Propane leak detection, regulator replacement, line repair, OPD valve service, and certified leak-down testing at your driveway, storage facility, or campsite. The one RV system where a correct repair is a safety issue — handled by certified technicians across Utah and Texas.
Propane system service from Mobile RV Pro covers leak detection and certified leak-down testing, two-stage regulator replacement, propane line and fitting repair, OPD valve service, automatic changeover diagnostics, and propane detector replacement on travel trailers, fifth wheels, and motorhomes across Utah and Texas. Propane is the one RV system where a bad repair is a life-safety hazard, not just an inconvenience — every repair is pressure-tested and leak-checked before the system is returned to service. If you smell propane, leave the RV, shut off the tank if you can reach it safely, and call us — do not attempt to locate the leak yourself. Certified technicians, written estimate before any work begins.
Propane problems range from a regulator that needs replacing to an active leak that is an immediate hazard. Know the difference: a leak is an emergency, and the safe response is to leave the RV and call — not to investigate it yourself.
Leave the RV immediately, do not operate switches or flames, shut off the tank valve only if you can reach it safely, and call us from outside. Do not try to find the leak yourself.
Treat every alarm as real until proven otherwise. Ventilate, shut off the tank, and leave. A genuine alarm and a failed 7-year-old detector look identical from inside — both need professional checking.
Yellow furnace flame, fridge not cooling on propane, stove flame low across all burners — usually a failing two-stage regulator delivering incorrect pressure to the whole system.
A two-tank system that does not switch to the full tank when the first empties points to a failed regulator or changeover mechanism.
Hissing at a fitting or frost forming where there should be none can indicate a leak or regulator fault. Shut off the tank and call — do not tighten fittings on a pressurized leaking line.
A certified leak-down test verifies the whole system holds pressure. Recommended after any propane work, after winter storage, and periodically as preventive safety maintenance.
If you smell propane or your detector is alarming, this is an emergency. Get everyone out of the RV, do not flip switches or light anything, shut off the tank valve only if it is safe to reach, and call us from a safe distance. Propane is heavier than air and pools in low spots — a single spark can ignite an accumulated leak. We do not ask you to diagnose a suspected leak yourself; that is what the certified leak-down test and our equipment are for.
Mobile RV Pro services the complete low-pressure propane system from the tank to each appliance connection. Common regulators, fittings, and detectors ride on the truck so most repairs complete in a single visit — every one verified with a leak-down test before the system goes back into service.
Propane pricing is driven by the component and whether a full leak-down test is included. Most repairs — regulator, detector, fitting — are same-visit jobs. A certified leak-down test is recommended with any propane work. Ranges below are all-in: diagnostic, labor, and parts at typical cost.
| Repair Type | Typical Labor Range | Notes |
|---|---|---|
| Two-stage regulator replacement | $200 – $360 | Most common propane repair; same-visit |
| Automatic changeover regulator | $240 – $420 | Two-tank auto-switching systems |
| Certified leak-down test | $130 – $230 | Manometer test; recommended with any work |
| Propane line / fitting repair | $190 – $420 | Depends on access and line length |
| OPD valve service | $150 – $300 | DOT cylinder overfill valve |
| Pigtail / hose replacement | $120 – $240 | Tank-to-regulator connection |
| Propane detector replacement | $140 – $260 | Expires every 5–7 years |
| Leak diagnosis only (no repair) | $270 – $360 | Walk-away price if you decline repair |
Mobile RV Pro provides a written estimate before any work begins, and every propane repair includes a leak-check before the system is returned to service. We do not cut corners on propane — it is the one system where a cheap or incomplete repair is a danger to your family. If you suspect a leak, do not wait for a scheduled appointment; call and describe the situation.
Mobile RV Pro technicians are certified, background-checked, and carry full liability insurance. The company is licensed and insured to perform RV repair across Utah and Texas. If a technician damages any component while performing a hired repair, Mobile RV Pro covers the replacement 100% — both parts and labor.
Mobile RV Pro is an authorized warranty coordinator for most major extended warranty providers including Good Sam, Wholesale Warranties, Cornerstone, and National General. We coordinate repairs and payment directly with extended warranty companies on your behalf — at no extra charge.
Propane is the one RV system where "good enough" is not acceptable. Mobile RV Pro technicians are certified to work on RV LP systems, and every repair ends with a manometer leak-down test that verifies the entire system holds pressure before it goes back into service. We will not hand an RV back with a propane system we have not verified. If a suspected leak turns out to be a failed detector or a vented regulator rather than gas, you still get a straight answer and a safe system — that is the job.
Certified technicians dispatched to your location — driveway, storage facility, or campsite. No haul-in, no storage fees.
A propane fault can sideline the whole coach — no heat, no hot water, no fridge on gas, no stove. Mobile service lands in days with a leak-down test on the truck, instead of a multi-week dealership wait while your RV sits unusable.
