"Very well. Clint was very professional and helpful. We originally had a different septic company out who could not locate the septic tank and still charged us. Clint came in and found the septic tan uk, checked it for us, followed up and did not charge an arm and a leg. I refer him to all of my clients now."

Septic Tanks FAQs, answered by experts

On average, septic systems last between 15 and 20 years. However, with proper care and routine septic maintenance, you may be able to extend your septic system’s life span to 30 years (or more). Some ways to keep your system in tip-top shape include scheduling a professional inspection every two to five years and reducing the flow of wastewater into your system.

Needing to pump the tank as soon as it “looks” full is a common myth about septic systems, as wastewater will eventually drain into the leach field. Instead, it’s better to determine how many solids have accumulated. A septic maintenance technician near you can test this to find out whether pumping is necessary.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

To prevent septic tank problems, save on repair costs, and keep your home running smoothly, it's essential to perform regular maintenance. Have your septic system inspected by a professional every one to three years, or annually if possible, to spot potential issues before they develop. You should also have your tank pumped every three to five years, or more frequently if recommended by a professional based on your household's usage. Additionally, be mindful of what goes into your system. Avoid flushing items like paper towels, wet wipes, and feminine hygiene products. Do not dispose of other inappropriate substances, and try to avoid excessive water usage at a single time.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables.
