"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

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.
