Gas systems keep your motorhome comfortable, powering everything from your morning coffee to cosy evenings with heating. But these conveniences come with responsibility: without proper care, your gas system can pose serious risks. Regular checks and proper maintenance help prevent accidents, protect your investment, and give you peace of mind on the road.
Whether you drive a compact campervan or a spacious A-Class motorhome, paying attention to your LPG (Liquefied Petroleum Gas) system is essential for safe travels. Our guide highlights key steps and tips for maintaining motorhome gas safety.
Why Does Gas Safety Matter in Motorhomes?
Gas systems in motorhomes work under tougher conditions than static installations. Constant movement, temperature changes, and vibration put strain on connections and components, which increases the risk of leaks. In a confined space, even a small leak becomes dangerous quickly. Carbon monoxide is an added concern. This invisible, odourless gas can build up from faulty appliances or poor ventilation, turning a normal night’s sleep into a serious hazard.
Regular gas safety checks, proper maintenance, and working alarms are your best defence against these risks. They also protect your wallet: many insurers require valid gas certificates before approving claims, so annual servicing becomes a practical necessity.
What Does Your Gas System Include?
Understanding your setup helps you to identify potential problems early. Most motorhomes use propane stored in refillable or exchange cylinders. These connect through regulators and pipes to various appliances.
Your gas system typically powers:
- A cooker and hob for meal preparation
- A heater to keep you warm during cold nights
- A water heater for hot showers
- A fridge when running on gas mode
Each component needs individual attention during gas system maintenance, as problems in one area can affect the entire supply.
What Essential Checks Should You Perform?
Before every trip, spend ten minutes checking your gas supply and connections.
Pre-Journey Inspection
Start by examining your external cylinders and fittings. Look for any signs of damage, corrosion, or loose connections, and make sure the regulator sits firmly and doesn’t move. Replace pigtail hoses every two years, regardless of how they look, as internal deterioration isn’t visible.
Check that the gas valve turns fully on and off without forcing it. A stiff or resistant valve usually indicates an internal fault and needs replacing.
Smell Test
LPG contains an additive that gives it its distinctive smell. If you notice any unusual gas odour while driving or parked, act immediately: turn off the gas at the cylinder, open windows, avoid sparks, and only investigate further once the space is fully ventilated.
Bubble Test for Leaks
Soapy water is an easy and reliable way to detect leaks. Mix washing-up liquid with water, brush it onto the connections while the gas is on, and watch for bubbles. Even small bubbles signal escaping gas and require attention from a Gas Safe-registered engineer.
Never use naked flames to check for leaks – this dangerous practice causes accidents.
When Do You Need a Gas Certificate for Your Motorhome?
Annual servicing by a qualified Gas Safe engineer keeps your system safe and compliant. It’s more than good practice – many insurers require a valid certificate before approving claims.
A proper gas safety check includes:
- Testing and adjusting all gas appliances
- Inspecting pipe connections for leaks
- Checking ventilation grilles for blockages
- Carrying out drop pressure tests to confirm system integrity
- Assessing burner flame patterns
- Verifying carbon monoxide detector functionality
After completing the inspection, your engineer issues a certificate documenting the work. Keep this with your motorhome records, as insurers or future buyers may request it.
Caravans and motorhomes need annual checks, but full-time users or older systems may benefit from more frequent inspections.
How Can You Prevent Carbon Monoxide Poisoning?
Carbon monoxide awareness can genuinely save your life. This dangerous gas forms when appliances burn fuel inefficiently, often because of poor maintenance or blocked ventilation.
Install carbon monoxide alarms in sleeping areas and near gas appliances, and test them monthly using the built-in button. Weak beeps usually mean it’s time for new batteries or a replacement alarm. Most units last five to seven years before their sensors degrade. Keep permanent ventilation grilles clear of bedding, storage, or DIY tweaks so air can circulate properly.
Know the warning signs of carbon monoxide poisoning: headaches, dizziness, nausea, and confusion. If your alarm sounds or you notice any of these symptoms, get outside immediately, switch off the gas at the cylinder, and seek medical help. Quick action makes all the difference.
What Common Gas Problems Should You Watch For?
Experience helps you recognise developing issues before they become emergencies.
The Colour of the Flames
Blue flames indicate complete combustion. This is what you want. Yellow or orange flames mean insufficient oxygen, which can produce carbon monoxide. Have a Gas Safe engineer inspect and adjust appliances showing incorrect flame colour.
Sooty Marks
Black staining around appliances signals incomplete combustion. This demands immediate professional attention before further use.
Pilot Lights Failing
Thermocouples wear out, causing pilot lights to extinguish repeatedly. Replacement fixes this common problem quickly.
