"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."

"Charles is perhaps the most friendly and professional contractor I have ever hired. He removed an old septic tank and replaced it with a new one along with a better leaching field. He then repaired and seeded the lawn where the work was done. I also had him remove a shrub and deliver stones for some landscape improvement. A genuinely nice person as well. I cannot recommend him enough."

Septic Tanks questions, answered by experts

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

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.

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.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.
