A sump pump is indispensable in any home with a basement.
Basements are prone to damage because of dampness that happens during changes in weather conditions.
They are also highly susceptible to flooding during rainy season.
To keep your basement dry and useful for storage, you need to have some sort of basement waterproofing system that will accumulate the water down and away from your basement.
Such a system would have great use for a submersible sump pump.
A sump pump relocates and collects moisture and water that has accumulated in the basement, and concentrates the water towards a sump pit.
Sump pumps have to major kinds: the submersible and the pedestal kind.
Why Go for a Submersible Pump? Since a submersible pump goes inside the sump pit together with the motor, it creates less noise than a pedestal sump pump.
It stays hidden and does not take up space inside your basement.
It may also be more effective in draining your basement water than a pedestal pump, because a submersible pump can contain higher volumes of water.
Also, if your sump pit water can get tiny particles in it, a submersible is more capable of handling water with solid components.
A submersible pump is ideal for use in basements that are used for living or recreation, or if you have children and pets inside the house.
The danger of a pedestal sump pump is that its motor is exposed and could potentially be tampered with by kids or animals.
With a submersible pump, this concern is literally buried to the ground.
Options for Your Submersible Sump Pump Submersible pumps for your sump pit may have one among four different types of switches or floats.
A pedestal has only a tether float kind of switch.

• Tether floats - These kinds of floats hang on the side of the pump.
  They float when the water level inside the pit rises.
  
• Vertical floats - Vertical floats are attached to a rod and a ball inside the pit.
  With slight movement these floats move up and down
• Diaphragm - a diaphragm switch mimics a drum by becoming concave with increased water pressure.
  In turn, it activates the pump in the sump pit.
  
• Probe - This switch is controlled by a microprocessor.
  The technology senses water pressure and activates the pump.
  

Other Considerations Take note that even though a submersible sump pump possesses a slew of benefits versus a pedestal pump, it also has its own set of disadvantages.
For example, a submersible pump is harder to repair and clean than a pedestal.
The pump needs to be turned off and extricated from the pit itself before it can be replaced.
Also, submersible pumps are somewhat more expensive than pedestal ones.
They might also need to have repairs more often than a pump motor that does not get wet.
