Septic Tanks FAQs, answered by experts

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

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.

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900.
