"Anthony Fankhauser (Owner) is an exceedingly polite individual who provided detailed information on work to be accomplished. Unfortunately, the day my septic tank was being pumped coincided with a number of issues Anthony was experiencing on another job. For that reason, my task was delayed until after 6:00 PM. When Anthony arrived late in the evening to complete the work, he performed camera inspections and explained some minor issues. There was no indication of irritation or frustration due to the issues related to his other task. This was refreshing since I sincerely expected him to vent regarding problems experienced with his other work. I seriously recommend using Anthonyâ s services if you have plumbing issues."

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"I have used Rossman Plumbing several times and they are an excellent company. They replaced my shower valves and repaired again lime water leak. They showed up on time, kept me informed of the work, photographed the work before and after and stayed within their proposal. I have never had an issue with them. Wally C"

Septic Tanks FAQs, answered by experts

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

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.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.
