"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."

"My existing hot water heater (12 years old) would not relight and had exhibited signs of tank failure (some discolored water and slight leak). I contacted a few vendors and NE Renovations met my budget and schedule constraints. I made the initial call the evening of December 28 and received a quick response from Richard Froais. The site survey and quote were received on December 29 with the installation taking place December 30 morning.

The installation crew, Jim and Randy, were punctual, courteous and thorough, and cleaned up the site well. It was a pleasure to work with them and NE Renovations.

Of particular note, my previous installation had some errors in the piping which were not apparent until a few years later. I related these symptoms to Richard and Jim who figured out the situation and agreed that it could be fixed as the new tank was installed. This I expect will create better operating conditions and longer life."

Septic Tanks FAQs, answered by experts

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

There are a few signs that indicate a failing drain field. For instance, if your septic tank starts requiring more pumping than normal, your drain field might be failing. Other signs to watch for include poor drainage after rain, standing water or sewage over the septic system, a strong septic smell outside, new and healthy grass growing over the drain field, and plumbing backups in your sinks, bathtubs, or toilets.

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.

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.
