"Marcus came over the day after I requested the quotes (quotes requested Sunday, he came Monday.) He assessed the situation and explained options and pricing. He very willingly attempted the lower cost option first, even though we had doubts it would work. He told if it did not work and we had to go to the higher cost option, I would only be charged for that, not both. We did have to go to that option and he was able to clear the clog from my sewer line. He then inspected with a camera and showed me that there were several roots intruding on the line. He recommended repeating the process with a nozzle designed to remove these. He did not have that on his truck, so another visit was scheduled for today with a different tech. This was also successful and it was clear from the camera inspection at the end that the roots were gone. I was expected a horrible mess from this process, and was very happy that both operations were completed with minimal additional sludge in my basement."

Wells and Pumps questions, answered by experts

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.

Some states and municipalities restrict well pump repair and replacement to licensed plumbers and technicians, while others don’t have requirements. However, it’s always a good idea to hire a certified plumber to repair or replace well pumps and water pumps. Certified professionals are far more likely to get the job done correctly and prevent future issues, which is especially important for ensuring access to clean water for your home.

Here are some signs of a bad well pump that a pro should look at: 

  • If your well pump isn’t pumping water, you could have a leak or malfunctioning pump on your hands. 

  • If your water pump runs nonstop, there might be a leak or problem with the pressure tank, which can cause the pump to fail. 

  • Low water pressure can happen because of your pressure tank, low-water levels, or a wrong-sized pump. 

  • Dirt or sediment in your water can be a problem with a powerful pump, damaged pump filter, or the pump’s location.

The average three to four-bedroom home uses a well pump of 8 to 12 GPM. It’s recommended to calculate your own GPM based on the number of water fixtures in your home so you can find the pump size that’s most accurate to your needs.

There are other ways to increase well water pressure. You can often increase the pressure by adjusting the valve on your pressure tank. The pressure issue may be the result of build-up along the pipes or a clog in the system, so descaling and unclogging your system can help improve the overall pressure.
