Boiler Pressure Too High – Plumber Totterdown Will Tell You Why and How to Reduce It

Are you experiencing high boiler pressure in your home? If so, it’s important to address this issue promptly to prevent potential damage to your boiler system. In this article, we will delve into the reasons behind high boiler pressure and provide you with effective solutions to reduce it. Our expert plumbers in Totterdown are here to guide you through the process and help you maintain a safe and efficient boiler system.


Boiler pressure is a crucial aspect of your heating system’s operation. It refers to the force exerted by the water within your boiler, which is essential for providing hot water and heating throughout your home. However, when the pressure becomes too high, it can lead to various issues and compromise the safety and efficiency of your boiler.

2. Understanding Boiler Pressure

Boiler pressure is measured in units of bar, with the ideal pressure range typically between 1 and 1.5 bar. If the pressure exceeds this range, it is considered high and requires immediate attention. High boiler pressure can put excessive strain on the various components of your boiler system, leading to potential failures if not addressed promptly.

3. Causes of High Boiler Pressure

Several factors can contribute to high boiler pressure. Let’s explore some common culprits:

Water Filling Loop Issue

A malfunctioning water filling loop can cause continuous water supply to the boiler, leading to an increase in pressure. This issue often occurs when the filling loop valve fails to close properly, allowing water to enter the system excessively.

Faulty Pressure Relief Valve

The pressure relief valve is designed to release water from the boiler when the pressure exceeds the recommended level. If the valve becomes faulty or fails to operate correctly, it can result in a buildup of pressure within the system.

Expansion Vessel Problems

The expansion vessel is responsible for absorbing the excess pressure generated as water heats up within the boiler. If the vessel loses its functionality due to a faulty diaphragm or an incorrect pressure setting, it can contribute to high boiler pressure.

Issues with the Boiler Pump

A malfunctioning boiler pump can disrupt the circulation of water, leading to pressure buildup. This problem often occurs when the pump is clogged, damaged, or not operating at the correct speed.

4. Signs of High Boiler Pressure

Detecting high boiler pressure is crucial for timely intervention. Here are some common signs to look out for:

Leaking Pressure Relief Valve

If you notice water dripping from the pressure relief valve, it is a clear indication of high pressure within the boiler system.

Strange Noises Coming from the Boiler

Unusual noises, such as banging or hissing sounds, can occur when the pressure is too high. These noises often indicate that the system is struggling to cope with the excessive pressure.

High Pressure Reading on the Gauge

Most boilers have a pressure gauge that displays the current pressure reading. If the gauge shows a significantly higher value than the recommended range, it suggests high boiler pressure.

Radiators Not Heating Up Properly

When the pressure is too high, it can affect the proper functioning of your radiators. If you notice cold spots or inconsistent heating across your radiators, it may be a result of high boiler pressure.

5. Potential Risks of High Boiler Pressure

Allowing high boiler pressure to persist can lead to various risks, including:

Boiler Damage

The excessive pressure can put a strain on the boiler’s components, potentially causing leaks, valve failures, or even complete breakdowns. Repairing or replacing a damaged boiler can be costly and inconvenient.

Safety Concerns

High boiler pressure poses safety risks, as it increases the likelihood of leaks, pipe bursts, or even explosions. These incidents can lead to property damage and pose a threat to the occupants’ well-being.

6. How to Reduce Boiler Pressure

Now that we understand the causes and risks of high boiler pressure, let’s explore some effective methods to reduce it:

Bleeding Radiators

Bleeding your radiators is a simple yet effective way to release trapped air within the system, which can contribute to high pressure. By using a radiator key to open the bleed valve, you can release the excess air and subsequently reduce the pressure.

Adjusting the Pressure Relief Valve

If the pressure relief valve is faulty, it may need adjustment or replacement. Consult a professional plumber to inspect the valve and make the necessary adjustments to ensure it operates correctly.

Checking the Filling Loop

Inspect the water filling loop to ensure it is functioning properly. If you notice any leaks or abnormalities, contact a qualified plumber to repair or replace the faulty components.

Inspecting the Expansion Vessel

A malfunctioning expansion vessel can be a common cause of high boiler pressure. A professional plumber can check the vessel’s pressure and, if needed, adjust or replace it to restore the system’s balance.

Checking the Boiler Pump

A malfunctioning boiler pump can disrupt water circulation and contribute to pressure buildup. A qualified plumber can inspect the pump, clean or repair it, or recommend a replacement if necessary.

7. Maintenance Tips for Optimal Boiler Performance

To maintain a safe and efficient boiler system, consider the following maintenance tips:

Regular Servicing

Schedule regular boiler servicing with a qualified plumber to ensure its optimal performance. Routine maintenance can identify and address potential issues before they escalate into major problems.

Proper Insulation

Properly insulating your pipes and boiler can prevent heat loss and improve energy efficiency. It also helps maintain stable pressure levels within the system.

Avoiding Overuse

Professional plumbers Lodgehill can identify the source of leaks and repair or replace the faulty components, saving water and preventing further issues. Avoid excessive use of hot water and heating to prevent unnecessary strain on your boiler. Using your system responsibly can help regulate pressure levels and extend its lifespan.

8. Conclusion

High boiler pressure is a common problem that can lead to significant issues if left unattended. By understanding the causes, signs, and risks associated with high pressure, you can take appropriate measures to address and reduce it. Regular maintenance and timely intervention are essential for ensuring a safe, efficient, and long-lasting boiler system.

9. FAQs (Frequently Asked Questions)

1. What should I do if my boiler pressure is too high?

If your boiler pressure is too high, you should try bleeding your radiators to release excess air. If that doesn’t work, contact a professional plumber to inspect and address the issue. Contact several plumbers and request detailed quotes for the work you need.

2. Can I reduce boiler pressure on my own, or should I call a professional plumber?

Ensure that the Bristol plumber you hire is licensed and insured. While bleeding radiators is a simple task that you can do on your own, addressing other causes of high boiler pressure may require the expertise of a professional plumber.

3. How often should I have my boiler serviced?

It is recommended to have your boiler serviced annually by a qualified plumber. Regular servicing helps identify and resolve potential issues before they worsen.

4. Are there any long-term solutions to prevent high boiler pressure?

Proper maintenance, including regular servicing and inspections, can help prevent high boiler pressure. Additionally, installing a pressure reducing valve can regulate the pressure and protect your system.

5. Is high boiler pressure dangerous?

Yes, high boiler pressure can be dangerous. It can lead to leaks, pipe bursts, or even explosions, posing safety risks and potential property damage.

Remember, addressing high boiler pressure promptly and following proper maintenance practices will ensure the safety, efficiency, and longevity of your boiler system. Don’t hesitate to reach out to our expert plumbers in Totterdown for professional assistance and guidance.
