"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks questions, answered by experts

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

Neither system is necessarily better or worse than the other, but one of the two might be better for your needs. For example, anaerobic systems are less expensive than aerobic ones and don’t use power to run. On the other hand, aerobic septic systems don’t take up as much space and are typically more efficient than their anaerobic counterparts.

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.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more.
