Septic Tanks questions, answered by experts

You can check your own septic tank, but take precautions. Locate the access lid, usually buried a few inches underground, and remove it carefully. Look for the sludge and scum levels, and if they’re high, that means pumping may be necessary. Check for odors, slow drains, or pooling water around the drain field, which could indicate issues. Never enter the tank, as toxic gases can be fatal. All of that being said, a professional inspection is safer and more thorough.

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.

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly. 

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.
