My American Standard Boiler Leaks in the Center

Identification

• American Standard boilers contain cast iron heat exchangers, which maximizes fuel efficiency. These boilers also have insulation that traps heat inside the boiler and keeps sound to a minimum while the boiler is running. Any leaks in an American Standard boiler should be repaired promptly to avoid carbon monoxide poisoning and combustion spillage.

Causes

• Cast iron boilers may develop leaks as they age. The primary cause of leaks in the center of the boiler is a crack that has developed in a section of the boiler. Another cause of leaks in American Standard boilers is rotted out return lines, which occur with frequent use and are more common in older boilers.

Solution

• If your American Standard boiler is leaking from a crack in a section of the boiler, it will be necessary to replace the appliance as it is not possible to repair it. Leaks in rotted out return lines can be repaired by replacing the return pipe in the boiler. Homeowners who are not familiar with repairing heating appliances may wish to hire a repair professional for best results.

Considerations

• After replacing a rotted out return line with a new return pipe, you must test the boiler to be sure it is working efficiently and carbon monoxide is not seeping into your home. A combustion analysis test can determine if there are any issues with your boiler after repair. Combustion analysis tests are performed with a digital analyzer that can be purchased at a home repair store.
