"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks questions, answered by experts

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

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.
