Septic Tanks questions, answered by experts

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.

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.

Choosing a reliable septic tank company starts by finding an experienced company in your area with positive customer reviews online. You can also use the following tips to help ensure you have a positive experience:

  • Choose a company that is licensed and fully insured

  • Ask the company for customer references

  • Ask if the company provides any guarantee for the repair

  • Determine the provider’s level of experience

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.

Schedule annual inspections, test water pressure, and protect the pump from freezing temperatures.
