Hooking up a propane tank to an RV

Yes, you can hook up a 20 lb propane tank to an RV, but it’s essential to do it safely and ensure compatibility with your RV’s propane system. Many RVs are designed to use larger propane tanks (like 30 lb or 40 lb tanks), but a 20 lb tank can work as long as you use the appropriate connections and regulators.


Steps to Connect a 20 lb Propane Tank to an RV

  1. Verify Compatibility:
    • Check your RV’s propane system requirements and ensure a 20 lb tank will provide sufficient fuel for your needs.
    • Ensure your RV’s propane system uses the same type of connector (usually an ACME or POL fitting).
  2. Get the Right Adapter or Hose:
    • Most 20 lb propane tanks use an ACME fitting or a QCC1 valve.
    • Purchase a propane adapter hose specifically designed to connect a 20 lb propane tank to an RV’s propane system.
      • Example: A high-pressure propane hose with an ACME nut on one end and the appropriate connection for your RV on the other.
  3. Turn Off Propane Appliances:
    • Before connecting the tank, turn off all propane-powered appliances in your RV to ensure safety.
  4. Connect the 20 lb Tank:
    • Attach the hose’s ACME fitting to the 20 lb propane tank. Ensure it’s snug but avoid overtightening.
    • Connect the other end of the hose to your RV’s propane system, which might involve attaching it to an existing regulator or directly to the propane inlet.
  5. Check for Leaks:
    • Open the valve on the propane tank slowly.
    • Use soapy water to check for leaks at all connections. If bubbles form, tighten the connections or replace faulty components.
  6. Use the Propane Tank:
    • Once you’ve verified there are no leaks, you can use the propane tank to fuel your RV appliances.

Additional Considerations

  • Regulator:
    • Most RVs have a built-in regulator to control propane pressure. If you’re bypassing the RV’s onboard tanks, ensure the regulator is functioning correctly.
    • If your RV doesn’t have a regulator, you’ll need an inline regulator compatible with the 20 lb tank.
  • Tank Positioning:
    • Always place the 20 lb tank upright and secure it to prevent tipping or movement while in use or transit.
  • Usage Duration:
    • A 20 lb propane tank contains approximately 4.7 gallons of propane. Its duration depends on your propane usage:
      • A furnace uses about 1 gallon per hour.
      • A stove or refrigerator uses less.
  • Portable Tanks for Extended Stays:
    • If you’re staying in one location for an extended period, a 20 lb tank can be a convenient backup or supplemental propane source.

When to Use a 20 lb Tank

  • As a backup when the RV’s main tanks are empty.
  • For short trips or temporary use.
  • When connecting to external propane appliances (e.g., grills or portable heaters).

By using the proper connections and taking safety precautions, a 20 lb propane tank can be a practical option for powering your RV’s propane appliances.
