Not all gas leaks are easy to spot. One simple method for checking exposed gas connections is the soapy water test. This inexpensive technique can help identify leaks around fittings, valves, hoses, and pipe connections.
How Does It Work?
When gas escapes through a leaking connection, it passes through the soap solution and creates bubbles. Growing or continuously forming bubbles may indicate a leak.
What You’ll Need
- Liquid dish soap
- Water
- Spray bottle or small brush
A Few Simple Steps
- Mix dish soap with water.
- Apply the solution to accessible pipe connections and fittings.
- Watch for bubbles forming around the connection.
- If bubbles continue to grow, the connection may be leaking.
Important Safety Reminder: Never use a flame to check for gas leaks. If you smell gas or suspect an active leak, leave the area immediately and contact your gas utility or emergency services from a safe location. Do not attempt to locate the leak yourself.
When Is a Gas Detector Helpful?
The soapy water test is limited to accessible connections. Portable gas detectors provide another way to identify the presence of gas in areas that may be difficult to inspect visually.
Gas-Sensing offers a variety of gas detection monitors to help professionals identify potential gas hazards.
Video Demonstration
In this video, an ozone technician, from Oxidation Technologies, reviews how to perform the soapy water test when checking for leaks in any tubing or accessories. The technician has a bottle of soapy water to spray onto the connections within this TOX oxygen concentrator to check for any suds on the connections. Suds and bubbling would indicate an air leak for this TOX unit, or a potential gas leak for other systems. It is important to check for leaks on equipment to keep people safe and equipment running properly.
