Before you hire a septic repair pro, make sure you get three written quotes from local companies to help you evaluate qualified candidates. Ask each company to provide proof of licensure and insurance. Finally, when you decide to hire a specific pro or company, ask for a written contract that sets out all the essential terms, including specific work expectations, a timeline, what permits are needed, who is responsible for obtaining permits, and clear payment details, including due dates.

Whether or not it’s hard to pass a perc test depends a lot on the composition of your soil. When a perc test is conducted where there’s a high concentration of sand in the soil, perc tests almost always pass. However, if your ground is dense clay or rock, it may prove difficult to pass a perc test. A low water table also helps you pass the test, as a high table means your yard isn’t draining water as efficiently.

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.

You may notice a septic smell in your yard after it rains if groundwater is entering your septic tank and causing it to overflow. If you experience septic odors after rainfall, contact a licensed plumber. They can construct a drain to redirect rainwater away from your septic tank.
