"Excellent value. Superior work. We had multiple stumps removed, an old 16â x32â raised bed garden removed. One of the stumps was right next to our septic tank. JReid was able to remove this stump without harming our tank at all. This stump was within 1ft of the tank, and it was carefully removed with expertise. I would definitely recommend them!"

"This company called me as I clicked yes to help. Very knowledgeable, he asked me questions, figured out my problem and told me where to get part and pretty much how to install it and test it! He had prices, options and I will call him anytime I have water issues! The rest of the day I answered calls and was told I needed them to come and charge me tons of money.. I am up and running with a phone call! Almost nobody does that anymore. Satisfaction went through the roof with Drain Cleaners Sewer and Septic Professionals, they knew all about wells, pumps, tanks and control boxes! Love these guys! thank you again, Dean R. Hubbel"

Septic Tanks FAQs, answered by experts

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

Common problems include low water pressure, no water, and strange noises. Regular maintenance prevents many issues.
