TDS Explanation

TDS (Total Dissolved Solids) indicates the amount of dissolved minerals and salts present in water. The right filtration setup helps reduce excess TDS and improve taste, odor, and overall water quality based on source-water conditions.

Installation

Our team provides on-site installation, pressure and leak checks, flushing, and final performance testing. Proper installation ensures stable flow, safe operation, and long service life of the filtration system.

FAQ

How often should filters be replaced? Replacement intervals depend on usage and feed-water quality; periodic service checks are recommended.

Do you provide maintenance support? Yes, we offer maintenance and service support plans for residential and commercial installations.
