Can plastic fire truck water tanks be repaired if they are damaged?

Yes, HDPE water tanks can be repaired if they are damaged. However, the repair method depends on the extent and nature of the damage. In this blog post, we will discuss in detail the methods and approaches for repairing plastic fire truck water tanks.

DIY Repairs

If plastic fire truck water tank has minor damages such as small superficial scratches, then you can probably handle the repair yourself. Using a scraper, flap disc grinder, and a small gas torch, you can clean up the tank to an almost new condition. These tools will help you to remove scratches and smooth the surface without compromising the structural integrity of the tank.

Sealing Small Cracks or Pinholes

If your fire truck water tank has small cracks or pinholes above the water level, you can use a sealant to prevent dust and small insects from getting inside. While some adhesives or caulks may adhere to polyethylene, the results can be unpredictable, especially for more serious damages.

Welding Repairs

What about more serious damage, such as cracks or larger holes? In the case of such damage, professional welding is recommended. Polyethylene welding consists of heating the plastic and fusing the contacting surfaces. For this type of repair, a welding rod is often used to connect the parts. This process requires special tools and experience, so it is best performed by a professional poly welder.

Steps for Welding Repairs:

  1. Preparation: Clean the damaged area and remove all contaminants like paint, oil, or dirt. It will help you see the damage clearly and ensures a better repair.
  2. Stress Relief: If your plastic fire truck water tank has cracks, then drill a small hole at each end to prevent further spreading.
  3. Preheating: Use a heat gun or torch to preheat the damaged area and its surroundings.
  4. Filler Application: Press the polyethylene filler material into the damaged area and use the torch to melt it smoothly. A putty knife can help achieve a neat finish.
  5. Inspection: After the repair, fill the tank with water to check for leaks and ensure the repair holds.

Consulting Professionals

If the damage is extensive or you are unsure about the repair process, contact a professional poly welder. They have the necessary skills and equipment, such as extrusion welding machines, to perform long-term and reliable repairs.

Conclusion:

Although you can handle some minor repairs on your own, more serious damage must be repaired by professionals to ensure the safety and functionality of the plastic fire truck water tanks. Regular maintenance and timely repairs are the key to extending the life of your tank.
