Why Valley homeowners pick Signature
Phoenix Valley homes often deal with hard water scale and municipal disinfectant taste at the same time. Softening alone will not fix pool-like drinking water. Kitchen RO alone will not stop spots on every shower door. Signature treats both: whole-home stages at the main line, tankless RO where you drink and cook.
This is our most-requested configuration when assessment shows both hardness and drinking-water priorities. Capacity, media, and kitchen layout are confirmed before install—no fake reviews, no invented NSF certificate numbers, and no pressure pitch.
Stage A
Whole-home softener & filtration
Point-of-entry treatment sized for residential flow, with softening resin for hardness and coconut-shell carbon for chlorine taste and odor concerns common in Phoenix Valley municipal water.
Granular activated coconut-shell carbon
Carbon media selected for chlorine and chloramine-related taste and odor treatment, with capacity oriented toward longer service life when maintained as directed.
USA-made high-capacity softening resin
10% crosslinked softening resin designed to remove hardness minerals and support high-flow soft water with attention to chlorine durability per manufacturer literature.
Polishing gravel bed
Supports even flow through the media bed and helps reduce channeling so softening and filtration media work as designed.

Seven-stage under-sink drinking water treatment for the kitchen. Tankless footprint, alkaline remineralization stage, and high daily production rating per manufacturer literature.
Stage 1
Sediment pre-filter
5-micron polypropylene sediment stage to capture suspended particles before carbon and membrane stages.
Stage 2–3
Dual carbon block
Double carbon block stages (manufacturer-listed NSF carbon blocks) to address chlorine by-products and prepare water for the RO membrane.
Stage 4
800 GPD RO membrane
High-rejection thin-film composite membrane rated at 800 GPD in manufacturer literature, intended to reduce dissolved solids and a wide range of impurities at the drinking faucet.
Stage 5
Coconut-shell GAC polish
In-line granular activated carbon stage for taste and odor polishing of product water.
Stage 6
Alkaline remineralizer
Internal alkaline remineralization stage to improve drinking-water taste and balance after RO purification, per manufacturer description.
Stage 7
Final GAC polish
Additional in-line coconut-shell GAC stage for dissolved gases, taste, and odor before the dedicated drinking faucet.
- Seven-stage design
- 800 GPD rated production (manufacturer literature)
- Tankless under-sink footprint
- Alkaline remineralization stage
- Brochure-listed high rejection of dissolved solids
Contaminant reduction details depend on the exact installed model and certification listing. We do not invent NSF certificate numbers or home-specific reduction percentages—those are confirmed during assessment when the SKU is verified.

No. Signature pairs whole-home hardness and taste treatment with dedicated kitchen RO. Softener-only homes that mainly fight scale can start on the softener path instead.
Only after the installed model and certification listing are verified. Manufacturer literature describes membrane performance; we do not invent home-specific percentages or fake reviews.
