"My problem was diagnosed the day after I was contacted and fixed the next day! They were professional, punctual, friendly and easy to work with. After the problem was diagnosed, the parts were ordered the same day and as soon as they were delivered the technician was out to fix my booster pump. I would definitely recommend them."

Wells and Pumps questions, answered by experts

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

  • Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

  • Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

  • Have a professional install a water pressure booster pump in your plumbing system.

  • If you experience pressure fluctuations, consider upgrading to a constant pressure system.

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.

If you notice any changes to the water coming from your well, consider that a sign to get a well inspection. For example, if the water is foul-smelling, bad-tasting, cloudy, or discolored, you should call a pro. It’s also a good idea to schedule an inspection if you observe a loss of water pressure, broken equipment, loss of well capacity, or other unusual signs.

If the well pump is more than 10 years old, it's worth contacting a well pump repair pro near you and weighing the cost of repairs against buying a new well pump. Pumps can last a long time with regular maintenance, but if your pump is nearing the 10-year mark and starts needing repairs frequently, it’s time to replace it.

Yes, you can shock a well yourself, but it can be dangerous if you don’t know what you’re doing. We recommend calling a pro, but if you decide to do it yourself, make sure to follow proper safety precautions. This means wearing the correct safety gear, such as rubber gloves, goggles, and boots. You should also mix the chlorine solution in an open area with plenty of ventilation. Also, make sure not to drink or use the water for a few days afterward, until you’ve flushed the system and retested the water.
