Glass Reinforced Plastic (GRP) panel tanks are widely used for water storage across industrial, commercial, and municipal sectors due to their durability, corrosion resistance, and low maintenance requirements. To learn more about GRP panel tanks, visit our dedicated page. However, like any long-term infrastructure investment, maximizing the lifespan of your GRP panel tank requires proactive care and regular maintenance.
At Raven American Tanks, we’ve spent over two decades helping facilities across the U.S. protect their tank investments. In this guide, we’ll explore proven ways to extend GRP tank lifespan while maintaining compliance, safety, and optimal performance.
1. Schedule Regular Inspections to Extend GRP Tank Lifespan
One of the most effective ways to prolong the life of a GRP water tank is through routine inspections. These should be conducted at least annually and after any major environmental events or system changes.
Key areas to inspect include:
- Tank joints and panel connections
- Internal surfaces for signs of blistering or cracks
- Roof panels for UV degradation
- Inlet and outlet fittings for leaks
Our certified inspection team at Raven American Tanks uses advanced techniques to assess structural integrity and identify early warning signs before they become costly issues.
2. Clean the Tank Periodically to Help Extend GRP Tank Lifespan
Over time, sediment, biofilm, and contaminants can accumulate inside the tank, leading to bacterial growth and reduced water quality. Professional GRP tank cleaning should be carried out every 6 to 12 months, depending on usage and local conditions.
Raven American Tanks offers chemical-free cleaning methods and high-pressure washing systems that preserve the structural integrity of your GRP panels.
3. Monitor Water Quality and Usage to Maximize GRP Tank Lifespan
Consistently monitoring water quality can help detect issues that may affect the tank from the inside. For instance, hard water can accelerate scale buildup, while chemical imbalances can weaken internal surfaces.
Also, avoid drastic temperature or pressure fluctuations, which can cause expansion and contraction in GRP materials and weaken joints over time.
4. Protect the Tank from UV Exposure
While GRP tanks are UV-resistant, prolonged exposure to direct sunlight—especially in regions like Texas or California—can degrade the surface over years. Consider installing a protective coating, shade structure, or using UV-resistant roofing panels.
Raven American Tanks provides a range of UV protection solutions, customized for your location and tank specifications.
5. Apply Preventative Maintenance and Repairs to Prolong GRP Tank Lifespan
Don’t wait for a leak to occur. Applying preventative maintenance—such as resealing joints, reinforcing high-stress areas, or replacing worn-out gaskets—can drastically reduce repair costs and extend your tank’s usable life.
We offer ongoing maintenance contracts that include all necessary inspections, adjustments, and minor repairs to keep your tank in top condition.
6. Replace Aging Liners to Preserve Tank Performance
If your GRP tank has a liner (such as PVC or EPDM), it’s important to monitor its condition. Liners can wear down over time and require replacement to maintain tank hygiene and performance.
Our liner replacement service ensures minimal downtime and compliance with water safety standards.
