Safe gas system in motorhomes: 6 common mistakes – and how to avoid them

Whether you’re heading off on a grand tour or taking a quick weekend trip, liquefied petroleum gas (LPG) in motorhomes offers comfort but also involves risks if used improperly. Many campers underestimate typical vulnerabilities – such as outdated gas pressure regulators, hoses without visible manufacturing dates, missing gas filters, or insufficient ventilation. In this article, we highlight the six most common safety gaps – and how you can easily avoid them. With practical tips, legal advice on the G 607 gas inspection, and product recommendations for greater safety on the road.

Camping & Caravanning represents freedom, independence, and the feeling of being at home while on the move. LPG enables many conveniences – from heating to cooking. At the same time, operating the gas system safely requires a certain level of care. In practice, however, it quickly becomes apparent that negligence can easily creep in during everyday use. This article helps you identify and deliberately avoid common mistakes – for greater safety at every stage of your journey.

Mistake 1: missing or overdue gas inspection (G 607)

The G 607 gas inspection is one of the most important safety measures in the field of caravanning – yet many campers neglect it. Regular inspections are not only legally required, but also essential for the safe operation of your gas system. Especially in older vehicles, leaks, brittle hoses, or defective regulators can go unnoticed – with potentially serious consequences.

Since the revision of the G 607 inspection regulations – which we covered in detail in the article “Gas Inspection for Caravans and Motorhomes: What Is G 607?” – one thing is clear: Anyone travelling with a motorhome or caravan should have their gas system regularly checked by a certified expert – regardless of whether an inspection sticker is present. The G 607 inspection not only detects leaks but also ensures that all components function correctly and meet safety requirements.

Another important point: many campsite operators require proof of a valid gas inspection before allocating pitches. A missing or outdated inspection can therefore not only pose a risk to you and your fellow travellers but may also disrupt your travel plans. Our recommendation: Have your gas system inspected at least every two years – and again after any technical modifications or extended periods of disuse.

Mistake 2: using unsuitable or outdated gas pressure regulators

A functioning gas pressure regulator is the heart of every LPG system in a motorhome. It reduces the cylinder pressure to a safe level, thereby ensuring the reliable operation of cookers, heaters, and refrigerators. However, many campers overlook the fact that this inconspicuous component is also subject to natural ageing.

In Germany, the DVGW worksheet G 607 (A) stipulates that gas pressure regulators, automatic changeover devices, and hose assemblies must be replaced no later than ten years after their manufacturing date – regardless of whether they are still working or how frequently they have been used. This deadline is based on the manufacturing date stated on the type plate, not the date of installation.

An overaged regulator may lose its functionality, potentially leading to hazardous situations such as gas leaks, excessive gas pressure, or uncontrolled gas discharge. Furthermore, passing the gas inspection is not possible without timely replacement of these components.

Tips for travelling in europe

A look at other European countries reveals that regulations vary:

• Austria: Guideline G 107 also recommends replacing regulators and hoses after ten years. However, gas inspections are not mandatory, although they may be required as part of the §57a vehicle inspection.

• France: Regular gas inspections are not mandatory. However, a technical approval of the gas system may be required when registering imported vehicles.

• United Kingdom (UK): No legally mandated replacement intervals exist. Nevertheless, it is recommended to replace gas pressure regulators and hoses every ten years to ensure safety.

• Netherlands and Italy: No known statutory replacement intervals. Nonetheless, regular checks and replacements as needed are generally advised.

• Switzerland: LPG installations in motorhomes, caravans, and awnings must be inspected every three years by a qualified professional in accordance with EKAS guideline no. 6517. The inspector regulations assume a service life of 10 years for pressure regulators and hoses.

For campers who frequently travel across various European countries, it is advisable to adhere to the strictest national regulations – in this case, the German ones. This way, you are on the safe side and can avoid potential issues during gas inspections or technical approvals abroad.

A practical tip: Modern gas pressure regulators, such as the Caramatic DriveOne or DriveTwo as well as the Caramatic SafeDrive and SafeDrive PLUS from GOK, come equipped with integrated safety features like crash sensors and are approved for use while driving. These models not only enhance safety but also make it easier to comply with replacement intervals thanks to clearly marked manufacturing dates.

Mistake 3: no gas filter? system contamination!

