"They are family owned and operated. Jorge was very friendly and professional, and did everything to help. They even moved the tops of the tanks that must have been over a hundred pounds to a different location and installed Risers. We had to find where the septic tanks were, and what type of tanks, and what was needed to bring the tanks up to code. So we can sell the property. We would recommend them to anyone."

Septic Tanks FAQs, answered by experts

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.

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.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.
