Fiberglass storage tanks are known for strength, corrosion resistance, and long service life. However, even with these advantages, buyers sometimes overlook critical factors during the selection process. Below are the most common mistakes to avoid when choosing a fiberglass storage tank—and how to make a confident, informed decision.
1. Choosing the Wrong Tank Size
One of the most frequent mistakes is selecting a fiberglass tank that is either too small or unnecessarily large. An undersized tank may overflow, require frequent emptying, or interrupt operations. An oversized tank, on the other hand, can increase upfront costs and take up valuable space.
To avoid this issue, carefully calculate your storage volume needs. Consider peak usage, future growth, and required reserve capacity. If the tank will store wastewater or chemicals, factor in processing flow rates and holding time requirements. Fiberglass Creations offers tanks in multiple sizing options, making it easier to select the right capacity without overcomplicating the process.
2. Ignoring Chemical Compatibility
Not all stored materials behave the same way. Different chemicals react differently with materials, even corrosion-resistant ones. Assuming that all fiberglass tanks are universally compatible can lead to long-term damage.
When selecting a fiberglass storage tank, confirm compatibility with the specific liquid being stored. Consider temperature, concentration levels, and exposure duration. Fiberglass reinforced plastic (FRP) tanks are highly resistant to corrosion, but proper resin systems and construction specifications matter for optimal performance.
3. Overlooking Installation Requirements
Fiberglass tanks are lightweight compared to steel or concrete, which makes installation easier. However, this does not mean installation planning should be rushed.
Failing to consider foundation support, anchoring, wind load exposure, and site preparation can shorten the life of the tank. For above-ground fiberglass tanks, ensure the base is level and structurally sound. Proper installation prevents stress points, cracking, and shifting over time.
4. Not Planning for Future Expansion
Many businesses choose a tank based solely on current needs. While that may work today, growth can quickly make that tank inadequate.
If your operation is expanding, it may be wise to select a fiberglass tank size that accommodates moderate growth. Alternatively, ensure there is room on-site for additional tanks if capacity needs increase. Planning ahead prevents expensive upgrades later.
5. Comparing Only the Initial Purchase Price
A lower upfront price can be tempting. However, focusing only on the initial cost often leads to higher long-term expenses.
Fiberglass storage tanks are valued for their durability and low maintenance requirements. Compared to steel tanks that may rust or require coatings, fiberglass offers corrosion resistance that reduces repairs and downtime. When evaluating options, consider lifecycle cost rather than just the purchase price.
6. Ignoring Environmental Conditions
Environmental exposure plays a major role in tank performance. UV rays, temperature fluctuations, humidity, and wind all affect long-term durability.
For outdoor applications, UV protection and structural reinforcement are critical. In colder climates, consider freeze-thaw conditions. In coastal environments, salt exposure can accelerate corrosion in metal tanks—another reason fiberglass is often preferred. Selecting the correct tank design for your environment ensures maximum lifespan.
7. Failing to Verify Regulatory Compliance
Different industries have regulations governing storage tanks, especially for wastewater and chemical applications. Overlooking these requirements can lead to fines or forced replacements.
Before purchasing, verify local, state, and federal regulations that apply to your operation. Confirm the fiberglass storage tank meets relevant standards for containment, safety, and environmental protection.
8. Underestimating Maintenance Needs
Fiberglass tanks are known for low maintenance, but “low” does not mean “none.” Assuming the tank requires no inspection or care can shorten its life.
Routine inspections for fittings, seals, and structural integrity help identify small issues before they become major problems. Establishing a simple maintenance schedule ensures your fiberglass tank continues performing reliably for years.
9. Not Considering Accessory and Fitting Requirements
Inlet and outlet placement, manways, vents, and access ports are essential components of any storage system. Choosing a tank without considering these elements can create installation challenges later.
Make sure the tank configuration aligns with your system layout. Confirm fitting sizes, connection types, and accessibility for maintenance. Thinking through these details early simplifies installation and long-term use.
10. Choosing a Supplier Without Industry Experience
The quality of the fiberglass tank is only as reliable as the manufacturer behind it. Selecting a supplier without a strong understanding of industrial storage needs can result in mismatched recommendations.
Work with a company experienced in fiberglass tank manufacturing and sizing options. A knowledgeable supplier will help guide you toward the right capacity and application-specific solution rather than pushing unnecessary customization.
Final Thoughts on Selecting the Right Fiberglass Storage Tank
Choosing a fiberglass storage tank is not just about capacity—it’s about performance, safety, and long-term reliability. By avoiding these common mistakes, you can protect your investment and ensure your storage system supports your operation for years to come.
