"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks FAQs, answered by experts

Most home wells start at 100 feet, and many go as deep as 200 or 300 feet. 

It takes quite a lot of water to meet the demands of showers, toilets, faucets, and appliances like dishwashers and laundry machines, and shallow wells struggle to provide this amount quickly. If you anticipate having high water usage in the future, it’s often better to drill slightly deeper and give yourself a bit more water storage than you need.

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

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.

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.
