Q: Are septic tanks bad for the environment?

• <div><p>Septic tanks aren&rsquo;t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.</p></div>

Q: How do you add or replenish good bacteria in a septic tank?

• <div><p>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.</p></div>

Q: How do I know which size well pressure tank I need?

• <div><p><a href="https://www.angi.com/articles/how-to-size-a-well-pressure-tank.htm">How to size a well pressure tank</a> is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60&mdash;the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. </p></div>

Q: Is septic smell harmful?

• <div><p>A septic smell may be harmful because <a href="https://www.angi.com/articles/is-sewer-gas-dangerous.htm">sewer gas is dangerous</a> depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.</p></div>

Q: What can I add to my septic tank to speed up decomposition?

• <div><p>You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.</p></div>
