"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

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

Yes, it is possible to pump a septic tank too frequently. The ideal pumping schedule varies based on the tank's capacity, household size, and water usage. Pumping the septic tank more often than recommended can cause the beneficial bacteria to leach into the drain field, leading to an imbalance and a build-up of solid waste.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

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.
