Sump pump is a pump used to remove water that has accumulated in a water collecting sump basin, commonly found in the basements of homes. The water may enter via the perimeter drains of a basement waterproofing system, funneling into the basin from rainwater or natural ground water, especially if the basement is below the water table level. Sump pumps are used where basement flooding happens regularly and to solve dampness where the water table is above the foundation of a home. Sump pumps send water away from a house to any place where it is no longer problematic, such as a municipal storm drain or a dry well.

Types of Sump Pumps

There are two primary types of sump pumps: submersible and pedestal pump.

• Submersible sump pumps are installed inside the sump pit and are sealed to prevent electrical short circuits. Since these pumps are submerged in water, they are generally quieter and tend to have a longer life because the water cools them during operation.
• Pedestal sump pumps have the motor mounted above the sump, making them easier to maintain and repair but louder and more obtrusive. They are typically used when the sump pit is shallow and narrow.

Components

A sump pump system includes several key components:

• Sump Pit: The pit, or basin, collects excess water. It is usually installed at the lowest point of the basement floor.
• Check Valve: This valve prevents the backflow of water, ensuring that water only moves out of the sump pit.
• Discharge Line: The line that carries water from the pump to the outside of the home.
• Float Switch: This switch activates the pump when the water level in the sump pit reaches a certain height.

Operation

The operation of a sump pump is relatively straightforward. When the water level in the sump pit rises to a predetermined point, the float switch activates the pump. The pump then moves water out of the pit through the discharge line. The check valve ensures that water does not flow back into the pit. Most sump pumps are equipped with a battery backup system to ensure operation during power outages, which are common during heavy storms when the sump pump is most needed.

Maintenance

Regular maintenance is required to ensure the reliable operation of a sump pump. This includes checking the operation of the pump by pouring water into the pit, inspecting the discharge line to ensure it is not blocked or frozen, and cleaning the sump pit of debris. It is also important to check the battery backup system periodically.

Installation

Installation of a sump pump should be done by a professional, especially if modifications to the home's electrical system are needed. Proper installation ensures that the pump operates efficiently and effectively, reducing the risk of basement flooding.

Conclusion

Sump pumps are a critical component in preventing basement flooding and water damage in homes. By understanding the types, components, operation, and maintenance of sump pumps, homeowners can ensure their basements remain dry and their homes protected from water damage.
