Adding a new gas range, dryer or water heater requires a dedicated gas line.

Gas Water Heater and Tankless Line Upgrades in Spokane Valley, WA
Tankless water heaters often need up to 199,000 BTU, far more than the 40,000 BTU a typical tank heater uses. Many existing 1/2 inch lines cannot supply that demand, which causes error codes and lukewarm water. We calculate the full house load and upsize the line to 3/4 inch or larger as needed. This upgrade is one of the most critical steps in a successful tankless conversion.

Frequently Asked Questions About Gas Line Installation in Spokane Valley
The cost of gas line installation in Spokane Valley, WA varies a lot depending on the length of the line, the piping material, routing complexity and the number of appliances. A simple appliance hookup might range from $400 to $800, while a whole-home installation could be several thousand dollars. We provide a clear estimate after an on-site assessment.
Materials like CSST and fittings carry manufacturer warranties, and we warranty our installation labor. We will go over the specific terms with you before work starts.
FHN Plumbing stands behind our work with a full warranty on our gas line installations. This usually covers workmanship for a set period and may include manufacturer warranties on materials. Specific warranty details will be provided with your project estimate.
Gas lines usually do not need frequent inspections once installed correctly, but it is good practice to have them checked during routine plumbing inspections or if you notice unusual smells or sounds. Mid-century homes often have galvanized supply lines and cast iron drains, while some 1980s and 1990s homes were plumbed with gray polybutylene. For older homes in Spokane Valley, an inspection every 5 to 10 years can help identify potential issues.
We use trusted brands for gas line components, including Gastite and TracPipe for CSST, and high-quality black iron pipe from reputable manufacturers. We also install dependable shutoff valves and fittings from brands like Mueller and Nibco for durability and safety.
We mainly install black iron pipe and corrugated stainless steel tubing, or CSST. Black iron is a traditional, rigid option, while CSST offers flexibility and faster installation. Both are safe and code-compliant when installed by licensed professionals, and the choice often depends on the application and property layout.
We use schedule 40 black iron, CSST flexible tubing and yellow polyethylene for underground runs. The choice is based on location, code requirements and the appliance.
Most residential gas line installations for a single appliance can be completed in a few hours to one day. More complex projects, such as extending lines for outdoor kitchens or multiple appliances, might take one to two days. This timeline does not include permitting and inspections, which can add several days to the schedule.
