How to Check Your Propane Tank Level: A Step-by-Step Guide

Propane is a versatile fuel source commonly used for grilling, heating, and powering various appliances in homes and recreational vehicles. Whether you’re firing up the grill for a weekend barbecue or relying on propane to keep your home warm during the winter, it’s crucial to know how to check your propane tank’s level.

Running out of propane can be inconvenient and frustrating, but with a simple step-by-step guide, you can ensure you never get caught off guard. In this article, we will walk you through the process of checking your propane tank level by using a propane tank level gauge, so you can always stay prepared.

Why Checking Your Propane Tank Level is Important

Before we dive into the steps, let’s understand why it’s essential to check your propane tank’s level regularly. Running out of propane at the wrong time can lead to inconvenience and discomfort. For instance:

  1. Grilling: Imagine having guests over for a barbecue, and just when you’re about to start cooking, you run out of propane. This can turn a fun gathering into a frustrating experience.
  2. Heating: In colder climates, many homes rely on propane for heating. Running out of propane during a chilly night can lead to discomfort and even potential health risks.
  3. Appliances: Propane is used in various household appliances, including stoves, ovens, and water heaters. Running out of propane can disrupt your daily routines and chores.

By regularly checking your propane tank level, you can avoid these inconveniences and plan for refills or replacements in advance.

What You’ll Need

Before we get into the steps, gather the following items:

  1. Propane Tank: Ensure you have the propane tank you want to check. It’s important to perform this check with the tank in its usual operating position.
  2. Water and Dish Soap Mixture: You’ll need a solution of water and dish soap to create a soapy mixture that will help you identify propane leaks (optional but recommended for safety).
  3. Cloth or Sponge: To apply the soapy mixture to the tank’s valve and connections.
  4. Safety Gear: Always prioritize safety. Wear gloves and safety goggles when working with propane.

Now that you have everything you need, let’s go through the step-by-step process of checking your propane tank’s level.

Step 1: Ensure Safety

Safety should be your top priority when dealing with propane. Before you start, make sure you are wearing the necessary safety gear, including gloves and safety goggles. Ensure that there are no open flames or sparks in the vicinity.

Step 2: Examine the Tank

Start by visually inspecting the propane tank. Look for any signs of damage, such as dents, rust, or corrosion. If you notice any of these issues, it’s essential to address them immediately. Damaged tanks can be dangerous and may need to be replaced.

Step 3: Locate the Tank’s Gauge

Most propane tanks come equipped with a gauge that indicates the level of propane inside. The gauge is typically located near the top of the tank, close to the valve. It may be a simple analog dial or a digital display.

Step 4: Check the Gauge Reading

Read the gauge to determine the propane level in your tank. Gauges can have different designs, but they usually fall into one of the following categories:

  • Analog Dial: If your tank has an analog dial, it will display a percentage or level. A reading of 80% or above indicates a full tank, while a reading below 20% suggests it’s time for a refill.
  • Digital Display: Digital gauges often provide a more precise reading. They will display the exact amount of propane in gallons or pounds, allowing you to plan accordingly.

Step 5: Use the Water and Dish Soap Mixture (Optional)

To ensure your propane tank is not leaking, you can perform a simple leak test. Mix water and dish soap to create a soapy solution. Apply this solution to the tank’s valve and connections, including the regulator, hose, and fittings.

Caution: If you notice any bubbles forming when you apply the soapy mixture, it indicates a propane leak. In such cases, turn off the tank immediately, disconnect it from any appliances, and contact a professional for repairs.

Step 6: Record the Level

Make a note of the propane level you’ve determined from the gauge. This recorded level will help you keep track of your propane consumption over time.

Step 7: Plan for Refill or Replacement

Based on the propane level you’ve recorded, you can now plan for your next steps:

  • If the tank is above 20%: You still have a reasonable amount of propane left, but it’s a good idea to schedule a refill soon to avoid running out at an inconvenient time.
  • If the tank is below 20%: It’s time to arrange for a propane delivery or replacement. Running out of propane can be an inconvenience, so plan ahead to ensure a continuous supply.

Step 8: Secure the Tank

Once you’ve checked the propane level and planned for a refill or replacement, securely close the tank’s valve. Ensure it is tightly closed to prevent any gas leaks.

Step 9: Store the Tank Properly

If you won’t be using the propane tank for an extended period, store it in a safe and well-ventilated area. Avoid exposing it to direct sunlight, extreme temperatures, or moisture.


Regularly checking your propane tank’s level is a simple yet crucial task that ensures you never run out of propane when you need it most. By following this step-by-step guide, you can stay prepared and avoid the inconvenience of an empty tank. Remember to prioritize safety throughout the process, and if you ever suspect a propane leak, seek professional assistance immediately. With proper maintenance and monitoring, you can enjoy the benefits of propane for grilling, heating, and powering your appliances with peace of mind.
