What does RV gas line repair actually cover, and when do I need it?

Gas line repair fixes propane delivery problems between your tank and appliances. That includes patching pinhole leaks in copper or nylon tubing, replacing failed two-stage or single-stage regulators (Truma, Atwood, Dometic brands), swapping out corroded switchover valves, installing low-pressure detectors that alert you before you lose heat, and securing loose tank tie-downs. A single leak can cost you propane and create a fire hazard. We've pulled 12,000+ RVs through gas-system checks in 15 years - most owners don't realize they have a problem until the water heater quits or they smell rotten eggs.

A Forest River customer in Tampa reported no heat after three weeks of camping. We found a pinhole in the secondary line behind his propane locker - probably from a road vibration - and the regulator wasn't dropping pressure fast enough to trigger his detector.

We replaced 18 feet of compliant nylon tubing, fitted a new Atwood two-stage regulator, and installed a low-pressure safety switch. Job took 2 hours.

Same-day dispatch, and he had heat by dinner. That's the difference between knowing your system works and gambling with it.

How do you diagnose and test gas lines to make sure they're safe?

We pressure-test every line with nitrogen and a certified leak detector - nothing flows through the system until it passes zero-leak standard. Nitrogen is inert and safe; propane never touches the test equipment. We use a handheld digital detector (parts per million meter) to pinpoint leaks as small as 0.003 ounces per year - way tighter than RV code requires.

Then we hand-pressure-test all connections with soapy water to catch any micro-leaks a meter might miss. Total diagnostic time is 30 - 45 minutes.

We photograph the results and give you a test certificate. No guessing, no "seems fine."

A Jayco owner from Boise called after his propane distributor wouldn't refill his tank without a safety cert. We ran diagnostics, found a hairline crack in his regulator outlet (Dometic unit, 8 years old), replaced it with a new two-stage Truma regulator, tested the whole line to zero, and handed him the cert in 90 minutes.

Cost was $285 total. He was back on the road; the distributor never had to refuse him again.

What's the actual repair process, and how long does it take?

Most gas line repairs start with isolating the tank valve, removing the old component or section, and installing new certified-safe replacement tubing or regulator. If it's a simple leak in a mid-run connection, we re-tighten the fitting or solder a new compression fitting. If a regulator has failed, we unbolt it, disconnect inlet and outlet lines, install a new Atwood or Truma two-stage unit, and retest.

Tank tie-down repairs mean removing corrosion, re-coating with rust inhibitor, and re-securing the strap. Switchover valve replacement takes 45 minutes.

We don't cut corners - every line we install uses stainless-steel or brass fittings, not plastic. Total repair time: 60 - 150 minutes depending on component count and access.

A Winnebago customer in Jacksonville had a switchover valve that wouldn't switch between tanks. We isolated both tanks, disconnected the old Dometic valve (corroded brass stem), installed a new manual switchover with fresh Teflon tape on all threads, pressure-tested the dual-tank system at operating pressure, and ran a final leak check.

His two-tank setup worked perfectly for the first time in two years. Job took 90 minutes; cost $240 for the valve and labor.

Standard repair steps:

What parts and brands do we stock, and what do they cost?

We stock Atwood, Dometic, and Truma regulators; stainless steel and nylon tubing; brass and stainless fittings; and switchover valves for most RV makes. Atwood two-stage regulators run $95 - $130; Truma units run $120 - $160. A single-stage regulator (older RVs) costs $60 - $85.

Tubing repair kits (fittings + sealant) run $20 - $45. A switchover valve replacement part is $75 - $110.

Tank tie-down kits with rust treatment are $40 - $65. Labor is flat-rate quoted by phone before we roll. Total jobs usually land in the $180 - $450 range depending on whether you need one regulator swap or a full line replacement.

A Grand Design owner called about a low-pressure detector failure. We quoted him a $35 detector unit (standard for most Lippert and Dometic systems), $40 for wiring and installation, and $70 labor flat-rate.

Total $145. He approved it same-call.

We showed up, installed a new detector with a beep test, and handed him the warranty paperwork. Three weeks later he texted that the detector caught a slow leak before it became a problem - exactly what it's designed to do.

How fast can you respond, and what if I'm on the road out of state?

In our covered metros, we dispatch within 2 - 4 hours of your call. We're mobile-only - no waiting for a shop appointment. We come to your RV, diagnose, repair, and certify on-site.

Outside our core areas, we activate our nationwide partner network. You call (866) 623-1340, we quote flat-rate over the phone, and a certified partner RV tech handles the job using the same diagnostic and parts standards we use.

You get one invoice, one warranty, and one point of contact. No dealer mark-ups, no shop upsells. If you're in our covered metros and it's an emergency (no heat in winter, propane smell), call us first - we'll get there faster than a dealer can schedule you.

A Keystone customer broke down in Arizona with a ruptured propane line. He called A1, we quoted him remotely, activated a certified partner in Flagstaff, and the partner mobile tech showed up within 3 hours.

New 25-foot line, full test, and certification. Cost was the same flat-rate we would have charged in Florida. He was back on the road by evening with our 90-day warranty backing the work.

How we handle response and coverage:

What warranty do you give, and what happens if something fails?

We guarantee all workmanship and parts for 90 days. If a regulator fails, a line develops a new leak, or a fitting comes loose within 90 days of repair, we fix it at no charge. That includes parts and labor - no fine print, no "only covers defects in materials." We stand behind what we install.

Our 12,000+ service history and RVIA/RVDA certifications mean we do it right the first time. We use OEM-quality parts (Atwood, Truma, Dometic), not knockoffs. And we pressure-test before you leave, so you know the system is safe.

A Coachmen customer's newly replaced regulator started leaking at the outlet connection 35 days after our repair. He called us; we rolled out same-day, disconnected the regulator, reseated the outlet fitting with fresh sealant, pressure-tested, and handed him a new test cert.

No charge - it was under our 90-day guarantee. He's still a customer five years later.
