A leaking propane hose can pose great hazards to all people living in your home. Propane gas is an important aspect of many major home appliances but it can also pose danger when its flow is not controlled or contained. Propane gas is highly flammable and dangerous to health. Any amount of gas leaking out from the tank or the hose may cause illness to people. Worse, it may cause an explosion. It is therefore paramount to immediately fix a propane hose if any sign of leaking gas is detected.

Step 1 - Turn off the Main Power System of the Propane Mechanism

Turn off the main valve or main source of the propane gas. This will cut off further leaking of gas. Turn off the main breaker to avoid the occurrence of sparks that may lead to an explosion.

Step 2 - Find the Hose that Leaks

Identify the source of the leak. Usually, a leaking hose produces a strong propane odor, indicating that gas is seeping out of it. You may also listen for a hissing sound. A hiss is usually an indication that gas is escaping out of the hose or tank.

Step 3 - Tighten the Valve of the Leaking Hose

Tighten the valve that connects the hose to the tank. Use a wrench if necessary.

Step 4 - Ensure that the Leak is Contained

See if you can still smell any leaking gas despite having tightened the valve. If the strong smell of gas persists despite the valve being tightened, it may be time to replace the hose with a new one.

Step 5 - Replace the Leaking Propane Hose

Get a replacement hose from the local hardware store and replace the old one with it. Use a thread tape to ensure that no gas will escape from it. Be aware, however, that a thread tape may not be enough to hold back the flow of escaping gas in most circumstances.

Therefore, after attaching the hose and sealing it with the tape, make sure to check again for any signs of leaking gas. Other appliances around the area may also be checked to ensure that they are not also leaking gas.

Step 6 - Have the Propane Device Checked by a Professional

Step 5 is often only a temporary fix. Other times, it may not work at all. The thread tape is not an insurance for containing propane leaks. Although it may hold the flow of escaping gas for some time, it may not last for long. Therefore, have the propane device checked by a trained professional at the soonest possible time. The professionals can provide an extensive investigation to determine the real problem behind the leak. Furthermore, they can handle all the repairs needed to make the device working safely again.

A leaking propane hose is a serious matter and should not be taken lightly. Inhalation of leaking propane gas has been reported to be the cause of death of almost 25% of people who fell victim to the dangers of carbon monoxide. It is therefore of paramount importance to get people out of the house immediately when any sign of a leak is detected. People should also stay out of their house all throughout the duration of the repair to ensure that they do not inhale any amount of gas during the repair process.
