"I never write reviews, but feel that it is important to help others in selecting a reputable well service contractor. Ben and Grant did a fantastic job in replacing a well pump. What differentiates Hydrocurrent Well Services from the competition is customer service. Unfortunately, the original new pump they installed was defective from the factory and it took them multiple trips to determine that the pump was defective. They kept coming back out to troubleshoot until they figured out the problem and got my well operating again. Highly recommend this company."

"When they came to the house, they were very honest.  I had a plumbing problem that they could’ve easily told me you need to do it now, but they really worked with me and kind of advised me on what I need to do long-term if I couldn’t do the work now and it worked and helped me save a bundle of money.  The quality of the work have always been great."

Wells and Pumps FAQs, answered by experts

Servicing includes cleaning filters and coils, checking coolant levels, and inspecting electrical connections.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

Well pump repair might be covered by your homeowner’s insurance, but it’s typically not. If the damage results from a major storm in your area, flooding, a fire, or some other natural catastrophe, then you should consider filing a claim for the damage. However, if the issue is the result of an aging well pump, your policy will very likely not cover the repair cost. In either case, you should hire a well pump professional inspect your well pump, and then use that information to decide whether or not you should file a claim.

Both can deliver clean water to your taps, but well water and city water carry a few differences. City water is delivered and connected through a main water line, and it travels through a network of underground private and public pipes to service various buildings and structures once it’s been treated.

Well water is derived from dug or drilled wells that source groundwater from the water table. City water is often more expensive than well water, but it eliminates the need for you to test and treat your own well water.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.
