Extending the Lifespan of your Oil Storage Tank: Our Maintenance Tips and Best Practices

Oil storage tanks are an important component in the heating systems of many business premises and private properties around the UK. Whether they’re located above ground or below, and whether they’re made from steel or plastic, these tanks require regular care so that they remain safe, efficient and reliable. Neglecting routine maintenance can eventually lead to premature tank failure, repairs which prove costly and, perhaps worst of all, it can cause serious environmental issues. 

Here at Tanks R Us, we pride ourselves on providing expert guidance plus professional services to ensure every owner gets the most out of their oil tank. In this edition of our blog, we’ll offer essential tips for extending the lifespan of your oil storage tank. 

Inspections 

This is you first line of defence against problems. Routine inspections are critical in identifying early signs of wear, corrosion or damage that could compromise your tank. Businesses (and homeowners) should carry out visual checks on their tank (or tanks) at least once a month and arrange for an annual professional inspection. There are various visible signs of problems. 

• Rust or discolouration on metal tanks 
• Cracks or bulges on plastic tanks 
• Signs of oil leaks or wet spots around the base 
• Unusual smells or changes in fuel usage 
• Deterioration of tank supports pipework or fittings 

The team at Tanks R Us is trained to conduct thorough inspections and provide detailed reports, ensuring any issues your tank may encounter are addressed promptly. 

Cleaning 

Over time, sludge and water can gather at the bottom of oil tanks. This build-up of sludge can lead to blocked pipes, inefficient fuel burning and, ultimately, damage to the tank itself. Cleaning regularly is an essential part of maintaining fuel quality and extending tank life. Typically, a thorough clean should be done every 3 to 5 years, but this can vary depending on tank age, usage and environmental conditions. There are certain signs that your tank needs cleaning. 

• Reduced heating efficiency 
• Filter blockages 
• Noisy boiler operation 
• Evidence of sludge in drained samples 

At Tanks R Us we can provide a full tank cleaning service using specialised equipment, which will remove contaminants without harming the tank itself. Our technicians will also dispose safely of waste materials (in compliance with environmental regulations). 

Maintenance 

Preventive maintenance can drastically reduce the risk of sudden tank failure. Putting together a maintenance schedule with simple monthly checks and annual professional servicing can save you time, money and stress in the long run. There are certain maintenance measures you should take. 

• Keep the area around the tank clear of vegetation and debris 
• Ensure the tank is installed on a stable, level base 
• Protect the tank from weather extremes with appropriate covers or shelters 
• Regularly test for water contamination in the fuel 
• Replace worn parts like filters and seals promptly 

Tanks R Us provides tailor-made maintenance packages to suit every tank type and usage level, so you can enjoy proper peace of mind all year round. 

Problems and Solutions 

Even with regular care, tanks can develop issues due to age, poor installation or external factors. Understanding the most common problems can help you act quickly and minimise damage. 

Corrosion: Metal tanks are especially susceptible to rust, which can weaken the structure and cause leaks. Applying protective coatings and installing water filters can mitigate against this risk. 

Cracking and warping: Plastic tanks may crack due to UV exposure or freezing temperatures. Installing a UV-resistant cover and insulating the tank can help. 

Contamination: Rainwater or condensation can enter the tank, which contributes to the growth of sludge. Installing a water trap and regularly testing the fuel can prevent contamination. 

Theft or vandalism: Oil is a valuable resource and can attract thieves. You should make sure you the tank with locking caps. It’s also worth installing motion sensor lights or investing in a monitoring system. 

Tanks R Us offers diagnostic services to identify tank issues early, and we can also recommend cost-effective solutions to extend your tank’s service life.

Replacement 

Even the best-maintained tanks have a finite lifespan. Most plastic tanks last between 15 and 20 years, while steel oil tanks may last up to 25 years if they are cared for properly. If your tank shows repeated signs of wear or frequent leaks, or no longer meets current regulations, it may be time to consider an upgrade. Tanks R Us offers full tank replacement services, including site assessment, removal of the old unit, installation of a new tank and proper disposal of any waste.

Proper maintenance isn’t just about saving money—it also helps protect the environment. Leaking tanks can contaminate soil and water sources, leading to hefty clean-up costs and legal liabilities. There are several eco-friendly things you can do. 

• Install secondary containment systems (bunded tanks) 
• Use environmentally approved fuel additives 
• Regularly check for leaks and addressing them immediately 

By following best practices and scheduling regular servicing, tank owners can do their part in supporting environmental protection.
