"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

DIY is not recommended due to safety and technical requirements. Hire professionals for accurate diagnosis and repair.

Consider site conditions, soil type, required capacity, and system designs compatible with environmental protection regulations.

Common problems include low water pressure, no water, and strange noises. Regular maintenance prevents many issues.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue.
