DTB’s pump stations come in a few different varieties. Whether it’s a single or dual pump system, the pump controllers act as the brains of the system. They help in switching the pumps on and off, as the name suggests. However, that’s not all there is to it. So, we will dive deep into this and explain to you all about this handy gadget.

So, what are pump controllers?

The ultimate goal of a pump control is to prevent possible damage to the pump system. What does this mean? It essentially implies that any pump is meant to work under a specified range of metrics, and these settings are also fed in the controller. Now, the pump controller’s job is to switch the pump off whenever the metrics are exceeded or go wrong in some way so that this doesn’t harm the pump.

This can include the water level in the pit being too high, or something get jammed between the impeller of the pump.

Both these cases will result in an alarm being sounded, which alerts homeowners that something has gone wrong with the pump system.

However, one thing to keep in mind is that pump controllers would function as intended only when the other parts feeding information to it are working well too. It is after all a part of the pump system.

What Do Pump Controllers Do?

Purpose of a pump controller

Here are the main components of a typical pump system:

  • Water pump(s)
  • Floats or level sensors
  • Pump controller
  • Valves & plumbing

Generally, a pump system uses either pressure sensors or mechanical float switches to register different water levels within a pit. Based on these readings, the pump controller protects the whole pump system that consists of these crucial components and protects the basement or home from flooding. Now, what is the main purpose of the pump control that ensures everything is running smoothly and safe? Let’s take a look:

A pump controller protects the pump and the pump system

As previously stated, the controller’s primary function is to protect the pump. Pumps are an expensive investment, so avoiding damage and extending their life will pay off.

When a heavy rainstorm hits, these pump systems can fill up very quickly and flood if not pumped out. The floats or pressure sensors will relay the water levels to the controller. The pump controller in turn, will tell whether one or two pumps to turn on, depending on the inflow of water.

The controller also has an inbuilt feature to alternate the pumps between uses.

In this way, not one single pump is overused, but instead, the load is shared between each other. In the long run, this protects the pumps and minimises their likelihood of breaking down.

Debris flowing into the pit such as rocks and leaves can cause the pump to jam and get blocked. Without a controller, pumps would normally keep trying to empty the pit to no avail, until either it overheats, or the motor coils of the pump are irreparably damaged. Fortunately, with the use of controller, the system trips out, isolating the area from the rest of the house, and prevents the pumps from burning themselves out. Plus, it sounds an alarm so that a technician can be called in to assess the situation.

Benefits of an automatic pump control

  • Shuts down the pump automatically when the water level is low and kicks it back on when the level is too high.
  • Unburdens you from having to turn the pump system on or off whenever the pressure fluctuates.
  • Protects your home from a highly potential flooding situation.
  • Saves energy.
  • Doesn’t require much plumbing and can be easily linked to your water supply system.
  • Is easy to troubleshoot.

Troubleshooting hacks for an automatic pump controller

  1. Don’t forget to check the guide or the manual that comes along with the pump controller. It is more than enough to help you out in most cases. You can search for answers for your specific model on the internet too.
  2. Try switching the system off and back on, either from the isolation switch or
  3. If the controller is not switching on or responding, try starting it manually once. There’s a reset button as well that you can try.
  4. If there’s still no solution in sight, you can contact the controller’s manufacturer for assistance.
