Leak Detection: What Are the Potential Consequences of Leaving a Leak Untreated?

Leaving a leak untreated can have several serious consequences, depending on the type and severity of the leak. Here are some examples of how leaks can affect you, your family and your home:

1. Fatal gas leaks

In England and Wales, around 30 people die every year due to accidental acute CO poisoning, and over 200 people require hospitalisation for non-fatal CO poisoning.  These fatalities and hospitalisations are usually caused by carbon monoxide (CO) leaks from faulty boilers, fires, or other gas appliances. Carbon monoxide is odourless and colourless, so it’s important to install CO detectors in your home.

For more information on symptoms and treatment of carbon monoxide poisoning, please read this information supplied by the NHS: Carbon monoxide poisoning

2. Water damage 

Water damage can weaken the structure of your home by damaging walls, floors, ceilings and even your foundation. The damage also affects the appearance of your home by rotting wood, damaging plaster, and causing paint and plaster to bubble and peel. It also encourages mould and mildew growth that is unsightly and can cause severe health issues. Water damage is also a fire hazard, as it can lead to electrical faults if left unattended.

3. Increased utility bills

If you have a water leak, your water bill may be higher than usual because you’re paying for water that’s going to waste. If you have a leak in your gas line, you can also expect your gas bill to rise significantly. 

4. Health risks

A leak can create a damp environment that promotes mould growth, which can cause respiratory problems and other health issues. In the case of a gas leak, you and your family could be at risk of carbon monoxide poisoning, which can be fatal.

For more information on potential health risks associated with mould, please read the following from the NHS: Can damp and mould affect my health?

5. Safety hazards

If you have a leak in your gas line, it can cause a buildup of gas, which may result in an explosion or fire hazard. Water leaks can create a slip-and-fall hazard, especially for children and older adults, who may not see pools of water collecting around the home.

London Leak Detection: Most Common Leaks and Their Causes

If you own a home, you’re likely familiar with the frustrations that come with leaks. Even minor leaks can lead to major problems, including water damage and increased energy bills. In this section, we’ll explore the most common types of leaks that can occur in a home and their causes, so you can be better equipped to prevent and address leaks as soon as they occur.

What are the most common types of leaks that can occur in a home?

• Leaking pipes: This can happen due to corrosion, damage or wear and tear over time. Water pipes can be hidden behind walls or under floors, so it can be difficult to detect these leaks.
• Leaking taps: These can leak due to worn out washers or damaged components and can waste a significant amount of water over time.
• Leaking toilets: This can occur when the toilet is not sealed properly or if the flush valve or flapper is not working properly.
• Leaking boilers: Water heaters can leak due to a variety of reasons, such as corrosion, high water pressure, or a malfunctioning valve.
• Leaking washing machines or dishwashers: These can leak due to damaged hoses or connections, or if they move around slightly during use, this can place strain on the pipes and hoses, leading to cracks and breaks.
• Central heating leaks: Wear and tear, installation issues and corrosion are all common causes of leaks in your central heating system.

It’s important to be aware of the risks that come with undetected leaks in your home and take measures to prevent them before they cause more serious problems. Taking the time to inspect pipes regularly and ensure they are properly maintained can help you catch any potential issues before they need costly repairs or professional leak detection services.

What causes leaks in your home?

• Age and wear and tear: Plumbing components such as pipes, taps, and water heaters can wear out over time, leading to leaks.
• High water pressure: If the water pressure in a home is too high, it can put stress on pipes and other components, causing leaks.
• Poor installation: If plumbing components are not installed properly, they can be more prone to leaks.
• Extreme weather conditions: Cold temperatures can cause pipes to freeze and burst, while heavy rainfall can overwhelm drainage systems and cause leaks.
• Chemical damage: Chemicals such as limescale can build up in pipes over time, causing corrosion and leaks.

5 DIY Leak Detection Tips: How to Find Leaks & When to Call a Professional

1. Perform a manual inspection leak detection around your home

Checking your home for leaks on a regular basis can prevent inflated water bills and costly repairs. However, some leaks occur below ground and cannot be detected without the assistance of professional leak detection methods. While plumbing leaks detection and repair are typically best left to leak detection specialists, there are a few things to look out for during a manual inspection of your home:

• See if you can hear any dripping or running after when water is not in use
• Check for leaking or dripping taps
• Look under sinks for pools of water, especially if the sink is above or mounted into cabinets in your bathrooms and kitchen
• Walk around your home and feel the floors and walls for any hot or warm spots
• Mould, mildew or rising damp present in rooms other than the bathroom 
• Inspect walls and floors for sponginess

All of the above signs indicate that you may have a leak, and we recommend calling a leak detection company immediately before the leak leads to costly damage and repairs.

