How to Choose a Surface Domestic Water Pump? Overview of Wilo Solutions for Every Home

Choosing a domestic water pump is not just about the brand or performance. Every house, well, or operation has different needs – and the Wilo brand offers more than just one universal solution. In this article, we will show you four different ways to assemble or choose a Wilo domestic water pump exactly according to your preferences.

Not sure if you need a tank, frequency converter, or submersible pump? We will advise you.

1. Classic Wilo HWJ Water Pump – with Bladder or Membrane

The Wilo HWJ series represents a proven choice for anyone looking for a traditional domestic water pump with a pressure tank.

You can choose:

• Version with a replaceable bladder – lower price, easy maintenance
• Version with a fixed membrane – less demanding on service, ideal for smaller properties, 5-year warranty

Suitable for:

• Family homes, recreational properties, smaller businesses
• Applications with constant water consumption (shower, toilet, washing machine, kitchen)

Advantages:

• Stable pressure thanks to the tank (24–60 l)
• Protection against "dry running" activation
• Possibility to add protective and regulatory elements
• Certified for drinking water

3. Build Your Own Water Pump – Custom Wilo Solutions

Do you have specific requirements or want to have everything under control? Then there is the option of your own assembly from individual Wilo components.

What you can combine:

• Wilo WJ pump
• Pressure switch or flow control unit
• Expansion tank with suitable volume
• Frequency converter for speed control and constant pressure
• RCL fitting – for easy connection and system protection
• Pressure gauge
• Pressure hose

Suitable for:

• Technically skilled users
• Operations with variable consumption
• Specific projects (e.g., gardening, guesthouses)

Custom assembly allows you to precisely adjust performance, pressure, and control according to actual conditions – ideal for atypical wells, multiple distribution branches, or a house + garden combination.

4. Submersible Domestic Water Pump Wilo – When the Well is Deep or Far

If the water level is deeper than 8 meters, or the well is more than 20 meters away from the house, it is more suitable to choose a submersible pump. Wilo offers two highly reliable variants.

Recommended models:

• Wilo Sub TWI 5 – versatile 5" pump with quiet operation and high lift
• Wilo Extract FIRST – robust solution for tanks and wells with integrated protection

Both recommended models are certified for contact with drinking water.

Recommended accessories:

• Expansion tank for pressure stabilization
• Flow switch or frequency converter depending on the application
• Dry run protection

Suitable for:

• Drilled wells (e.g., 30–60 m deep), deep dug wells
• Supplying water to the house and garden over a longer distance
• Quiet operation, no vibrations, no suction height limitation

These solutions are also ideal where it is not possible to install a pump at the well – for example, due to noise, frost protection, or lack of space.

Conclusion: Choose a Water Pump that Fits Your Home and Style

A domestic water pump should not be a compromise. Whether you prefer the classic with a pressure tank, smart control with constant pressure, or like to assemble the system yourself, Wilo offers an answer for every type of household and every technical assignment.
