What is water pressure?
Water pressure is a fundamental aspect of any plumbing system, determining the force with which water flows through pipes and exit fixtures. It's generated by a combination of gravity and pumps, with the primary source often being elevated water towers or reservoirs. The pressure is influenced by several factors:
Height of the water source: The higher the source, the greater the natural pressure.
- Distance from the source: Pressure tends to decrease as water travels further.
- Pipe size and material: Smaller pipes and certain materials can restrict flow, affecting pressure.
- Demand on the system: Peak usage times can lead to pressure drops.

How to Measure Water Pressure
Accurate measurement is crucial for diagnosing and resolving pressure issues. The most reliable method involves using a pressure gauge:
- Locate an outdoor tap or washing machine connection.
- Ensure no water is being used in the property.
- Attach the pressure gauge to the chosen outlet.
- Turn on the water and read the gauge.
Pressure is typically measured in pounds per square inch (psi) or bar. One bar equals approximately 14.5 psi.
Ideal Water Pressure Levels
For residential properties, the ideal water pressure range is generally between 40-60 psi (2.75-4.14 bar). However, specific fixtures may have different requirements:
- Showers: 10-50 psi (0.69-3.45 bar)
- Toilets: 20-30 psi (1.38-2.07 bar)
- Washing machines: 20-40 psi (1.38-2.76 bar)
Pressure below 40 psi may result in weak flow, while pressure above 60 psi can strain pipes and appliances.
How to Increase Water Pressure
Several methods can be employed to boost low water pressure:
- Install a water pump or booster pump: These devices actively increase pressure within the system.
- Upgrade pipes: Larger diameter pipes can improve flow and pressure.
- Fix leaks and clogs: Address any blockages or leaks that may be reducing pressure.
- Adjust or replace the pressure regulator: Ensure it's set correctly or replace if faulty.
How to Decrease Water Pressure
When pressure is too high, consider these solutions:
- Install a pressure-reducing valve: This device automatically lowers incoming water pressure.
- Use flow restrictors: These can be fitted to individual taps or showerheads.
- Adjust the pressure regulator: If present, it can be tuned to lower the overall system pressure.
Understanding Different Heating Systems and Pressure
Gravity Fed Systems
These low-pressure systems use a cold water storage tank and a hot water cylinder. Pressure depends on the height difference between your storage tank and taps - meaning upstairs taps typically have lower pressure than downstairs. Installing a pump can significantly improve pressure and expand your tap options.
Combi-Boilers
These systems heat water directly from the mains supply, providing high-pressure hot water on demand. Modern combi-boilers include pressure gauges for easy monitoring and typically deliver excellent flow rates throughout your property.
Unvented Systems
Offering the highest pressure options, these systems fill directly from mains water and maintain pressure through the incoming supply. Water heats through various sources including boilers, solar panels, oil, or electricity.
