Gas Leak Repair questions, answered by experts

The best sealant for gas pipes is usually a pipe joint compound, or pipe dope. It creates a durable, leak-proof seal that is resistant to high pressure and vibrations, and it doesn’t break down like tape can. Yellow Teflon tape, or PTFE tape, can also be a good option and is a safe and reliable sealant for gas pipes when you or a pro apply it correctly.

Having gas appliances in your home can be convenient—you benefit from faster water heating, more efficient clothes drying, and more affordable home heating. However, you need to be aware of the signs of a gas leak so that you and your family can take precautions to be safe around these versatile appliances. 

Signs of a gas leak include:

  • Hissing sounds

  • Rotten egg smell

  • Higher than usual gas usage

  • Physical symptoms, such as headaches, dizziness, and nausea

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

DIY installation is not recommended due to the complexities of gas line work and venting; professional installation ensures safety and compliance.
