Field notes
LP gas problems are safety-sensitive by nature. Here’s how to tell a routine fix from something that needs a professional immediately — plus the regulator, tank, and detector reference every owner should know.

LP Detector Alarming with No Obvious Cause
— Detectors have a service life of roughly 5 years from date of manufacture — check the manufacture date before assuming a leak; the internal sensor degrades with age regardless of use — Cleaning products, aerosols, a...
Regulators & Auto-Changeover Valves
Most RVs use a two-stage regulator: a first stage that drops tank pressure to roughly 10 PSI, then a second stage that drops it to the appliance-ready 11″ W.C. (about 0.5 PSI). Dual-cylinder trailers add an auto-chang...
Cylinders vs. ASME Tanks
— DOT cylinders (portable, vertical, removable — typical on trailers) require recertification every 12 years from manufacture, stamped on the collar — ASME tanks (permanently mounted, horizontal — typical on motorhome...
