"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

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.