An often underestimated yet safety-critical aspect of operating gas systems in motorhomes is the absence of a gas filter. LPG may contain oily residues, dirt particles, and aerosols, which can enter the system with the gas flow. These contaminants settle in the delicate components of regulators, changeover devices, and valves, where they can cause damage – and in the worst-case scenario, prevent the gas appliances from functioning properly.

A malfunctioning regulator not only affects the overall performance of the gas system but can even lead to complete system failure. The solution is both simple and effective: a gas filter. For wall-mounted gas pressure regulation systems like the Caramatic DriveOne or DriveTwo, GOK specifically recommends the use of the Caramatic ConnectClean gas filter. Installation is straightforward, and the filter can be retrofitted into any existing wall-mounted regulator system thanks to its standardised connections.

Particularly Sensible using a gas filter is especially advisable when using exchangeable gas cylinders, as the purity of the gas cannot always be guaranteed. Travellers using their motorhome abroad should also bear in mind that gas quality often differs from country to country – significantly increasing the risk of contamination.

A gas filter, combined with regular maintenance, not only protects the technology but can also save you money in the long run: thanks to a lower risk of system failure and a longer service life.

Mistake 4: operating the system while driving without a safety device

Many campers wish to use their gas system while driving – for example, to run the fridge. While this may sound practical, it can quickly become dangerous if there is no suitable safety device installed. In the event of a vehicle accident, there is a serious risk that damage to a hose or pipe could lead to uncontrolled gas leakage – with potentially life-threatening consequences.

To ensure safe operation of the gas system while the vehicle is in motion, legal regulations require the presence of appropriate safety devices. Chief among these is a crash sensor, which automatically shuts off the gas supply in the event of an impact.

GOK offers modern gas pressure regulation systems with integrated crash sensors through products like the Caramatic DriveOne, Caramatic DriveTwo, and Caramatic SafeDrive. These systems reliably shut off the gas supply in the event of an accident – allowing safe continued operation while driving.

Important to know: for the DriveOne and DriveTwo models, an excess flow valve is additionally required. Only in combination with this valve does the system fully meet the legal safety requirements for operation while the vehicle is in motion. The excess flow valve prevents uncontrolled escape of unburned LPG in case of hose rupture or significant leakage.

Mistake 5: incorrect installation or DIY modifications

Many campers wish to expand, convert, or repair their gas system themselves – whether to save costs or implement custom solutions. However, when it comes to LPG systems, the utmost care is essential. Improper installation can lead to severe safety risks, such as leaking connections, incorrect component selection, or incompatible gas pressures.

Therefore, the rule is: installation of gas pressure regulators, changeover devices, filters, or safety components should always be carried out by a trained professional workshop. These experts have the necessary technical knowledge and equipment to ensure that installations are performed safely, reliably, and in accordance with relevant standards.

A particularly important note from GOK: Always observe the installation and operating instructions for each product. These are included with every product and are also available in the Download Centre at www.gok.de. There, you will also find detailed information on installation guidelines, connection configurations, inspection notes, and maintenance recommendations. Installation errors not only pose safety risks but may also affect your warranty claims against the manufacturer.

If you want to be on the safe side, have all modifications to the gas system carried out exclusively by a qualified workshop – for safe operation and carefree travel enjoyment.

 

Mistake 6: No Emergency Plan – and No Training in Gas Handling

No matter how reliable modern gas systems may be, no one is immune to malfunctions or unexpected situations. That makes it all the more important to know how to react quickly and correctly in an emergency. Yet many campers do not know what to do in the event of a gas leak, unusual gas smell, or even a fire. They lack a basic emergency plan – and the knowledge of essential safety procedures.

Simple measures can already make a big difference to safety: every traveller should know where the individual shut-off devices for gas appliances or the main shut-off valve for LPG are located – and how to operate them. In a conventional gas cylinder system, the main shut-off valve corresponds to the cylinder valve. Campers should also refresh their knowledge on what to do in case of gas smell: immediately ventilate the area, eliminate all ignition sources (e.g. do not use electrical switches), and close the shut-off valves. A small emergency checklist inside the vehicle can save valuable seconds when it counts.

It is also advisable to familiarise yourself with the operation of your gas system before travelling – ideally by consulting the operating instructions that GOK provides with all its products. These are available online in the Download Centre at www.gok.de. Additionally, many specialist workshops offer hands-on briefings – an investment that can pay off in an emergency.
