"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

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.

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.

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.

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.
