"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

Every 1-2 years to ensure optimal performance and prolong lifespan.

Yes, professionals can replace worn-out motors to restore efficient airflow.

Yes, you can oversize a well pressure tank without harming your well system, as there are no major risks involved. The primary advantage of a larger tank is an increased lifespan due to less frequent pump cycling. Fewer startups and longer, slower runtimes mean less wear and tear on the system and can help conserve energy. The main drawbacks are the higher upfront cost and the larger amount of space required for an oversized tank. While not necessarily a bad thing, it is often more efficient to select an appropriately sized tank to save money and space.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

Servicing includes cleaning filters and coils, checking coolant levels, and inspecting electrical connections.
