Overview

Gas work is not DIY — here's what proper repair looks like

Gas plumbing isn't a place to shortcut. A loose fitting, a bad flare joint, a nicked line behind drywall — any one of those is a slow leak that can go undetected for weeks, then ignite. Every gas job we do is done by a licensed gas-certified plumber, with a city permit pulled, pressure-tested to code, and signed off by a city inspector. If a contractor tells you gas work doesn't need a permit, find a different contractor.

When to call us for gas work

  1. You smell gas — anywhere near a stove, water heater, furnace, dryer, or outside near the meter. Leave the house, shut the gas meter off if safe, call us and the utility
  2. Pilot light won't stay lit — sometimes a faulty thermocouple, sometimes a gas supply issue. We diagnose both sides
  3. Flex connector looks corroded or brittle — required replacement every 10-15 years
  4. New appliance install — gas range, dryer, furnace, water heater, tankless, fireplace insert, outdoor grill, patio heater, fire pit, pool heater
  5. Line extension — running gas to the garage, backyard, detached shop, addition, or new appliance location
  6. Gas line upgrade for tankless — existing 1/2" line won't supply a tankless water heater, needs upsize to 3/4" or 1"
  7. Remodel or addition — capping off existing gas, relocating lines, adding new drops
  8. Gas meter capacity issue — when you add appliances and the meter is undersized, we coordinate the utility upgrade

How gas leak detection works

Multiple tools depending on the situation. Electronic gas sniffers that detect methane concentrations as low as 50 ppm — useful for pinpointing a general leak area. Bubble testing on visible fittings — soapy solution on every joint, bubbles mean leak. Pressure testing — we isolate a section of line, pressurize it to 10-15 PSI with air, and watch a gauge for pressure drop over 15 minutes. A drop means a leak somewhere in that section, and we isolate further until we've found it.

For a leak behind a wall, we combine electronic detection with line tracing and sometimes thermal imaging. Once located, we cut the smallest possible access, repair with proper black iron pipe (standard interior gas), CSST (flexible corrugated stainless), or tracer-wire PE (exterior underground). All joints threaded and pipe-doped properly, re-tested to code, inspected by the city.

What we install

New appliance drops — stove, dryer, furnace, water heater, tankless, fireplace. $225-$585 depending on distance from main. Outdoor gas lines — grill, fire pit, patio heater, pool heater. $485-$1,850 depending on trench length and obstacles. Gas line upsizing — from 1/2" to 3/4" or 1" for tankless or new appliance demand. $485-$1,450. Full house re-gas — rare but occasionally needed when older CSST or black iron is failing or not up to code. $3,500-$12,500 depending on size.

Utah-specific gas considerations

Salt Lake Valley has good natural gas service through Dominion Energy, which means most residential work is pretty standard. Older homes built 1920-1960 sometimes have remnant lead-jointed cast iron gas lines that need full replacement when any major work is done. CSST flexible gas lines installed between 1990-2010 are under scrutiny for lightning-arc failures; current code requires bonding. Park City, Alpine, and some unincorporated areas use propane instead of natural gas, which changes regulator and pressure requirements.

What Valley does differently

Every gas tech on our fleet is licensed for gas work through Utah DOPL. Every job gets a city permit — Salt Lake City, Sandy, Murray, West Valley, West Jordan, Provo, Orem, Ogden — all require it, we handle it. Every line we install gets pressure-tested to code (15 PSI for 15 minutes minimum, longer on larger systems) before drywall closes up. Every permit gets inspected by the city. 1-year workmanship warranty on all gas plumbing work.

Emergency leak calls get 60-90 minute dispatch. If you smell gas right now, don't wait — leave the house and call.

The Process

How a Gas Line Repair or Install Runs

Valley Plumbing gas technician pressure-testing a gas line with a pressure gauge

On the truck

Cable machine, jetter, and pipe camera — every call.

  1. Triage and safety first

    If it's an active gas leak, leave the house, shut off the meter if safe, and call. We dispatch in 60-90 minutes and stop the leak before anything else. For non-emergency work — new appliance, line extension — we schedule an in-home assessment.

  2. Assess and quote

    Tech confirms pipe path, existing line sizing, meter capacity, and code requirements for the work. You get a flat-rate quote that includes the permit, inspection, and workmanship warranty.

  3. Permit and install

    We pull the city permit before work starts. Install is typically a half-day for a new appliance drop, 1-2 days for a longer line extension or upgrade. Black iron, CSST, or PE pipe depending on code and location.

  4. Pressure test to code

    Every new line is pressure-tested to 15 PSI minimum for a minimum of 15 minutes. Bigger systems get longer test times. Failure to hold pressure means a leak, which we find and fix before proceeding.

  5. City inspection and warranty

    City inspector verifies the work to code. Once passed, we connect the appliance, leak-test at the fittings, turn the gas on, and commission the appliance. 1-year workmanship warranty and permit sign-off on the paperwork.
