Hard water contains dissolved calcium and magnesium minerals measured in Grains Per Gallon (GPG). Anything above 7 GPG is considered hard. At 18 GPG, Houston homeowners deal with nearly three times that level every day — silently damaging appliances, drying out skin and hair, leaving scale on fixtures, and shortening the life of water heaters and plumbing. A professionally installed water softener eliminates these problems at the source.

How a Complete System Works

Water enters your home, passes through each stage in sequence, and comes out clean — everywhere.

System Diagram
① 3-Stage Pre-Filter
Water enters the home and passes through three cartridge stages: Stage 1 sediment removes sand, rust & debris. Stage 2 carbon block removes chlorine, chloramines & odor. Stage 3 fine filter removes remaining particles. Protects every downstream component.
② Catalytic Carbon AIO Tank
An air pocket at the top oxidizes contaminants; catalytic carbon media then filters them out. Removes chloramines, VOCs, light iron & hydrogen sulfide. Self-backwashes 1–2× per week automatically — no cartridges, no user action. Media lasts 7–10 years.
③ Water Softener
Ion-exchange resin beads swap calcium & magnesium (hardness minerals) for sodium. Eliminates scale on fixtures, appliances & plumbing. Fleck 5600SXT control valve meters usage and regenerates automatically using salt from the brine tank. Soft water flows to every tap in the home.
④ Brine Tank & Regeneration
The brine tank holds salt pellets used to recharge the resin bed. During regeneration, brine flushes the resin — displacing trapped hardness minerals down the drain line. Holds 250–300 lbs of salt; refills approximately every 6–8 weeks. We show you exactly how before we leave.
