"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.
