  • 30% You should be getting a delivery soon or be calling to schedule one.

Propane Safety: How to Read a Tank Gauge

What do I do if I smell propane?

  • When it comes to gas appliances, safety is a top priority. If you smell gas in your home, follow these steps:

  • NO FLAMES OR SPARKS. Immediately put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones. Flames or sparks from these sources can trigger an explosion or a fire.

  • LEAVE THE AREA IMMEDIATELY. Get everyone out of the building or area where you suspect gas is leaking.

  • SHUT OFF THE GAS. Turn off the main gas supply valve on your propane tank if it is safe to do so. To close the valve, turn it to the right (clockwise). See video below on how to turn off tank.

  • REPORT THE LEAK. From a neighbor's home or other nearby building away from the gas leak, call your propane retailer right away. 360-378-1025. After hours calls to Inter Island Propane will be answered by our 24 hour on call answering service.  If you can't reach your propane retailer, call 911, San Juan County Sheriffs office 360-378-4151 or the San Juan County Fire Department 360-378-FIRE (3473) .

  • DO NOT RETURN TO THE BUILDING OR AREA until your propane retailer, emergency responder, or qualified service technician determines that it is safe to do so.

  • GET YOUR SYSTEM CHECKED. Before you attempt to use any of your propane appliances, your propane retailer or a qualified service technician must check your entire system to ensure that it is leak-free.

Other Common Questions

Why isn't my tank filled to 100%

Propane is delivered and stored in liquid form. Propane liquid will expand nearly 17 times as much as water over the same temperature increase. As a result, tanks and cylinders are never completely filled with propane-gas liquid. Tanks are filled to about 80 to 85 percent of their capacity. This leaves a space above the liquid, which allows the propane liquid to expand freely due to changes in temperature.
There are several important characteristics to understand about LP gases when they are stored in containers. First, heat added to LP gases in a tank or cylinder is transferred directly from the air surrounding the container. Hot days, cool nights, rain and snow are a few of the many factors that affect the temperature of the liquid. Because of these temperature changes, you may see fluctuations in your container gauge.

What happens if my tank runs out of fuel?

Close the gas supply at the tank or cylinder. Call us before doing anything else.

How do I pay my bill?

You can pay your bill online through My Fuel Portal, by check, or give us a call.

Is the ticket my driver leaves at the door my bill?

We try to leave a ticket on every door after we deliver. You can pay it right away online or wait for your monthly statement.

Whats the difference between "will call" or "keepful/automatic"?

Will Call means you are responsible for your tank levels and calling in for a delivery. Autofill or Keepful means that we monitor your tank and make sure your house is always supplied with propane. Preferably we encourage most to be on Autofill as it allows us to create more efficient routes.

Do I have to be home when my delivery arrives?

No, if you have had a delivery from us before there is no need for you to be home when we deliver. However, if it is your first delivery it is mandatory someone is home in order for us to complete our system leak check unless we have already previously preformed the leak check.

When should I schedule my Will Call delivery?

If you are located on San Juan Island or Lopez island it is best if you call in around 25% that will give us enough time to add you to our delivery route. 
If you are on Orcas Island please call when you are close to 35%. Since we barge over every two weeks it is best that you have a least 2 weeks worth of fuel in your tank so we can get you on our next route.
