"I called and setup an appointment for the afternoon.  The dispatcher called back in an hour saying the plumber was free earlier and came immediately.  He was there within an hour and gave me an estimate for the replacement and upgrade that I wanted.  I agreed to the price and within 3 hours I had a new water heater.  I can?t imagine where they could have done any better.

"Fair prices and great quality of work. I received a couple quotes from different plumbing companies to replace my old tank water heater for a new tankless water heater. Most companies were charging an arm and a leg for what I was asking, however lifeline water heating gave me a great price and they included 2 years of free maintenance!! Strongly recommend this company."

Wells and Pumps FAQs, answered by experts

No, a larger well pressure tank will not increase or improve water pressure on its own. The pressure control on the well pump is what determines the water pressure in your home. However, a larger tank does offer other benefits. It can hold more water, allowing you to run it for longer before the pump needs to turn on. Because the pump cycles on and off less frequently, there is less stress and wear on the well system. This can lead to a longer lifespan for the pump and tank, and you may experience fewer pump-related issues that could affect your water pressure in the long run.

If you want to increase your water pressure, you can try one of the following solutions:

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

• Replace your current pump with one that has a higher flow rate (GPM).

• Install a water pressure booster pump in your plumbing system.

• For pressure fluctuations, consider replacing your current setup with a constant pressure system.

Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.

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.

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.

The Centers for Disease Control and Prevention (CDC) recommends testing your well at least once a year to check for bacteria and contaminants. If you live in an area prone to flooding, runoff, or any other environmental concerns, it can be a good idea to check two to three times per year.
