Gas Line Relocation and Rerouting in Federal Way

We carefully cap off old lines, extend new ones and perform thorough leak tests to confirm the integrity of the updated system, preventing gas leaks in your Federal Way property.

New Gas Appliance Hookups in Federal Way
Adding a new gas range, dryer or water heater needs a dedicated gas line.

We make sure of proper pipe sizing for adequate gas flow and perform all necessary connections and pressure tests for a safe, working setup in your Federal Way home.

Fire Pit and Fireplace Gas Line Installation in Federal Way, WA
Gas fire pits and fireplaces add comfort on cool evenings without the smoke and ash of wood. We run a properly sized line, install a key valve or shutoff and connect the burner assembly. Fire features need adequate clearance from structures and plants, and we confirm placement before installation. Propane systems are set up with the correct regulator and orifice.
CSST Flexible Gas Piping in Federal Way, WA
Corrugated stainless steel tubing installs faster than black iron and routes easily through attics and finished walls with fewer joints. It is a smart option for remodels and additions where opening walls is costly. River flooding and soaked ground can push water back through sewer lines, so backwater valves and sump pumps are worth considering. CSST must be bonded to the home's grounding system to reduce lightning damage risk. We use brands with fittings our plumbers are certified to install and follow the manufacturer's instructions.
Gas Line Installation for Generators in Federal Way
When installing a whole-home generator, a dedicated gas line is necessary for continuous power. We provide expert gas line installation to connect your generator to your home's gas supply. Our team ensures the line is correctly sized for the generator's BTU requirements and installed to withstand local conditions, providing reliable backup power for your Federal Way property during outages.
Pool and Spa Heater Gas Lines in Federal Way
Pool heaters are among the largest gas appliances in a home, often rated at 250,000 to 400,000 BTU. They usually sit at the equipment pad far from the meter, so line size and length are crucial. We may recommend a larger main line or a meter upgrade from your gas utility. A properly sized line lets the heater reach its rated output and heat the water efficiently.

Commercial Gas Line Installation in Federal Way
Restaurants, laundromats and light industrial spaces need gas piping sized for high-demand equipment like fryers, ovens, dryers and rooftop units. We install schedule 40 black iron or approved commercial systems, add regulators where elevated pressure is supplied and coordinate inspections.
