"Fred's was professional and their office manager, Angie, was on top of everything, including following up with me and letting me know that they did in fact leave a message for my client (I am a realtor who recommended them for a home sale well/septic inspection prior to closing). They offer a bundled rate for performing these 2 tests simultaneously. Very happy with the servicing and handling of this transaction."

Septic Tanks questions, answered by experts

By keeping up with regular maintenance and inspections, you can expect your septic system to last 20 to 40 years. You need to have a pro pump your system every three to five years, depending on how much water your household uses. Always call a pro at the first sign of any potential trouble to increase the life span of your system.

Septic tank costs vary with the size of the tank—and the size you need depends on the size of your household. For example, a 1,000-gallon septic tank is the minimum size for most 1-, 2-, or 3-bedroom homes, and costs between $900 and $1,500. However, the tank is only one part of the septic system—which costs significantly more to install. If you’re setting up a new septic system (rather than replacing an existing tank), you can expect to pay about $7,310 on average. Costs can be higher depending on the type of septic system you choose.

A septic tank needs to be pumped once every three years on average. However, every septic tank has different needs, and the proper service interval for your system may be every five years, or as frequent as an annual pump-out. Consult with your installer about the proper interval and what to expect regarding the cost of septic tank pumping.

The average three to four-bedroom home uses a well pump of 8 to 12 GPM. It’s recommended to calculate your own GPM based on the number of water fixtures in your home so you can find the pump size that’s most accurate to your needs.

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home.
