"Highly recommend. They were very quick to come out and provide an estimate. They offered quotes for both parts replacement or full replacement of our UV light system. The other 2 companies we asked would not give us quotes to replace the broken part. Maine's Best Water Treatment was also the most inexpensive of the quotes we received. They were very responsive to texts and provided accurate times of arrival. They were very professional. After the install, there was a mix-up where my husband told them we didn't need a water sample test but because of a pending house sale, we were required to have one. They were very understanding when I asked if they could come back out to sample our water. I would highly recommend working with them. They went above and beyond."

FAQs for water treatment & purification system installation and replacement projects in Caribou, ME

In a reverse osmosis system, water from your main line—or from a designated faucet—is pushed through a semipermeable membrane under pressure. The membrane’s microscopic pores trap dissolved solids, heavy metals, and other contaminants, while clean water passes into a storage tank or straight to the tap. The leftover concentrated water simply drains away. The result is clear great-tasting water delivered right where you need it.

A plumber can set up a point-of-use unit in one to two hours. A whole-house system is more involved and can take one to two days because it ties into the main supply line and may require extra plumbing. During installation, the pro mounts the unit, connects the pipes, checks for leaks, and tests performance so you’re ready to pour a glass as soon as they leave.

Reverse osmosis removes dissolved solids, heavy metals, and microorganisms, giving you water that tastes cleaner. Softer water also helps appliances, faucets, and ice makers last longer. Because you’re filling reusable bottles instead of buying single-use plastic, most homeowners save money and cut down on waste. In short, you get better-tasting water, longer-lasting appliances, and a smaller environmental footprint from one straightforward system.

Reverse osmosis filters have a defined lifespan and must be replaced regularly to maintain water quality. Point-of-use systems deliver peak performance for six months to one year before the filters require changing, while whole-house systems need replacement every three to six months. Adhering to these intervals maintains the system’s efficiency and ensures that your water remains safe for consumption. Routine maintenance by a qualified professional keeps the filtration system operating at its best.
