Why is the toilet sewage lifter designed as an external pump?

The advantage of the sewage lifter of the external pump is that most of them come with a backwashing device, and the backwashing system has a high-pressure water column to clean the inner wall of the water tank at the same time when the equipment is running, so as to avoid impurities adhering to the inner wall of the water tank, and can be cleaned and maintained without cleaning, while the external pump does not have this function, so it is easy for impurities to adhere to the inner wall of the equipment box and cause equipment operation failure, the most important thing is that the equipment failure maintenance external pump is simpler, more convenient and more hygienic, because there is no need to open the box, The built-in pump needs to open the box to take out the pump from the sewage in order to quickly overhaul, and most of the pumps of Zede sewage lifters are external (microboy is used for sewage lifting in the bathroom, while SWH series is used for sewage lifting in kitchens, pantries and other places).
