Getting the grade right for tank installations can be a real challenge, especially when it comes to plastic tanks. As @loganallen90 points out in his video, the hardest part isn’t just digging the hole—it’s making sure that the tank sits perfectly level. If the grade is off even a little, the tank can shift, causing long-term problems like leaks or drainage issues. Plastic tanks are typically more prone to movement, making grading even more critical.
