Wells and Pumps questions, answered by experts

Well water can taste different depending on the underground water source it taps into. Some well water tastes slightly sweet, while some may have a slight odor or no taste at all. If you find that you don’t like the taste of well water, a simple drinking water filter can remove most taste and smell.

Consider replacement if the pump is over 10 years old or has recurring, costly issues.

Schedule annual inspections, test water pressure, and protect the pump from freezing temperatures.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.
