Septic Tanks questions, answered by experts

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

There are several signs that your well pump’s pressure switch isn’t working as it should. For instance, if your pump runs continuously, produces weak water pressure, or doesn’t turn on at all, you may have a bad switch. Also, if your water flow is erratic or unpredictable, it could indicate an issue with your pressure switch.

Saving money on property taxes and having direct control over your waste system are both pros when buying a house with a septic tank. However, it’s easier on the house and the yard if a home can be hooked up to a municipal system, which is why septic tanks are best for homes where that isn’t an option. Expensive repairs, potential odor issues, and regular maintenance are all cons of septic systems. 

Most cesspools are buried about 1 to 3 feet below ground. The cesspool itself can be between 8 to 10 feet deep, with an average capacity of 750 to 1,250 gallons. If you’re planning to fill in a cesspool, be prepared by knowing the size of your original tank so you can buy the appropriate amount of soil.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.
