Cathodic Protection Testing

Protect your underground tank

cathodic protectionUnderground propane tanks offer several advantages.

In very hot weather, the tanks are shielded from heat that may cause the propane in an aboveground tank to expand to dangerous levels.

Some people find propane tanks unattractive, or the tanks are placed somewhere that doesn’t work for them, like close to their patio. The tanks stand out and can distract from nice landscaping. Many businesses and multifamily buildings have underground propane tanks as well.

If you have an underground propane tank, you likely have a “sacrificial” cathodic protection system, which prevents corrosion by applying a direct current from an external source. This makes the tank itself a cathode, preventing the electrochemical reaction between the tank and the soil around it. That reaction is what creates corrosion.

A corroded underground propane tank can leak, creating the risk of injury or property damage. If your propane tank was installed after January 1, 2011, a cathodic protection testing system was installed with it. Bedford Valley Petroleum provides the professional testing of that system, which is required by law in many areas.

Do I need cathodic protection testing?

An underground propane tank is a major investment for your home or business. Cathodic protection testing helps you protect that investment.

Here are some questions to ask yourself:

You should be testing for cathodic protection within 3 months of initial install, 6 months after that, than it’s a year, and then 3 years.
