"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

Yes, you can shock a well yourself, but it can be dangerous if you don’t know what you’re doing. We recommend calling a pro, but if you decide to do it yourself, make sure to follow proper safety precautions. This means wearing the correct safety gear, such as rubber gloves, goggles, and boots. You should also mix the chlorine solution in an open area with plenty of ventilation. Also, make sure not to drink or use the water for a few days afterward, until you’ve flushed the system and retested the water.

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

Repairs typically take 2-4 hours. Complex issues may require additional time.

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle.
