"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

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

A septic tank should be pumped once every three to five years or sooner if there’s a problem with your plumbing backing up. A large 5+ person family who frequently has guests over using the bathroom or who pours a lot of water and food down the garbage disposal may need to get it pumped closer to every two years.

If you’re maintaining your septic system, your drain field should last around 20 years. However, it’s important to get it inspected every two to five years to help your system last as long as possible and make sure it’s in safe, working order. Contact a septic maintenance company in your area for a quote.

The cost to drill a well varies, but the national average is around $5,500 for a 150-foot well. However, prices can vary significantly based on location, well depth, and other factors, so it's best to research potential fees to get a more accurate cost assessment for your area.
