3-Stage Pre-Filter + Softener + FREE Reverse Osmosis

3-Stage Whole-House Filter · Water Softener · 5-Stage RO Under-Sink System

The most complete city-water package. The 3-stage pre-filter removes Houston's chloramines before they reach the resin bed, extending softener resin life and improving overall water quality.

Pricing by System Size

Grain	Flow	Household	Price
32,000	7 GPM	1–2 bath · 1–2 ppl	$2,789

What's Included

Salt-based water softener (Fleck 5600SXT) — sized to your home
3-stage whole-house cartridge pre-filter system
Stage 1: Sediment — removes sand, rust, silt, and debris
Stage 2: Carbon Block — removes chlorine, chloramines & VOCs
Stage 3: KDF-85 — reduces iron, hydrogen sulfide & heavy metals
5-stage RO under-sink drinking system included
Cartridge replacement every 4–6 months

Why the pre-filter matters: Houston city water contains chloramines — more damaging to softener resin than standard chlorine. The 3-stage pre-filter removes chloramines before they reach the resin bed, extending resin life significantly.

Well Water: 3-Stage Pre-Filter + Softener + AIO Carbon Tank + FREE RO

3-Stage Pre-Filter · Well Water Softener · AIO Catalytic Carbon Tank · 5-Stage RO System

Minimum 48,000 grain — well water requires a larger system due to iron content and higher hardness loads. Includes free well water test before install.

Pricing by System Size

Grain	Flow	Household	Price
48,000 Min	10 GPM	2–3 bath · 3–4 ppl	$3,489

80,000	15 GPM	4–5+ bath · 6+ ppl	$4,389

48K minimum for well water · final size set after free well water test · 1-yr warranty

What's Included

AIO iron & sulfur filter — removes up to 7 PPM iron, 2 PPM manganese, and hydrogen sulfide. Fully automatic backwash, no chemicals required.
Fine mesh resin softener (Fleck 5600SXT) — fine mesh resin required for well water; handles residual iron that standard resin cannot
Sediment pre-filter — removes sand, silt, and debris before iron filter and softener
Sized to your home — see sizing chart on page 3
5-stage RO under-sink drinking system included
Free well water test (iron PPM, manganese, sulfur, hardness GPG, pH) before system recommendation

What it removes: Iron (up to 7 PPM) · Manganese (up to 2 PPM) · Hydrogen sulfide / rotten egg odor · Hardness minerals · Sand, silt, sediment · Heavy metals · Taste and odor issues

Why well water is different: Standard softener resin cannot handle iron above 1 PPM — it fouls the resin and causes early failure. The AIO iron filter removes iron, manganese, and sulfur before the water reaches the softener. This configuration is designed for well water with elevated iron, manganese, or sulfur levels.

10 GPM	2–3 bath · 3–4 people	$3,489

Salt-free vs. salt-based: Does not add sodium to water. Hardness minerals remain present in a non-scaling crystal form. Water will not have the same feel as salt-softened water.

Suitable for: Homeowners who want to avoid salt maintenance, live in areas with brine discharge restrictions, or prefer to retain minerals in their water.
