Reverse Osmosis

Provides highly filtered drinking water through a dedicated under-sink system, matched to licensed local plumbers experienced with RO installation.

What Reverse Osmosis Actually Removes

Reverse osmosis (RO) systems force water through a fine membrane that removes a wide range of dissolved contaminants, minerals, and impurities, producing noticeably cleaner-tasting drinking water than standard filtration alone. Most residential systems are installed under the kitchen sink with a dedicated drinking water tap, separate from your regular tap water.

RO water isn’t just filtered, it’s pushed through a membrane fine enough to remove what standard filters leave behind.

When Reverse Osmosis Makes Sense

These situations commonly lead homeowners to RO systems.

  • You want noticeably better-tasting drinking water without buying bottled water
  • A water quality test showed elevated dissolved solids or specific contaminants
  • You’re on well water and want an extra layer of drinking water protection
  • You want RO water specifically for cooking, coffee, or an ice maker
  • Your current under-sink filter isn’t addressing your specific water concerns

What to Check Before Requesting an RO Installation Quote

A little prep helps plumbers install and size the system correctly.

  • Confirm you have space under your sink for the RO tank and filtration stages
  • Decide if you want the RO tap tied to your refrigerator’s ice maker line as well
  • Ask about the specific membrane and filter stages included in the system
  • Ask each plumber about the ongoing filter replacement schedule and cost
