"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Septic Tanks FAQs, answered by experts

They can if they’re not installed correctly or if the caps or covers were dislodged by a lawn mower or other yard equipment. This is why it pays to hire a reputable septic tank company that’s experienced in septic tank installation and maintenance. You should also check caps and covers often to see that they’re in place and take measures to tighten or secure them, provided it is safe to do so.

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

There are a few signs that you might notice if your drain field is bad. For starters, if you see standing water or soggy grass above your drain field, it could mean that it isn’t working correctly. Or, if your yard smells like sewage, it could also indicate that there’s a problem with your drain field. Repairing a drain field costs an average of $2,000 to $15,000.

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.
