Nedgia Gas Inspection Anomalies: How to Resolve Main and Secondary Defects Before Supply Cut
Every 5 years, the natural gas distribution network (in most of Catalonia, Nedgia from Naturgy Group) is legally required to conduct a periodic safety inspection of individual installations. If the inspector spots a technical flaw or gas leak, they do not repair it: they issue an official inspection report and establish a strict correction deadline. Serious defects result in an immediate seal on the meter or appliance; secondary defects give a 15-day window before supply cutoff. Knowing how to resolve these issues and submit official proof of correction is crucial to maintaining hot water and heating without interruption.
Difference Between Main Anomalies (AP) and Secondary Anomalies (AS)
The inspection report classifies defects into two severity tiers under standard technical safety regulations:
In case of an urgent leak or pending supply cutoff, our 24/7 technical team arrives equipped with mobile workshop vans to repair pipe joints, replace degraded fittings, and resolve gas boiler breakdowns across Barcelona and surrounding regions.
- **Main Anomalies (AP Code - Imminent Hazard):** Triggers immediate protective sealing of the appliance or main meter valve. Includes measurable gas leaks, hazardous carbon monoxide buildup (ambient CO > 50 ppm), downdraft or backspill in flue ducts, cracked or disconnected flues, and room-sealed boiler breaches. Requires urgent technical intervention before supply cutoff.
- **Secondary Anomalies (AS Code - 15-Day Period):** Technical defects that do not present immediate explosive risk but must be brought up to code. Common examples: expired flexible hoses on cooktops or boilers, insufficient mandatory ventilation grilles (upper or lower), inaccessible shut-off valves, or missing combustion test points.
Step-by-Step Defect Remediation Process
Property owners have full freedom to choose any certified technical firm to perform repairs; the gas distributor cannot mandate their own internal contractors:
If the detected anomaly was accompanied by boiler pressure drops or continuous dripping, consult our guide on what to do when a boiler leaks from underneath.
- **Step 1: Contact qualified gas and heating technicians.** The technician must hold official technical accreditation and active civil liability insurance.
- **Step 2: Physical repair of defects.** Replacing corroded pipework, installing UNE-EN 14800 compliant stainless steel flexible hoses, adding exterior ventilation grilles, or adjusting condensation flue alignment.
- **Step 3: Tightness and combustion testing.** Verification with electronic differential pressure manometers at operating pressure and flue gas combustion analysis ensuring safe CO and O2 levels.
- **Step 4: Official anomaly correction documentation.** The technician completes the official proof of correction document, providing a copy to the homeowner and submitting it to the distributor portal.
How is the Gas Meter Seal Safely Removed?
Breaking an official distributor seal without authorization is strictly prohibited and carries severe fines. Once repairs are completed and the correction certificate is registered, the distributor authorizes supply re-establishment or conducts a prompt verification.
For urgent boiler breakdowns, combustion faults, or pipe repairs, our emergency technicians are dispatched immediately in mobile workshop vans: call 936 94 00 23.
FAQ
Who pays for gas inspection defect repairs in a rented apartment?
Under standard leasing law, property owners are responsible for structural gas piping, boiler replacement, and ventilation grilles. Minor wear, like flexible hose renewal on a tenant's appliance, is typically handled by the occupant.
How much time do I have before Nedgia cuts the gas supply?
For main anomalies (AP), cutoff or sealing occurs within 24 hours. For secondary anomalies (AS), you have exactly 15 business days to submit the correction report before suspension.
Can I clear the gas inspection notice myself?
No. Remediation requires an authorized technician's signature, registration number, and official combustion/pressure test documentation.
