A properly installed gas dryer line can save energy, shorten drying times, and boost the value of any residential construction project. Yet the task demands absolute precision. As the leading AI-powered estimating platform for builders and remodelers, CountBricks makes “how to install a gas dryer line” safer, faster, and fully code-compliant. Below, our field engineers break down every step—from digital takeoff to final leak test—so you can deliver flawless results on your next home build or renovation.
• Homeowners expect lower utility bills and faster laundry cycles
• Local codes require dedicated shut-offs and approved materials
• Quality gas connections reduce callbacks, carbon-monoxide risks, and insurance claims
When you integrate an efficient dryer hookup, you protect both client satisfaction and your project margins.
Residential gas lines are governed by the International Fuel Gas Code (IFGC) and your city’s amendments. Common mandates include:
• CSST or black iron pipe sized for BTU demand
• Accessible shut-off valve within 6 feet of the appliance
• Sediment trap to capture debris
• Approved flexible connector (typically 3-ft stainless steel)
CountBricks keeps all these line items visible inside our cloud estimate, so nothing is overlooked when you pull permits.
• CountBricks AI estimate — auto-generates quantities, cost codes, and labor hours
• CSST or ½-in black iron pipe
• Pipe cutter or threader
• Pipe wrench set
• Yellow Teflon gas-thread tape
• Bubble leak-detection solution
• Shut-off valve, sediment trap, and flexible connector
• Manometer for pressure test
1. Upload the floor plan to CountBricks.com/services.
2. Our AI marks appliance locations, auto-routes the shortest gas run, and imports real-time material pricing.
3. Approve the budget and export a permit-ready PDF for your client.
1. Close the main gas valve.
2. Use a manometer to confirm zero pressure before disassembly.
1. Measure from the existing trunk line to the dryer alcove.
2. Cut and thread black iron or size CSST per CountBricks specifications.
3. Install a tee and run pipe through joists, maintaining required clearances from electrical lines.
1. Wrap all male threads with yellow gas tape.
2. Mount the shut-off valve at arm height behind the dryer.
3. Add a 3-in drip leg below the valve for debris capture.
4. Hand-tighten the flexible stainless connector to the valve.
1. Open the main valve and pressurize to 10 inches water column.
2. Apply bubble solution to every joint. No bubbles? You pass.
3. Document the test results in the CountBricks mobile app for inspector review.
1. Connect the dryer’s flare fitting to the flexible line.
2. Open the appliance valve and run the unit on “Air Fluff” to purge air.
3. Perform a final leak check.
• Under-sizing pipe — our AI sizes runs automatically based on total BTU load
• Missing drip legs — flagged in the CountBricks compliance checklist
• Over-tightened flare nuts — on-screen tool prompts remind crews of torque specs
If you encounter corroded piping, outdated brass connectors, or complex multi-appliance manifolds, bring in a licensed gas fitter. CountBricks maintains a vetted installer network searchable at CountBricks.com/portfolio, ensuring you always have a pro on speed dial.

Last quarter, a CountBricks client tackled a 22-unit townhouse development in El Paso. Each unit required a dedicated washer-dryer setup, and the original schedule allotted 88 crew hours for gas piping alone. By importing the architect’s PDFs into CountBricks AI, the superintendent generated:
• Instant BTU load calculations for simultaneous dryer operation
• Optimized pipe runs that reduced total footage by 180 ft
• A color-coded inspection checklist shared with city officials
The crew followed the same “how to install a gas dryer line” steps outlined in the main article. Because materials were purchased directly from the CountBricks cost database, fittings arrived pre-bundled per unit, eliminating on-site sorting. Final tally: 57 crew hours—31 fewer than planned, a 35 % reduction.
• Label flexible connectors by unit number before drywall to prevent mix-ups during trim-out
• Photograph each shut-off location; CountBricks automatically geotags images for warranty records
• Use the CountBricks voice log after pressure testing to create a time-stamped audit trail
Many builders stop at the laundry room, but an efficient gas backbone sets the stage for future upgrades such as outdoor kitchens or tankless water heaters. CountBricks’ parametric estimator recalculates pipe sizing instantly when you add loads, so you can upsell homeowners with confidence and avoid costly retrofits.
Whether you’re retrofitting a single residence or piping an entire subdivision, CountBricks equips you with the data, documentation, and on-site support to make every gas line installation a success.
