Reverse Osmosis (RO) Systems

Want cleaner, better-tasting drinking water? MCM Plumbing® installs high-quality reverse osmosis (RO) systems for homes and light commercial spaces in Merced County and the Central Valley. RO removes dissolved minerals, salts, and many contaminants that standard filters can’t touch.

• Under-sink and point-of-use RO systems installed to code
• Licensed A-General Engineering, C-36 Plumbing, and C-34 Pipeline Contractor

We handle everything from sizing and placement to clean installation and startup.

What RO Water Does for Your Home or Business

Reverse osmosis uses a membrane process to reduce many dissolved contaminants, improving taste and clarity. RO is ideal for:

• Drinking and cooking water that tastes clean and fresh
• Reducing mineral content and metallic/chlorine taste
• Families who want consistent, high-purity water at a dedicated tap

RO Systems We Install

We match systems to your needs:

• Standard under-sink RO — the most common option for kitchens
• High-capacity RO — for larger households or higher demand
• Light commercial RO — for breakrooms, coffee stations, or small food service

RO Maintenance & Filter Changes

RO systems need routine service for performance and water quality. We can set you up with scheduled filter and membrane maintenance so you’re never guessing.
