"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 FAQs, answered by experts

Septic tanks appear full after pumping because the liquid levels have returned to normal. If you can see the pipe, the tank is empty. However, heavy rain can cause septic tanks to fill faster than normal. You might also have leaky pipes or faucets, causing extra water to drip down the drains and into the septic tank.

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.

Common signs that your well pump is failing include fluctuating or consistently poor water pressure, sputtering water from faucets, or a complete loss of water. Other indicators are unusual noises coming from the pump, the pump running continuously, dirty or cloudy water, or a sudden, unexplained spike in your utility bills. While some issues, especially after a power outage, might be resolved by simply restarting the power or priming the pump, persistent problems suggest a more serious issue. If you notice any of these red flags, it is recommended to call a professional well pump service to inspect the system and determine whether it needs to be repaired or replaced.

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.
