Suburban Automatic Changeover Regulator With Shut Off Valve, 1/4" Inverted Flare x 3/8" Female NPT, 160,000 BTU

Manage two propane tanks automatically with the Suburban LP-R924 Single-Stage Automatic Changeover Propane Regulator. This 160,000 BTU/hr regulator automatically switches between two propane tanks — drawing from the primary tank until it's empty, then seamlessly switching to the reserve tank without interrupting your propane supply. The essential regulator for RVs with dual-tank setups where you don't want to be stuck without propane mid-cook or mid-night during winter heating.

What an Automatic Changeover Regulator Does

Most RVs with two propane tanks need a changeover regulator — and the automatic version is the upgrade most owners genuinely appreciate:

• Designate primary and reserve tanks using the regulator's selector
• The regulator draws propane from the primary tank as long as it has supply
• When the primary tank empties, the regulator automatically switches to the reserve tank — no interruption to propane flow, no appliances shutting off
• A visual indicator tells you when changeover has happened, so you know to refill the empty tank before the reserve runs out

That means you're never caught without propane unexpectedly — the reserve tank carries you while you arrange to refill the empty one.

160,000 BTU/hr — High-Capacity Output

The 160,000 BTU/hr capacity comfortably handles demanding RV propane loads — furnace, water heater, range, and refrigerator running simultaneously. The right capacity for most RVs, fifth wheels, and toy haulers.

Built-In Shut-Off Valve

The integrated shut-off valve lets you manually shut off propane supply at the regulator for service, transport, or storage — a meaningful safety convenience that means you don't have to close the valves at the tanks every time you need to service downstream components.

Single-Stage vs. Two-Stage Note

The LP-R924 is a single-stage regulator, while our LP-R524H and LP-R524HP are two-stage regulators. The key difference: this single-stage changeover handles the tank-switching function, while two-stage regulators provide more stable pressure delivery to appliances. In many RV installations, both are used together — the changeover regulator at the tanks, and a separate two-stage regulator downstream for appliance pressure regulation. Confirm with your installer or RV manual which configuration your system requires before ordering.
