Mrs. WaterWater Filtration

Hard water

Hard water is quietly
costing you appliances.

Scale builds up inside your water heater, your dishwasher and your washing machine long before you can see it on the fixtures. A whole-house system costs less than the appliances it saves.

What hard water actually does

Houston water carries a heavy mineral load. Every time it's heated, some of that mineral drops out and stays behind — on the heating element, in the pipes, across the inside of every appliance that touches hot water.

And the part you feel

Houston adds chloramine — chlorine combined with ammonia — to disinfect the water supply. It's what you smell in the shower, and it's a common reason skin and hair feel dry and tight afterwards.

This is where KDF comes in. KDF is the filtration media best suited to Houston's water. It targets chlorine and chloramine specifically, which a generic carbon cartridge does not do nearly as well. It's the reason our systems are built the way they are.

The system

Three stages at the main line, so every tap in the house is covered — better water for drinking, bathing, cooking and cleaning, and longer life out of your appliances.

  1. Sediment — sand, silt and grit
  2. KDF — chlorine and chloramine
  3. CTO carbon — taste, odour and organics

Three-stage system with descaler — filtration and scale protection together. This is what we recommend for most Houston homes.

Filtration on its own is $2,595. Adding the descaler at the same install is $400 — less than doing it later, because the plumber is already on site.

Both prices are the standard install on a 1" PVC line by a licensed master plumber, with a one-year warranty on parts and labor, insulation for freezing weather, and a bypass so servicing never shuts off your water.

Which one do you need?

If hard-water buildup is what's bothering you — spots on the glass, a crust on the fixtures, appliances wearing out early — you want the descaler. If it's the smell in the shower or dry skin, filtration alone solves it.

Why the descaler can't go in alone. A descaler only works with a filter ahead of it — without one it clogs. You'll see standalone descalers advertised elsewhere; that's why we don't sell them that way. It's an addition to the filtration system, not a replacement for it.

Already have a system from us? A descaler can be added at your next filter service. Ask us when we're out.

Water line 1.5" or larger? You need a high-capacity system instead — a standard unit can't keep up with the flow. See high-capacity systems →
