Licensed partner installs

typically $1,800–$5,500 installed

New whole-home systems tie into the main water supply line, which is licensed work (CSLB C-55 water conditioning / C-36 plumbing) and often requires a permit. ADG specs the system, schedules the work and remains your single point of contact; the licence-verified partner contracts directly with you. Any referral arrangement is disclosed in writing.

ADG stays your single point of contact from spec through completion.

Local water

Why it matters in Orange County

Municipal water here runs hard — 15–20+ grains is common. Hard water spots glass, scales fixtures and shortens appliance life. It's the same mineral load we treat on your windows, now handled at the source.

grains per gallon is common in Orange County municipal water

Measured

TDS and hardness recorded before and after every visit

Proof

Before and after, on the meter

Every visit is bracketed by two readings taken at the same fixture. Here is what a typical service looks like on paper.

Whole-house carbon + sediment service

Sample reading

Irvine, 4-bed single family. Cartridges 14 months overdue.

TDS (ppm)
620410TDS went from 620 to 410 ppm
Hardness (gpg)
1811Hardness went from 18 to 11 gpg

Carbon and sediment stages replaced; no softener on site, so hardness drops only partially.

Under-sink RO membrane + filter change

Sample reading

Laguna Niguel, 5-stage RO. Membrane at 3.5 years.

TDS (ppm)
24022TDS went from 240 to 22 ppm
Hardness (gpg)
91Hardness went from 9 to 1 gpg

RO membrane and pre/post filters replaced, tank sanitised. Post-RO tap only.

Softener media + UV lamp service

Sample reading

San Clemente, whole-home softener with UV. Lamp at 19 months.

TDS (ppm)
580470TDS went from 580 to 470 ppm
Hardness (gpg)
203Hardness went from 20 to 3 gpg

Resin media topped and regenerated, UV lamp and sleeve replaced, system sanitised.

How we measure

Readings taken at the kitchen cold tap, run 60 seconds first, water at ambient temperature. TDS by calibrated handheld meter (±2%); hardness by titration test strip read at 30 seconds.

About these figures

Illustrative figures based on typical Orange County municipal water. Your results depend on source water, system type and stage condition — your own before-and-after numbers are recorded on your invoice.
