Septic Tanks FAQs, answered by experts

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

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.

Many variables, such as home size, type of engineered system, the material used, soil conditions, and water usage, dictate how long your system will last. On average, most homeowners find that their system lasts 15 to 20 years, though it’s not unheard of for them to last up to 40 years with annual and preventative septic maintenance.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

The lifespan of your well casing depends mainly on the material it’s made from. Stainless steel and galvanized steel casings are designed to withstand the pressures and environment of deep-water wells but are susceptible to corrosion. Most steel casings last from 20 to 35 years, on average. PVC casing is highly durable and, if used correctly, can last up to 50 years.
