Septic Tanks FAQs, answered by experts

The size of your water well pressure tank is limited only by your budget and the amount of space you have to use. Larger tanks can hold more water, meaning your well pump will need to cycle less often. This can extend the life of both the pressure tank and your well pump. Larger tanks cost more and take up more room, though.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

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.
