How to Install a Constant Pressure System Like the ESYBOX in Your Home

Low water pressure in showers, kitchens, or bathroom sinks is one of the most common problems in modern homes. If you’re looking for a silent, automatic, efficient solution that keeps constant pressure at all times,
the best option is the DAB ESYBOX 2 HP or ESYBOX MINI constant pressure system.

In this blog, we’ll explain how to install it correctly, what to consider, and how to avoid mistakes that can damage the equipment.

What Is a Constant Pressure System?

A constant pressure system: 

• Detects water consumption
  
• Automatically adjusts motor speed
  
• Maintains stable pressure (no sudden rises or drops)
  
• Saves energy
  
• Operates quietly
  
• Prevents water hammer

DAB’s ESYBOX units are among the best-selling worldwide thanks to their compact design, smart display, and high-efficiency motor.

Materials Needed Before Installation:

• ESYBOX or ESYBOX MINI (according to required flow)
• Check valve (if needed for your installation)
• 2 unions/couplings
• Teflon tape or sealing tape
• 50–100 micron particle filter (recommended)
• A level base for the unit
• Stable electrical connection (110V or 220V depending on model)
• Shut-off valve before and after the unit

Step-by-Step: How to Install an ESYBOX in Your Home

1. Locate the suction and discharge points:

Install the unit close to:

• The main water supply
• The storage tank
• Or the main line feeding the home

Make sure it is placed in a dry, ventilated area protected from direct sunlight.

TIP: Do not install the ESYBOX outdoors without proper protection. The electronics must be shielded from weather exposure.

2. Add a filter before the pump

This prevents sand, dirt, or particles from entering and damaging the impeller.

• Recommended filter: 50–100 microns
• Must be installed before the pump

3. Connect the pipes (suction and discharge)

The ESYBOX includes built-in quick-connection ports. Make sure to:

• Apply Teflon tape correctly
  
• Keep the piping free of obstructions
  
• Avoid tight bends that increase pressure loss
  
• Install a shut-off valve before and after the unit

4. Install the check valve (if required)

In many systems, a check valve is essential to prevent water from flowing back to the tank or supply line.

Place it on the suction line.

5. Verify the electrical connection

• ESYBOX MINI usually runs on 110V
• ESYBOX 1HP/2HP runs on 220V
• A grounded line is required
• Do not use thin extension cords

Tip: Use a voltage protector if you live in an area with unstable electricity.

6. Prime the system if necessary

Although the ESYBOX is self-priming, in some installations it’s recommended to fill the pump before the first startup to prevent cavitation.

7. Turn on the ESYBOX and set the pressure

From the display panel you can adjust the desired pressure. Typical settings:

• 1-story homes → 30 PSI
• 2-story homes → 40 PSI
• 3-story homes → 50–60 PSI

The smart screen allows you to monitor:

• Flow rate
  
• Pressure
  
• Power consumption
  
• Alarm notifications

Common Mistakes You Should Avoid

• Installing the ESYBOX outdoors without protection: Electronics can be damaged by rain and sunlight.
• Not using a filter: Constant pressure systems are sensitive—one grain of sand can cause issues.
• Using pipes that are too narrow: Minimum recommended diameter: 1 inch.
• Setting the pressure to the maximum unnecessarily: This increases energy consumption and reduces lifespan.
• Not grounding the electrical installation: Can cause sensor or electronic board failures.

Conclusion

Installing a constant pressure system like the ESYBOX completely transforms the water experience in your home:

• Strong shower pressure
  
• Stable and consistent flow
  
• Quiet operation
  
• Energy savings
  
• Longer equipment lifespan

If you’re looking for comfort, technology, and zero headaches, this is the best investment your home can have.