2. Keep an eye on your gas and water bill

Comparing your water and gas bills over the last 6 months can help you get an idea of your monthly usage. If you notice that your monthly usage has increased exponentially, then you may have a leak. Depending on which bill has increased, perform a manual inspection of that area and see if you notice any signs of a leak. In order to save money in the long run and have peace of mind that your family is safe, we recommend calling a professional plumber to conduct a leak detection.

3. How to check for a leak in your central heating unit

Checking your central heating system regularly is an essential part of home maintenance. DIY leak detection can be tricky, but here are a few steps you can take to see if you have a leak: 

• Check the pressure: If the pressure in your system is low, under 1.5 bar, this can indicate a leak.
• Look for visible signs: Check the pipes, valves, radiators, and other parts of the system for any signs of moisture, rust, or discolouration.
• Check the boiler: Look for any water escaping from your boiler, and check the drip tray underneath it for any signs of leakage.
• Listen for unusual sounds: Any hissing or whistling sounds coming from your central heating are an indication that you have a leak present.
• Reduced heat: A leak can cause less hot water to circulate, leading to reduced heat in your home.
• High utility bills: A central heating leak can cause your bills to increase due to water and energy wastage.

4. Leak detection for your toilet

As we mentioned above, toilet leaks are the most common leak fixed by plumbers in the UK, so it is important to check your toilet regularly for leaks. The easiest way to do this is through a dye test, and here’s how to perform one: 

1. Ensure the toilet has been flushed after the last person used it, and wait for the reservoir tank to refill. The water must be clear.
2. Add a few drops of food colouring to the water in the cistern (toilet water reservoir) in order to stain the water a darker colour.
3. Do not use or flush the toilet for 30 minutes and ensure family members know you are performing a test.
4. Check the colour of the water in the toilet bowl after at least 30 minutes.
5. If the colour of the water has changed in the toilet bowl, it could indicate a leak originating from the cistern.

The test cannot detect a leak behind the toilet, but regularly checking for standing water in the vicinity can assist in identifying a sewage line leak.

5. How to detect a gas leak

As we mentioned above, gas leaks must be taken seriously and dealt with immediately as they are dangerous and potentially fatal. Here are 5 ways to tell if you have a gas leak:

1. You can smell rotten eggs (sulphur): Many gas manufacturers now place an additive called mercaptan into gas to help you identify a leak in your gas line before it becomes dangerous.
2. Hissing or whistling sounds: Listen out for any strange noises coming from your gas lines, as gas escaping under high pressure will emit a hissing or whistling sound.
3. Check your gas stove top: If your stove uses gas, check that the flame burns blue when it’s turned on. If the flame is red/orange, it may be a sign that there is excess gas in the air.
4. Water and dish soap test: To check for a gas leak, combine 5mls of washing up liquid with a cup of water. Place the solution in a spray bottle and spray the liquid onto the area of your gas line where you think there may be a leak. If you notice the formation of bubbles, it confirms the presence of a gas leak.
5. Gas leak detector spray: As an alternative to the soap test, you can purchase a convenient leak detector spray. You simply spray joints and pipes with the spray, and if there is a leak present, the spray will emit large soap-like bubbles.

If you suspect a gas leak, it is critical that you call a plumber to perform specialist leak detection and leak repair services to ensure your safety. If you cannot get hold of a professional, please call the National Gas Emergency Service on 0800 111 999; help is available 24/7.

Will a Carbon Monoxide Detector Detect a Gas Leak? 

In technical terms, a carbon monoxide detector is specifically designed to identify elevated levels of carbon monoxide in the air, which could result from toxic gases, combustion, or air quality issues. Although often associated with gas leaks, carbon monoxide detectors are not designed to detect the presence of gas itself.

How Much Does Leak Detection Cost in the UK?

The cost of leak detection services in the UK can vary depending on several factors, such as the location and severity of the leak, the type of property, and the leak detection equipment required. The cost can also increase significantly if the leak is difficult to locate or if extensive repairs are required. It’s best to get a quote from a professional plumbing company to get a better idea of the costs involved with your specific situation.
