"When they came to the house, they were very honest.  I had a plumbing problem that they could’ve easily told me you need to do it now, but they really worked with me and kind of advised me on what I need to do long-term if I couldn’t do the work now and it worked and helped me save a bundle of money.  The quality of the work have always been great."

"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

Many pros offer rapid response services to restore essential water flow quickly.

You should check water pressure twice a year to ensure there aren’t any irregularities and that it isn’t too high. It’s also smart to check it any time you notice symptoms of high water pressure (like banging pipes, inconsistent water flow, and leaky fixtures). Similarly, if you live in an area that’s prone to water pressure fluctuations due to municipal supply changes, elevation, or seasonal temperature shifts, check it more frequently. You can buy an affordable water pressure gauge and check the water pressure yourself.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

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.
