When Should I Replace My Propane Tank?

From water heating to cooking to clothes drying, propane tanks keep many households running.

That makes it all the more important to ensure yours is in working order.

Here’s how to tell that it’s time to replace yours.

1. Look for Physical Damage

Look for signs of physical damage that compromise your propane tank’s integrity.

• Dents and dings: Tiny dents should be fine, but significant indentations can weaken the tank’s structure, making it unsafe for continued use.
• Corrosion and rust: Some surface rust is normal. However, extensive corrosion, especially in areas where the metal appears pitted or thinned, could compromise the tank’s structural integrity.
• Leaks: You might have a leak if there is a “rotten egg” odor near your tank or gas lines. Turn off the gas supply, evacuate on foot immediately and call emergency services from a safe distance.
  

2. Check Performance Issues

A well-maintained propane tank means connected appliances are working as they should. Be wary of:

• Yellow or orange flames: Propane appliances should produce a blue flame to show complete combustion. Yellow or orange flames could mean gas impurities or insufficient pressure.
• Sputtering appliances: If your appliances aren’t working consistently, that could be a sign of moisture buildup inside the tank or internal corrosion. Look out for sputtering or difficulty maintaining a steady flame.

3. Environmental Impacts

Proper tank placement can make or break a long propane life. Tanks that are regularly exposed to harsh weather conditions could face a shorter lifespan. Protect your tank by ensuring it’s situated in a shaded area, avoiding direct sunlight. For buried propane tanks, acidic or alkaline soils can corrode the tank’s exterior.

4. Proper Disposal of Old Propane Tanks

Replacing a propane tank isn’t just about removing the old one; proper disposal is crucial. Many propane suppliers offer disposal services to make sure residual gas is safely removed and the tank is recycled or disposed of according to environmental regulations.

Some areas have specialized recycling programs for propane tanks. See if your local waste management or recycling centers accept old propane tanks.

To help maintain your tank, keep up with regular inspections and pay attention to signs of damage or performance issues.
