煤氣已經關閉, 但還是有一股氣味

如果燃氣關閉後仍有異味, 可能表明存在洩漏.

燃氣掣附近可檢測到的氣味通常表明閥門或燃氣管嘅膠接頭处洩漏. It is recommended to replace the gas valve in such instances.

也, if the rubber appears aged, replacing it timely is essential. Under these circumstances, the gas cylinder itself is usually not the issue and can generally be discounted.
