"Two service Techs, Daniel and Kevin, came by the same day i called regarding a clogged sewer line. They were very pleasant and personable which put me immediately at ease. They performed an inspection and showed me a live video feed of my sewer line, indicating where the roots were growing in that caused the clogging.
They recommended hydrojetting due to the size of sewer, and scheduled a visit the following day. The next day the same techs came by and cleaned out the sewer line via hydrojetting. Afterwards they did another video inspection and showed me their results. They were professional, communicative, clean, and very pleasant to deal with.

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.

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.

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.

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.
