"They put in new drains and a dry well for our driveway, carport, and front yard. When the first dry well wasn't large enough to hold all the runoff from a heavy storm, they came back and added a second for free. Excellent customer service, very responsive, good work."

Septic Tanks FAQs, answered by experts

Septic tanks appear full after pumping because the liquid levels have returned to normal. If you can see the pipe, the tank is empty. However, heavy rain can cause septic tanks to fill faster than normal. You might also have leaky pipes or faucets, causing extra water to drip down the drains and into the septic tank.

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.
