"John was fantastic. It was a job that did not go as easily as it should have but John handled it so well and was prepared for any thing that did not go well. He came fully prepared to make sure we would have hot water at the end of the day! The professional service is very much appreciated I will be glad to refer his company and am planning to have him back to fix a faucet soon."

"Was having a problem with well pump cycling on and off too frequently.  They came out right away. Checked the control box, pressure gauge and pressure tank. I thought they were going to have to pull and replace the pump which is big $$$. He said lets looks for leaks in your system 1st.  No problems inside but he used a stethoscope on my 4 outside faucets and heard a small below ground leak. Adjusted by valve on the unit and said that should do it!  On site almost two hours and only charged a trip charge (60 miles one way for them in big truck couldn't have been cheap)... no additional labor, etc. They were great! Definitely recommend them for their honesty and thorough diagnosis instead of just throwing parts on an unknowing customer.

I bought a chimney sweep big deal and it went well. It cost more than the price of the big deal due to the repairs they made. The guys that did it were just a little bit weird. They were kind of socially awkward. They had some difficulties communicating.

"Went well to this point of replacing parts. Then the United needed to have a system leak test and then needed freon put in pump. This was refused by Choice warranty. We were left with a partial repair and a heat pump not able to do it's job."

"Dale is terrific. I was immediately impressed by his knowledge of my situation, and felt like I had a partner in figuring out what needed to be done. I was on borderline warranty situation so he helped me advocate for a replacement by the company (which ultimately didn't work, but that's only because Zoeller is tight on their warranty policy). Realizing I needed to replace the pump, Dale only charged for an installation and not for the diagnosis. That was helpful. He found a way to get us up and going quickly, even though he had other jobs underway. I was really pleased with the work. If you have a problem with your sewer lines, septic or any pump systems, Dale at HS Sewer & Drain is the guy to call. I have no doubts about making that recommendation."

"I have been with AHS since 1999 and have used them 4 times: dryer belt broke, dishwasher leaked, heat pump quit working properly, and dryer stopped working. Yes, it is frustrating to wait on hold for a long time, but I have been pleased overall with the service provided. They subcontract the work out, and in the case of the dryer, the guy did not know how to fix the problem and left. AHS followed up immediately with another provider, who had fixed my first dryer problems 8 years ago, and was very knowledgable and did an excellent job. Service charge is standard $75. I have an annual maintenance plan for my heating/cooling systems with a heating company and when they came out this past fall, they found a problem with the heat pump and quoted the fix at $2,000 plus. I called AHS and they confirmed my heat pump was covered under the warranty and sent someone out the very next day. They immediately fixed the problem and I paid them the $75 service fee. Thus far, I have had good experiences and will continue my annual plan with them."

Wells and Pumps FAQs, answered by experts

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

If you have a small well or a particularly high water demand, it’s possible to overuse your well. How quickly a well replenishes depends on its water source. In this case, you may want to purchase a water storage tank that you can fill from the well in off-hours, or if you’re planning to build a new well and you expect a large water demand, you may want to build a deeper well to match your needs.

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.
