"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Very positive experience. Clint is very easy to speak with and made a point of keeping us informed during the project. We had to replace our septic tank and they also built a new leach line. All the men who worked on the project were very respectful. Our original quote was honored and the work well done. We feel great about our choice. I would recommend Clint Pridmore Construction with full confidence that everyone would be as happy as we were with our project."

Septic Tanks questions, answered by experts

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe 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 experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.
