"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

Well water can taste different depending on the underground water source it taps into. Some well water tastes slightly sweet, while some may have a slight odor or no taste at all. If you find that you don’t like the taste of well water, a simple drinking water filter can remove most taste and smell.

Reduced water pressure, strange noises, or air sputtering from faucets.

Both can deliver clean water to your taps, but well water and city water carry a few differences. City water is delivered and connected through a main water line, and it travels through a network of underground private and public pipes to service various buildings and structures once it’s been treated.

Well water is derived from dug or drilled wells that source groundwater from the water table. City water is often more expensive than well water, but it eliminates the need for you to test and treat your own well water.

The average lifespan of a deep well pump is between 15 and 25 years, after which you’ll have to replace it. Several factors can affect the lifespan of a well pump, such as the quality of the unit. Proper maintenance and repair can also help extend your well pump’s lifespan as well as keep adequate water flow and pressure throughout your home.

Schedule annual inspections, test water pressure, and protect the pump from freezing temperatures.
