"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

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

Yes, it is possible to drill a well by hand, but it calls for a good deal of physical labor. Drilling a well by hand is best suited for softer soil, and it may not be possible through rockier terrain. For wider and deeper holes, companies with professional equipment make the job much easier.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.
