"Maine septics put in a system for one of my clients, and they did a fantastic job. Everyone else we talked to quoted us much higher, or couldn’t get it done for months. These guys get it done!"

"I found Caldwell Septic and Drains on Angi. He got in touch with me the day I posted my inquiry, and we quickly scheduled time for him to come out. We had two lines from our bathroom clogged and Zach came out and fixed both quickly. He explained what he needed to do and was professional. He then explained the invoice to me and thanked me for my business. I’d definitely recommend Caldwell Septic and Drains and will be using them in the future."

Septic Tanks questions, answered by experts

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

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. 

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.
