What To Do If Your Boiler Is Leaking?

If your boiler has developed a water, gas, or carbon monoxide leak, it is a clear sign of a major problem. It’s important to take action as soon as possible, as the leak may cause damage or endanger the property’s occupants. But what steps should you take?

In this guide, I am going to identify the common causes of boiler leaks and offer a step by step process for dealing with each type of leak. If you require any further assistance, give Quantum Gas Engineering a call on 0203 633 6322.

Is A Leaking Boiler Dangerous?

A gas leak or carbon monoxide leak can be extremely hazardous to building occupants. If you believe you are dealing with this type of leak, you will need to obtain help immediately and evacuate the building. However, there are some steps that should be taken before leaving, which are explained below.

Water leaks are usually less dangerous but can cause significant damage to a property in a surprisingly short period of time. However, they may be dangerous when water from a leak comes in contact with electrical appliances or electrical outlets. Contact a professional immediately if you are dealing with a large amount of water leakage.

Common Causes Of Leaking Boilers

Before a leaking boiler can be fixed, the root cause of the problem must be identified. Here are a few of the common causes of leaks:

Corrosion
If a pipe has been corroded, it may cause a water or gas leak, depending on the type of pipe affected. If the corrosion is on a single pipe or valve, it is usually a straightforward repair. The affected component is simply removed and replaced. If the corrosion affects several components within the boiler, it is usually cheaper to replace the boiler rather than attempt to patch it up.

Temperature valve
The boiler temperature valve is designed to control output water temperature, preventing scalding hot water being sent directly to taps. If there is a fault with the temperature sensors in the boiler, it may lead to the boiler overheating which may cause a water leak near the temperature valve.

Pressure valve
The boiler’s pressure relief valve is a safety mechanism that prevents the pressure in the boiler from getting too high. If there is a buildup of limescale and other debris, this valve can become blocked, causing a water leak.

Pump seals
If you boiler’s water pump is malfunctioning, it can cause a water leak. The pump will probably need to be replaced if this occurs.

Defective appliance or improper installation
Water, gas, and carbon monoxide leaks can all be caused by a boiler being improperly installed, configured incorrectly, or suffering a catastrophic failure. This is why it is important to always purchase high-quality appliances which are installed by a Gas Safe Engineer.

Poor ventilation
Boilers produce a small amount of carbon monoxide during operation. This poisonous gas is usually exhausted from your home via a flue. However, if this flue becomes blocked, it can cause carbon monoxide to leak into your property.

Your carbon monoxide detector should alert you to a buildup of this gas. However, if your detector isn’t working correctly, you may also experience symptoms like headache, sickness, dizziness, fatigue, stomach pain, difficulty breathing and confusion. Carbon monoxide is extremely dangerous, so action should be taken to address this type of leak immediately.

What To Do When A Boiler Leak Occurs

Gas Leaks
A gas leak is a serious and potentially life threatening problem which needs to be acted upon immediately. If you smell gas in your home:

1. Evacuate children, the elderly, and pets from the building
Reduce the number building occupants immediately by evacuating any person or animal who doesn’t need to be there.
2. Call for help (walk outside if using a mobile phone)
Call the National Gas Emergency Helpline on 0800 111 999 to report a gas leak. They will immediately call for a Gas Safe Engineer to visit your home and notify authorities. Alternately, you can call the emergency hotline of a local business with Gas Safe Engineers, like Quantum as Engineering (phone 0203 633 6322). Make this call on a landline or walk outside to use your mobile phone to avoid a spark being created.
3. Avoid any actions which may ignite gas
As you walk around your home, avoid any actions like using light switches, turning computers on, or lighting a match.
4. Open all doors and windows
Opening up your house will help the gas escape before it can build up to dangerous levels.
5. Switch off your gas supply
There will be a valve on the incoming gas line that can be turned to stop gas flow. Locate this valve and turn it off.
6. Evacuate yourself
It’s safer to wait outside until help arrives.
7. Seek out medical attention
If you are feeling unwell, see a doctor.

A Gas Safe Engineer will be required to address the problem cause your gas leak. Give Quantum Gas engineering a call to get the repair started.

Carbon monoxide leaks
If your carbon monoxide alarm goes off or you notice the symptoms of carbon monoxide poisoning (headache, sickness, dizziness, fatigue, stomach pain, difficulty breathing and confusion), follow these steps:

1. Evacuate children, the elderly, and pets from the building
Reduce the number of people and animals in the building immediately.
2. Open all doors and windows
Opening up your house will help the carbon monoxide escape.
3. Switch off your gas appliance
Turn off your boiler or the gas supply.
4. Evacuate yourself
Leave the property and stay outside until help arrives.
5. Call for help (walk outside if using a mobile phone)
Call the National Gas Emergency Helpline on 0800 111 999 to report a carbon monoxide leak. You can also call Quantum as Engineering on 0203 633 6322
6. Seek out medical attention
If you are feeling unwell or experiencing the symptoms of carbon monoxide poisoning, see a doctor.

Water Leaks
If you notice that your boiler has begun to leak water, here’s what to do:

1. Make sure the water isn’t in contact with electrical appliances or outlets
If you have a large amount of water on the ground, perform a visual inspection to determine if it is in contact with anything electrical. If you are unsure, turns the electrical mains off while you get a closer look.
2. Turn off electricity to the boiler
If you have a modern boiler, it will use electricity. You should turn this off as an additional safety measure. Look in the main box for the switch labeled “Boiler” or “Heating system” and turn it off.
3. Place a bucket, bowl, or towel beneath the leak
If you have a small leak, this should be sufficient to collect water before it damages your property
4. Identify where the leak is coming from
See if you can determine where the leak is coming from. If it is obviously coming from the temperature gauge or pressure relief valve, then you already know the cause.
5. Perform the repairs
If you are a handyman, you may be able to tackle minor issues like a corroded valve or pipe. If you don’t have the time or the necessary skills, give Quantum Gas Engineering a call on 0203 633 6322.
