"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 come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

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.
