Electric vs Water Powered Sump Pump
In the occurrence of a power outage a water powered sump pump is generally used to support an electric sump pump. There are several different types of sump pumps, and they all displace water, usually taking water from basements and moving it outdoors; they just do it in slightly different ways.
Electrical Sump Pumps
There are two types of electrical sump pumps. The first is a pedestal sump pump, which works well when the basement needs recurrent draining. The motor is turned on when the water arrives at a certain level. This type is not very expensive, although it is noisy.
Submersible is the second type of sump pump, and it works underground; it is turned on in much the same way as the pedestal pump. The submersible costs a bit more, but it's quieter than the pedestal and it has a longer life.
Water Powered Sump Pumps
This type of sump pump is turned on in the identical manner as the electrical pumps, however, they work by using the pressure of the water from the house's plumbing. Water powered pumps work at nearly the same speed as the electric types. The water powered pumps can work in conjunction with electrical types, which is convenient if the power goes out.
