"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

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.

If you have a well-related issue, such as your well water stopping, you should hire a local water well contractor or a well and pump repair professional. These specialists handle all aspects of wells, including the pump, tank, and other outdoor water pumping equipment. They can inspect your system, recommend and perform repairs, and even coordinate a water quality test if needed. While plumbers are experts in indoor plumbing, they may not have the specialized experience with residential wells that a dedicated well contractor does.

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

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. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

A professional well inspection takes between one and three hours. This includes the time it takes for the inspector to visually check the condition of your well, test its equipment, and collect water for testing. After the pro sends the water samples to the lab, you can expect to receive the results in three to 10 days.
