"Sorry, looks like this review got stuck in draft mode for quite a while. But the good thing about that is everyone gets to read a review with an update 1.5 years later on the quality of the work completed! In late 2020 I had recently moved into my new home and the gas water heater wasn't working properly. It was leaky and at least needed the pressure relief valve replaced, but the tank was well past it's expected lifetime. The techs were very helpful, kind and knowledgeable. The valve replacement wasn't going to work because repairing the tank could damage it further, so the tank was replaced instead. The price was very reasonable and installation was done really well. They did a great job with cleanup too! One and a half years later and the tank has had zero issues! I would definitely recommend them for heavy jobs like this or more simple ones around the house. Thank you very much!"

Septic Tanks FAQs, answered by experts

Yes, a septic tank can get full. If this happens, you might run into issues flushing your toilets or draining your sinks. You may also notice your pipes making gurgling noises or the smell of sewage floating around your house. Other signs of a backed-up septic tank include water pooling or fresh, healthy grass growing above your drain field.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

A septic system inspection costs $100 to $200. Doing so can spot issues early so you can plan for necessary repairs ahead of time and save yourself the issue of a backed-up septic tank. Some septic tank repair professionals do an inspection as part of their yearly maintenance on your septic tank if you choose to pay for that service, but you should shoot to have a septic system inspection completed at least once every two to five years.
