"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 questions, answered by experts

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

Many contractors offer warranties for parts and labor. Confirm terms before hiring.

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.

DIY is not recommended due to safety and technical requirements. Hire professionals for accurate diagnosis and repair.
