If you’re building a new home in an area without access to a city sewer system, you may need to install a septic system. If you’re experiencing consistent problems with your existing septic system, it might be time for a repair or replacement. An inspection can help further diagnose the issue, but here are five questions to ask about septic systems when you talk with a pro. 

1. What type of septic system problems are you having?

When you experience plumbing issues across multiple fixtures in your home, it usually indicates a septic system problem, not a clogged drain. You might notice slow drains, gurgling pipes, foul odors, sewage backup, and standing water when your septic system is on the fritz. Be ready to share the list of issues to help your septic system pro understand the problem and the tools needed to fix it. 

2. When do you need this work done?

Contact a local septic tank pro immediately if you notice sewage backup, foul odors, or frequent slow drains. Delaying a septic tank repair can lead to expensive water damage, sewage leakage into your home, basement flooding, and cracks in your foundation. 

If you’re installing a septic system for a new home, a pro needs to excavate, grade the land, and install the system. Contact a septic tank pro early in the build process, and be sure they coordinate with your general contractor. 

3. What kind of septic system is this? 

There are several types of septic systems, each with its own pros, cons, and costs. Research the options and discuss them with your pro. Conventional septic systems are the most common, but you might consider a chamber system or aerobic treatment unit. Your property’s proximity to bodies of water can also impact which system to install. If you’re unsure what type of septic system to choose, ask for recommendations from your pro.

4. When was the last time you pumped your septic tank? 

You should pump your septic tank once every three to five years. If it’s been longer than that, you might need a cleaning instead of a repair or replacement. Describe your last septic tank pumping and any maintenance you’ve had so a pro can determine the best services.

5. What is your budget for your septic system? 

For most homeowners, installing a septic system costs $3,620 to $12,410, depending on materials, labor, and the type of system. Before you dig in, get at least three quotes from licensed professionals. 

If you have septic system issues, prepare for the expense of fixing your septic tank. Septic tank repair costs often fall between $630 and $3,040, with new lids and filters falling on the lower end and a new tank or pump on the higher end.
