance, which is also convenient for operation and reduces the related maintenance and repair costs. In terms of maintenance, the drainage mode of the collecting well needs to be cleaned regularly. The drainage riser dedicated to Zede Sanitary Ware is designed with automatic backwashing function, and at the same time, there is a high-pressure water column to automatically clean the inner wall of the box, which is completely unnecessary for manual operation and more convenient.
