"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 questions, answered by experts

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

Signs that your well is dry include a decrease in water pressure, strange odors coming from faucets, cloudy, bubbly, or discolored water, and water that’s warmer than normal. Signs that your well pump is bad are similar, but you may also notice higher-than-average electric bills, strange clicking sounds, and faucets that spit or sputter.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

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.
