Replace gas regulator and gas hose – even if they are still working?

Whether on the barbecue, the patio heater or in the caravan: Many people use their LPG system for years – without ever replacing the gas hoses or pressure regulators. After all, everything still works perfectly. But this is precisely where an underestimated risk lies. Legal standards and technical regulations stipulate clear replacement intervals – regardless of the external condition. This article explains why that is and what time limits apply.

Why replace the gas regulator and gas hose – even if they are still working?

Many users rely on the external condition of their LPG system components: the gas regulator shows no signs of wear, the gas hose appears flexible and free from cracks, and the system works perfectly. So why replace anything when everything is functioning flawlessly? The answer is simple: safety.

Gas regulators and hoses undergo a natural ageing process – even if they are rarely used or show no visible damage. Material fatigue, UV radiation, temperature fluctuations and gas pressure all take their toll over time, often only detectable through thorough technical inspection.

This is why rules such as DGUV Regulation 110-010, DIN EN 16129, various DVGW codes of practice and other regulations specify fixed replacement intervals – regardless of condition or frequency of use. This precautionary measure helps prevent dangerous leaks, gas escape or even explosions. Replacement might seem inconvenient, but it is a vital contribution to safety – whether in the garden, when camping, or in commercial use.

Mandatory replacement: What applies to gas regulators and gas hoses

The replacement of pressure regulators and gas hoses is not merely a recommendation – it is clearly regulated in numerous directives. One often-cited standard is DIN EN 16129, which sets out Europe-wide requirements for LPG pressure regulators. However, it does not specify a strict replacement deadline – no direct “replace after ten years” clause. Instead, it issues a recommendation to replace after ten years.

The actual basis for the “10-year rule” for pressure regulators and gas hoses stems from:

• DGUV Regulation 110-010, applicable to commercial use, e.g. in gastronomy, on construction sites or at mobile food stalls

• DVGW Code of Practice G 607, which is binding for LPG systems in recreational vehicles

• DVGW Code of Practice G 608, which governs the operation and inspection of LPG systems on small watercraft – particularly relevant for boats with LPG supply

• DVGW Code of Practice G 612, which concerns portable LPG systems used outdoors in leisure settings – e.g. garden gas barbecues or patio heaters

Only the manufacturing date is relevant, not the date of installation: This is usually found on the type plate of the regulator or printed on the hose, as well as on the yellow hose tags.

If this date is no longer legible or missing, the component should be replaced as a precaution. Also important is the CE marking along with the four-digit notified body number – an indication of compliant manufacturing and testing.

Anyone who adheres to these regulations and manufacturer instructions not only fulfils legal requirements but also actively contributes to greater safety – whether in private or commercial use. Regularly checking the manufacturing date and marking is therefore a simple yet effective safety measure.

How often do gas regulators and gas hoses really need replacing?

The replacement intervals for pressure regulators and gas hoses are either mandatory or recommended depending on the application. These apply regardless of whether the components appear externally intact. The key timeframes are:

• 10 years for pressure regulators – according to manufacturer instructions and supported by regulations such as DGUV Regulation 110-010, DVGW G 607, G 612. This applies to commercial use, caravanning, mobile homes and camping.

• 10 years for hose assemblies – also consistently documented in regulations such as G 612, G 607, TRF and DGUV Regulation 110-010.

The replacement interval always starts from the manufacturing date.

For commercial applications (e.g. gas barbecues in gastronomy, patio heaters at markets, mobile sales units), adherence to the timeframes set out in DGUV Regulation 110-010 is mandatory and verified during inspections.

Special case: Boats and watercraft

While a 10-year replacement interval now applies in most areas, the rules differ for boats, ships, and watercraft. The following intervals apply:

• 6 years for pressure regulators and gas hoses – applies to purely private use of watercraft in accordance with DVGW Code of Practice G 608
• 9 years for pressure regulators – applies to commercial use (e.g. boat hire with a chartered crew) in accordance with DGUV Rule 110-006
• Gas hoses must be replaced at appropriate intervals for commercial use in accordance with DGUV Rule 110-006

Practical examples: When replacement is required

Example 1: Caravanning
LPG systems are common in motorhomes or caravans – for heating, cooking or refrigeration. According to DVGW Code G 607, both pressure regulators and gas hoses must be replaced every ten years. This applies regardless of whether the vehicle is used seasonally or year-round.

Example 2: Barbecuing in the garden or at the campsite
Gas barbecues are often used outdoors for years with the same fittings. However, DVGW G 612 requires replacement of regulators and hoses every ten years, even for private garden use. This helps prevent gas leaks due to ageing from sun exposure and weather.

Example 3: Outdoor heating with LPG
Whether a patio heater at a restaurant or a heater at a Christmas market – extra care is required in commercial use. DGUV Regulation 110-010 mandates replacement of regulators and hoses ten years after manufacture. These deadlines are binding and reflected in inspection principles such as 310-005.

Example 4: Operating a gas hob indoors
Whether in a domestic kitchen or professional restaurant kitchen, the safety requirements are similar. Replacement intervals for pressure regulators and hoses also apply indoors. In private kitchens, replacing these components after ten years is advisable, and for hoses it’s mandatory – based on manufacturer guidance and TRF. In commercial kitchens, DGUV Regulation 110-010 mandates replacement after ten years for both components. Regular leak testing and timely replacement are especially important with frequent use and thermal stress.

Example 5: LPG systems on boats
LPG systems are also widely used in recreational boating – for cooking or heating onboard. What many don’t realise: boats and small watercraft have their own regulations. DVGW Code G 608 requires replacement of regulators and hoses after just six years for private use. This shorter interval accounts for the stress from humidity, temperature fluctuations and increased corrosion. Boat owners should always monitor this timeframe for safety.

What happens if you ignore the replacement intervals?

Ignoring the prescribed intervals for pressure regulators and hoses can lead to far more than just non-compliance:

• Loss of insurance cover: If an accident occurs – such as a gas leak leading to a flash or explosion – and outdated components are found to have been in use, insurers may refuse to pay. This is especially critical in commercial settings.

• Potential safety hazards: As with electricity or water, careless use of LPG can lead to dangerous situations. Old hoses or regulators can become porous or leaky, leading to unnoticed gas leaks. In enclosed spaces, this poses a serious risk of accidents or health issues.

• Inspection failure: During regular gas inspections (e.g. DVGW G 607 in caravans or DGUV checks in commercial use), the condition and functionality of the system are evaluated. Missed deadlines can result in violations, loss of operating licence, or shutdown.

In short: Skipping the replacement not only puts yourself at risk, but also others – and may leave you without legal protection in case of an incident.

Conclusion: Small measure, big impact

Gas regulators and hoses often operate quietly for years – but just like electrical cables or water pipes, LPG systems require vigilance. Knowing and following replacement intervals is an active step toward safety at home, when camping or in business.

Replacing components is technically straightforward, low-cost – yet it can prevent serious dangers. Key regulations such as DGUV 110-010, G 607, G 608 and G 612 provide clear intervals and practical guidance.

Our tip: Regular leak checks, scheduled inspections and tracking the manufacturing date ensure a long-term safe gas supply.
