Propane is used for a variety of different purposes. Some homes use propane for water heaters, stoves and heaters. Others simply use propane for outdoor grills. Whatever the application, it can be a real problem if your propane tank runs out while you're using it. Connect multiple propane tanks to avoid that problem. Special changeover regulators make it a straightforward process. With these regulators attached, the system automatically changes from the empty tank to the second tank. The regulator even allows you to change the empty tank while the system is in use.

- 2 propane tanks
- Output hose
- Adjustable wrench (optional)
Turn the shutoff valve on each tank clockwise until the valve is completely closed. Verify that both propane tanks are fully closed.
Connect one of the pigtail hoses to the automatic changeover LPG regulator. Insert the inverted thread male end of the hose into the inverted female inlet at the top of the regulator. Tighten the fitting onto the hose by hand. Consult the manufacturer's instructions for additional tightening instructions. Some fittings require an additional quarter turn with a wrench. Repeat the process to attach the other pigtail to the other inlet.
Attach the flare fitting of one of the pigtail hoses to the nozzle on one of the propane tanks. The exact fitting may vary depending on your propane tank. Some have plastic collars that require you only to hand tighten the fitting. Metal fittings may require an additional quarter turn with an adjustable wrench. Repeat the process to attach the other pigtail hose to the other propane tank.
Insert the outlet hose into the outlet port on the bottom of the regulator and hand tighten.
Attach the outlet hose to the system. The exact instructions depend on the type of system. For example, a barbecue grill may have a different connector than a water heater. Consult the manufacturer's instructions on how to connect the outlet hose properly. In general, the hose fitting screws on to the system inlet nozzle in the same way that the regulator is attached to the propane tanks.
Open the valves on the propane tanks all the way. Turn the shutoff valves counterclockwise until they are completely open. Start the system according to the manufacturer's directions. For example, a barbecue grill normally requires you to turn a dial to open the gas valve inside the grill, and then push a button to light the grill.
Tips and warnings
- Consult the system manual for the proper hose and regulator dimensions. Different systems require different diameters to function properly.
