Everything you need to know about how basement sump pump systems work, their components, and why they matter.
A sump pump consists of several mechanical and electrical parts and components that work together to remove excess water automatically and protect your home against flooding.
A float switch is the device that detects the water level in a sump pump. It floats within the water or on its surface, moving up or down depending on the water level. When the water rises high enough, the float switch signals to the sump pump to start discharging water. When the water level decreases, the switch stops the pump.
The check valve is a vital sump pump part usually situated within the discharge line. It prevents water from backflowing into the sump pit once the pump has expelled it. Check valves open when the pump operates, allowing water to flow out, and close when the pump stops — ensuring the water does not return.
The discharge pipe carries water from the sump pump to a designated drainage area. Its primary function is to direct the expelled water away from the foundation of the home, preventing flooding and water damage.
The sump pumps we specify and install are automatic — they operate without manual intervention as and when needed. They are powered by electricity and require a mains connection. To operate effectively they must remain powered at all times. We also recommend battery-operated back-up pumps for use during power outages.
Battery-operated back-up pumps are vital should you experience a power outage during a period of water ingress — they continue to protect your home whilst you have the chance to restore the power source.
They are also valuable assets to have in place should your primary pumps fail for any other reason.
