"The service people came quicker than expected, they were pleasant enough and did identify a small filter that needed rinsing and they identified it quickly. I'd give them an A on that part but the cost they charged is an F rating. They took a regular bottle of drinking water and poured it through the filter, put the filter back in and they were done. Then they charged me over $540 for this. They did absolutely nothing else and when I asked why it was so expensive, they said the travel time. I am 30 minutes from their area. When I first spoke to the owner, who was not the one who came out, he never said there would be an extra charge for my location. The fix was so minor, the time spent was maybe 15 minutes and they overcharged me. If you use them beware of their very high charges."

Wells and Pumps questions, answered by experts

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

You should have your well inspected once per year. You should also have a well inspection done when you’re buying a house with a private well, when the well cap is opened, when the septic tank is repaired, or when there is flooding.

During your annual visit, a pro will make sure that everything is working correctly and check for certain contaminants, including total coliform. Every other year, they’ll look for things like metals and nitrates, and every five years, they’ll test for pesticides.

The right psi for your well pressure tank depends on the tank’s pressure settings. For instance, if yours is set to 30/50 psi (which is common), the ideal psi is 2 to 3 psi below the cut-on pressure—in other words, 27 to 28 psi. However, if it’s at a higher setting of 40/60 psi, 38 psi would be the appropriate level.

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

When testing the pressure of your well tank, the psi should be two below the cut-on pressure. For example, if your tank is set to 40/60, then your pressure should be at 38 psi.
