Booster Pumps Explained: How to Improve Water Pressure at Home & Work
Low water pressure is a common and frustrating problem in homes, workshops, commercial premises and agricultural settings. Whether it’s a weak shower, slow-filling tanks, or inconsistent flow to taps and equipment, poor water pressure can significantly affect daily operations.
In this guide, we explain what booster pumps are, how they work, and how to choose the right booster pump to improve water pressure both at home and at work.
What is a Booster Pump?
A booster pump is a compact water pump designed to increase water pressure and flow rate within a plumbing system. It works by drawing water from an existing supply – such as a mains line, storage tank, or rainwater system – and boosting the pressure before delivering it to taps, showers, irrigation systems or equipment.
Booster pumps are commonly used where:
- Mains water pressure is too low
- Gravity-fed systems struggle to supply consistent flow
- Multiple outlets are used simultaneously
- Equipment requires stable water pressure
Common Causes of Low Water Pressure
Before choosing a booster pump, it’s helpful to understand why water pressure may be low:
- Distance from the mains supply
- Aging or narrow pipework
- Multiple outlets in use at the same time
- Gravity-fed water systems
- Water storage tanks located below outlets
In many cases, installing a water booster pump is the most effective and cost-efficient solution.
How Booster Pumps Improve Water Pressure
Booster pumps work by:
- Detecting demand when a tap or outlet is opened
- Automatically switching on
- Increasing water pressure and flow
- Switching off once demand stops
Most modern booster pumps feature automatic pressure control, meaning they only run when water is required. This improves efficiency, reduces wear, and helps protect the pump from dry running.
Types of Booster Pumps Explained
1. Domestic Booster Pumps
Designed for homes and small properties, these pumps are ideal for:
- Improving shower pressure
- Boosting taps and household plumbing
- Supplying water from storage tanks
They are typically compact, quiet, and easy to install.
2. Commercial & Workshop Booster Pumps
Used in:
- Workshops and garages
- Light commercial buildings
- Washdown systems and plant rooms
These pumps offer higher flow rates and greater durability for more demanding use.
3. Irrigation & Water Transfer Booster Pumps
Suitable for:
Garden irrigation systems
Greenhouses and allotments
Water transfer from tanks and rainwater harvesting systems
They provide consistent pressure over longer distances and multiple outlets.
Which Booster Pump Do I Need?
| Application | Recommended Booster Pump | Flow / Head | Best For |
|---|---|---|---|
| Weak shower & tap pressure | Clarke BPT600 1″ 600W Booster Pump | ~50 L/min / 35 m | Homes with low mains pressure |
| Higher demand domestic use | Clarke BPT1200SS 1″ 1200W Booster Pump | ~61 L/min / 46 m | Larger homes & multiple outlets |
| Garage & workshop water supply | Clarke CBT1300SS 1″ 1350W Stainless Steel Booster Pump | ~90 L/min / 35 m | Workshops & frequent use |
| Professional & higher flow | Clarke CBT1400SS 1″ 1650W Stainless Steel Booster Pump | ~90 L/min / 50 m | Commercial sites & heavy usage |
Key Specifications to Consider When Choosing a Booster Pump
When selecting a booster pump, it’s important to consider the following:
Flow Rate (L/min)
Indicates how much water the pump can move. Higher flow rates are needed when supplying multiple outlets.
Head Height (m)
Represents how high, in metres, the pump can push water vertically. This also correlates with pressure capability.
Power Rating (W)
Higher wattage generally means more power and performance, but should be matched to your application.
Inlet & Outlet Size
Ensure compatibility with your existing pipework (commonly 1″ BSP).
Water Type
Most booster pumps are designed for clean water only. Always check suitability.
Where Booster Pumps Are Commonly Used
Booster pumps are widely used across many environments, including:
- Homes with poor mains pressure
- Bathrooms and showers
- Garden irrigation systems
- Workshops and garages
- Small commercial buildings
- Agricultural and water storage setups
Are Booster Pumps Energy Efficient?
Yes – modern booster pumps are designed for efficiency. Automatic pressure control ensures the pump only runs when needed, helping to reduce energy consumption and operating costs.
Choosing the correctly sized pump for your application is key to maximising efficiency.
