You can use an automatic pressure controller for your domestic or household water supply, equipped with a pump to manage the pressure of your shower, sinks, sprinklers, and more. They’re useful when combined with a domestic pressure booster pump or a rainwater tank pump.
Here are some of the essential applications of an automatic pressure controller:
It controls the pump to ensure it runs at a constant flow.
When showering at home without a pressure pump or automated pressure control, you might notice the water’s inconsistent temperature or intermittent water pressure. With a device that maintains a constant water flow, you’re bound to enjoy your showers a lot more.
It automatically starts and stops the water pump whenever you open or close a tap or valve.
With an automatic pressure controller, you don’t need to turn on your pressure booster or pressure pump every time you want to take a shower or wash the dishes. By opening a tap or sink, the electronic controller will automatically start the pump.
It protects your water pump from damage with its built-in features.
By installing an automatic pressure controller, you add an extra layer of protection to your water pump. As you probably know, many factors can cause a water pump to break, such as running dry, leaks, flow switch jamming, water shortages, and more. An automatic pressure controller is designed to help prevent all of these problems and more.
How Does An Automatic Pump Controller Work?
Now that you know what an automatic pump controller is and what it can do, let’s talk about how it works.
Basically, an automatic pressure controller is a motor that will automatically switch on when water in the overhead tank (OHT) falls below the lower limit and vice versa. The circuitry behind it is straightforward, minimizing the potential for electrical issues, and it is very energy efficient too. It is powered by a 12-volt DC power supply, which consumes around as much power as charging your phone.
Without getting too technical, an automatic pressure controller relies on the water pressure to operate. Using automatic pressure control will eliminate the need for all the other components in a traditional water pressure control system, making the plumbing in your home less complicated (and less expensive too).
With less complex controls and more automation – not to mention the absence of a pressure tank, – adjusting the water pressure in your home just got a whole lot easier.
Pros and Cons of an Automatic Pump Controller
Pros of Automatic Pump Pressure Controllers:
Automatically stops the water pump from running dry and overheating when the water supply is running out
Makes your plumbing or irrigation system more efficient, meaning you’ll save water and possibly electricity as well
Automatically activates the electric pump, so you don’t need to stand by the water pump to turn it on or shut it down manually
Runs on 12V DC power, meaning it is energy efficient
When shut down, the auto-restart feature periodically checks if there is a water supply, so you don’t have to turn it on again manually
The circuitry is less complicated than using a traditional water pressure system, meaning the plumbing is less cumbersome and troubleshooting is much simpler
Cons of Automatic Pump Pressure Controllers:
Automation can have its disadvantages, as an automated device isn’t typically prepared for every possible scenario
As it is an electronic device, the circuitry required a proper and secure cover, and the device can be damaged if water gets inside
It Maybe challenging to install in some old houses or existing older-style plumbing networks
An electrician may be required to connect an automatic pressure controller if not pre-integrated with a water pump
Durability and longevity can vary depending on the price point – more expensive devices will inevitably deliver better results and offer more features
Technology can still be challenging and unfamiliar for the older generations
Significantly more expensive than manual pressure control valves
How Do You Adjust an Automatic Water Pump Pressure Controller?
Most automatic pump controllers for household use have set cut-in and shut-off points, so they don’t require adjusting. More advanced models can have customized pressure settings within a suitable range, which can be easily adjusted using buttons on the face of the controller.
Automatic Pump Control Troubleshooting
To prevent automatic pump control failure caused by leaks and electrical problems, consider:
If not already sealed, install a cover to protect the electrical components from water damage.
If recommended by the manufacturer, use Teflon tape when installing to prevent any leaks.
Make sure you consider using a barrel union between the pressure controller and the electric pump. It can be beneficial for future repairs and installation.
