What is a sump pump?
What types of pumps are available?
There are several types of pumps: cast iron pumps, plastic pumps, column pumps, submersible pumps and battery powered safety pumps.
Cast iron pump
The cast iron pump will have a longer life than other pumps because it is built stronger. In addition, it has a much higher resistance to overheating than other pumps since its casing absorbs the cold of the water and therefore protects it to a certain limit. The cast iron pump can be reconditioned since its housing is very durable unlike the plastic pump. It is also much quieter in general.
Lower quality pump often sold in big box stores. It has a very low resistance to overheating and its housing is not worth reconditioning. It makes more noise than a cast iron submersible pump. However, it is more aggressive in terms of purchase price.
The column pump is frequently used despite its low quality. Its motor is outside the water. It protrudes from the catchment basin which prevents the installation of an anti-radon basin cover. The adjustment of the float is very rudimentary and it is very noisy.
Battery operated pumps
There are battery operated submersible pump systems. These systems are installed to take over temporarily if a power failure occurs or if the primary pump fails. These systems are usually equipped with an audible alarm system to notify residents that the primary pump has failed.
What types of fleets are available?
There are two common types of fleets. There are vertical fleets and cable fleets.
The column fleet is a very reliable fleet. It consists of a float installed on a metal rod in a vertical position. When the water rises in the catch basin, the float rises and activates a mechanism that starts the pump. When the water drops in the basin, the float drops at the same rate as the water and the mechanism will stop at the desired height.
The cable float is a very common system. However, it has its drawbacks. It consists of a steel ball in a plastic float attached to the end of a cable containing power cables. As the water rises in the pond, the float rises with the water and once the level is high enough, the ball will roll down activating the pump. When the float drops, the ball will roll downward and cut off the power to the pump. However, these types of floats can sometimes cause problems because their cable can become clogged in the pond causing it to not work. Also, the internal ball can stick to the walls of the float and not activate properly if the water level is very high.
Which submersible pump should I choose?
We only use cast iron submersible pumps with vertical floats. These pumps are long term reliable, quiet and very efficient. There are all types of forces to properly evacuate the quantity of water to be pumped. A Lesage Excavation expert can evaluate your needs and suggest a pump that will meet your requirements.
