As you probably already know, the flow of water depends on gravity. However, there are certain conditions that cause the water level to be lower than the ground level. In this case, it may be necessary to use devices such as a lift pump.

How does a lift pump work?

As the name suggests, a lift pump is used to raise water to a certain height. It, therefore, provides additional pressure for the water to flow into the pipes provided for this purpose. It can be used in different cases, namely:

• For the evacuation of wastewater
• To provide a greater flow of water,
• To empty water from a pond or a swimming pool

A lift pump consists of 3 main elements: a storage tank, a lift pump, and a control system. In some cases, its installation can be part of your plumbing work. To operate, the system is immersed in the liquid to be drained.

The control system, usually sensors, detects the level of water to be drained. The pump then starts an automatic process. The pump itself, which is equipped with an electric motor, will then suck up the liquid and discharge it into a discharge pipe. Note that the type of installation depends on the viscosity of the water. Indeed, pumps of different power will be necessary to evacuate clear water and water loaded (with mud, soil, sand, etc.).

When is it mandatory to use a lift pump?

You are responsible for the installation of the sewage disposal system from your property to the city sewage system. If the level of your land (and therefore of your pipes) is below that of the municipal sewerage system, you will probably need a lifting pump. There are certain cases where it is essential to use a lift pump to ensure the circulation of water.

The objective is to bring additional pressure to bring water to the pipes. As you may know, the force of gravity is often insufficient to “lift” the water. This device is also useful for evacuating wastewater from a room located in the basement of your house.

If you do not have a sewage treatment system, you will need a pump with sufficient capacity. On the other hand, if you already have a non-collective sanitation system, you can invest in a much less powerful device. Note that a lift pump needs maintenance. Otherwise, the storage tank may malfunction and overflow.

In what other cases can the sewage pump be used?

In addition to the removal of heavy wastewater, the sewage pump can also help in other situations.

Draining a pool

Of course, there are different ways of emptying a pool. You can use a garden hose or a siphon, but you can also use a lift pump. When you immerse it in the water, the device will automatically empty it from your pool. The water can then be evacuated into the rainwater collector or into the sewer system. However, you should know that authorization is required to empty a pool.

Draining after a flood

The lift pump is an interesting equipment to evacuate the water accumulated after a flood. Indeed, it will allow you to suck up all the water and evacuate it elsewhere quickly. You can always opt for submerged models. However, keep an eye on your pump so that it doesn’t run dry, which could damage the motor. If the water is muddy, use a dirty water pump. If the water is muddy, use a pump to clear the water.
