"The service technician was 2 hours late and his price was $1900, I decided to get a second quote and I am so glad I did. I got the same job done with better tank and filter for $1100. My advice is get a second quote if you have time, I saved $800 by using another company."

Septic Tanks questions, answered by experts

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

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.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.
