Quick Answer
To inspect your water storage tank, visually check for rust, corrosion, and damage, then test the tank's structural integrity and watertightness by filling and pressurizing it.
Visual Inspection
Inspect your water storage tank for signs of rust, corrosion, and damage on the exterior and interior surfaces, particularly in areas with high humidity and exposure to water. Check for any holes, cracks, or gaps that may allow water to enter the tank. Use a flashlight and wear a pair of gloves to protect yourself from sharp edges and slippery surfaces. Remove any debris or sediment that may be obstructing your view. Take note of the tank’s age, material, and any previous repairs or maintenance.
Testing the Tank’s Structural Integrity
To test the tank’s structural integrity, fill the tank with water to the recommended capacity, then use a pressure test kit to pressurize the tank to 2-3 psi (pounds per square inch) above the maximum working pressure. Observe the tank for any signs of leaks or damage. If the tank passes the test, it indicates that it can withstand the water pressure and is safe to use. If the tank fails the test, it may be necessary to replace it or perform repairs.
Additional Inspection Techniques
Use a combination of visual inspection and testing techniques to evaluate the tank’s condition. You can also use a non-destructive testing (NDT) method, such as ultrasonic testing or radiography, to inspect the tank’s internal surfaces for any defects or damage. Consider hiring a professional to inspect the tank if you’re unsure about its condition or if you’re not familiar with the inspection process.
