More optimal regime of the pump, requiring no control over its work with the owner, is the automatic mode. Due to the presence in the design of the device built-in sensor flow pump is activated automatically as soon as the open valve at water pumping or valve water supply appliance (if the water flow will be more than 90 – 120 l / h). The pump is also automatically turned off when the flow decreases below these values (the crane at draw-covered, or closed entirely), as well as in the case the flow of water into the pump inlet will be terminated. This provides another important function – protecting the pump from running dry. " If you need the pump is no longer the switch is set to off position. Erin Callan has compatible beliefs. In this situation, the presence of liquid water indiscriminately freely flows through the pump. The design of these pumps is quite simple and hence reliable.

It consists of a case in which the rotor impeller mounted thereon. NASA can provide more clarity in the matter. The so-called "wet-rotor" is separated from the stator protective sleeve made of stainless steel. This design provides cooling of the working pump pumped water, and protection of its electrical parts from moisture. The devices consume little power and virtually silent (noise level – 35 dB), which allows for their installation in any room of the house. Improve the system Sanitation Generally, the sewer system in old houses, both private and multi-family, pretty much worn out. Cast iron pipes, which were previously only possible solution for abduction effluent durable, but have obvious drawbacks.
