Water Treatment Services

If your water tastes off, smells like chlorine, leaves hard-water stains, or is damaging appliances, MCM Plumbing® can help. We install and service reliable water treatment systems for both homes and businesses across Merced County and the Central Valley. Every solution is sized to your demand, your plumbing layout, and your water-quality goals — not a generic “one box fits all” setup.

• RO systems, softeners, conditioning, and whole-house filtration
• Licensed A-General Engineering, C-36 Plumbing, and C-34 Pipeline Contractor

We start with a practical evaluation of your water concerns, usage, and available install locations. Then we recommend the right system for performance, comfort, and long-term reliability.

Why Water Treatment Matters

Central Valley water often contains minerals and residual disinfectants that can cause everyday problems. A properly designed treatment system can:

• Improve drinking-water taste, odor, and clarity
• Reduce hard-water scale that damages water heaters and fixtures
• Minimize staining on sinks, showers, and toilets
• Help soap and detergent work better
• Extend the life of appliances and plumbing

Signs You May Need Water Treatment

If you’ve noticed any of these, we can help you pinpoint the cause:

• White spots on dishes, glass, or faucets
• Dry skin, dull hair, or soap that won’t lather
• Metallic taste, chlorine smell, or cloudy water
• Rust stains or orange/brown discoloration
• Repeated appliance failures from scale buildup
