Reverse Osmosis Installation & Maintenance · Los Angeles & SoCal
Bottled-water taste from your own kitchen tap.
Under-sink and whole-home RO installed, serviced and filter changes on schedule.
Reverse osmosis pushes water through a membrane fine enough to leave most dissolved solids behind — the chlorine taste, the scale minerals, and dissolved metals like lead — so the water you drink and cook with is the cleanest in the house. It's the one step a whole-home softener can't do for you.
An RO system only performs as long as its filters and membrane are changed on schedule and its drain line and pressure are right. We size the unit to your household and tap demand, plumb it with its own drain and shut-off, and keep it running: filter changes, membrane care, tank sanitizing and leak checks — booked for you instead of remembered by you.

Reverse Osmosis Installation & Maintenance: common questions
Do I need reverse osmosis if I already have a softener?
They do different jobs. A softener removes the minerals that cause scale; reverse osmosis polishes the water you drink at one tap. Many homes run a softener on the whole house and RO at the kitchen sink.
How often do RO filters need changing?
Sediment and carbon pre-filters are usually changed about every six months, and the membrane and final filter about yearly, depending on your water. We set the schedule from your water and usage so the system never quietly drops off its performance.
