Septic Tanks questions, answered by experts

A well pressure tank can last up to 15 years. However, how long your well pressure tank lasts depends on a few factors. If you have an appropriately sized tank from a high-quality brand, it’s more likely to last longer. Maintaining clean well water also helps since there won’t be sediment mucking up the works. Keeping to a maintenance schedule ensures that you catch minor repairs before they turn into big problems that require a complete tank replacement.

Preventing septic tank problems can help save on overall septic tank repair costs and keep your home running smoothly. To ensure that your tank continues to function correctly, you should:

  • Have your septic tank system inspected every one to three years.

  • Have your septic tank pumped every three to five years or as needed based on your usage.

  • Avoid flushing paper towels, wet wipes, and feminine hygiene products.

  • Avoid excess water usage at one single time.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system. 

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.
