"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.

"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

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.

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.

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.

Well pumps need power to run, so they can’t function without electricity. If your power shuts off, there can sometimes be enough pressure in the water tank to allow for a lucky flush or a bit of tap water—but this won’t last long. It’s a good idea to have a backup generator or an alternative power source like solar if you’re worried about losing power.

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.
