You need to install the gas piping carefully to avoid leaks and keep your standby generator running safely. Here is how you do it:
Measure and cut the gas pipes to fit your setup. Use a pipe cutter for clean edges.
Choose the right pipe material. Steel works for high-pressure systems. Copper fits most homes. Polyethylene is best for underground lines.
Make sure the pipe size matches your generator’s needs. If the pipe is too small, your generator will not get enough fuel.
Install a shutoff valve close to the generator. This lets you stop the gas quickly in an emergency.
Use connectors made for gas lines. These keep the connections tight and safe.
Apply thread sealant tape or pipe joint compound to all threaded ends before you connect them.
Tighten all joints with the right tools. Do not over-tighten or leave them loose.
Double-check every connection for tightness.
️ Note: Many people make mistakes here. They use the wrong pipe size or material, skip the shutoff valve, or do not seal the joints well. These mistakes can cause leaks, noise, or even damage your generator.
Now you connect the gas line to your standby generator. Follow these steps:
Find the gas inlet on your generator. It is usually marked on the unit.
