When gas is involved, Hillsboro homeowners choose MT Dunn Plumbing for installation done right, with safety as the top priority.
Every gas line installation follows a strict, methodical process built around safety and code compliance.
Technicians review what the gas line needs to power, whether it’s a range, water heater, or outdoor fixture, to determine load requirements.
Pipe diameter and run length are calculated based on total appliance BTU load and distance from the gas meter or supply source.
Necessary permits are obtained before installation begins, ensuring the work meets Hillsboro and Oregon gas code requirements.
The most direct, safe route is mapped out, minimizing bends and considering accessibility for future maintenance.
The relevant gas supply is shut off completely before any cutting, connecting, or installation work begins.
Technicians run and secure the new line using approved black steel pipe or CSST tubing, depending on the application and route.
Every joint and fitting is properly sealed and tightened to manufacturer and code specifications.
Accessible shutoff valves are installed at appropriate points, allowing gas to be isolated quickly if needed.
The completed line is pressurized and monitored over time to confirm there is no drop in pressure, which would indicate a leak.
Gas leak detection equipment is used at every joint and connection point to provide an additional layer of confirmation beyond the pressure test.
Once the line passes testing, the appliance is connected, and a final check confirms proper gas flow and appliance function.
For applicable installations, we coordinate the required inspection to finalize code compliance documentation.
Most single-appliance gas line installations are completed within two to four hours, not including inspection scheduling where required.
Gas line work comes up in a variety of situations, all of which call for professional installation. Reach out if you’re:
We install and connect gas lines for a wide range of residential applications.
From what we’ve seen, the answer depends on your home’s layout, the appliances being connected, and the route the gas line needs to follow. At MT Dunn Plumbing, we’ve installed both black steel pipe and CSST, and we’ve found that each material has advantages in the right application.
Choosing the right gas piping material is an important part of building a safe, reliable gas system. Both black steel pipe and corrugated stainless steel tubing (CSST) are approved for residential gas installations, but they aren’t designed for exactly the same situations. Selecting the most suitable material helps improve installation efficiency while meeting current plumbing and fuel gas code requirements.
We’ve installed black steel pipe in countless homes because it remains the traditional standard for strength and durability. It’s highly resistant to physical damage and is an excellent choice for exposed gas lines in basements, garages, and utility areas. The tradeoff is that it requires threaded fittings and more labor, especially on longer or more complicated installations.
CSST has become increasingly popular because its flexible design allows it to route through walls, floors, and tight spaces with fewer fittings than rigid pipe. This often speeds up installation and reduces the number of connection points along the system. Because CSST requires proper bonding and grounding for safety, our technicians complete these steps as a standard part of every installation.
In many homes, we’ve found that the best solution is a combination of both materials. Using black steel near the gas meter and main connections while running CSST through concealed or hard-to-reach spaces provides the durability of rigid pipe and the flexibility of modern tubing where each performs best.
If you’re installing a new gas line, there isn’t a one-size-fits-all answer. We’ll evaluate your home’s layout, appliance locations, and installation requirements to recommend the safest, most durable, and most practical piping solution for your specific project.
Every gas line installation we perform includes thorough safety procedures to help ensure dependable operation, code compliance, and long-term reliability. Before the system is placed into service, we verify each connection, inspect the piping, and confirm that the installation meets applicable safety standards.
