Water treatment & purification system installations and replacements FAQs

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 often takes one to two days because it ties into the main supply line and may need 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 many microorganisms, giving you water that tastes cleaner and protects your family. 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 waste. In short, you get better‑tasting water, longer‑lasting appliances, and a smaller environmental footprint from one straightforward system.
