The household downhole electric pump (well) is designed to supply clean water in domestic conditions from wells or from open reservoirs. The pump is equipped with a float switch that prevents the pump from running without water. The float is adjusted to a certain water level, at which the pump turns off. When installing the pump in a well, provide enough space for the float switch to operate. You also need to make sure that at a minimum water level, the float turns off the pump. By adjusting the length of the float cable, it is possible to achieve operation at different water levels.
