Test Water
On-site test for hardness, iron, and other contaminants.
Size & Plumb
Size media to test results, plumb bypass and filter bank.
Post-Test
Test after installation and hand you the cartridge schedule.
Hard water and iron differ street by street in this city, which is why sizing starts with a test, not a brochure: rust stains in the basin, scale crust on taps, well-water sediment each point at different media. We plumb a multi-stage bank at the mains with a bypass, size the media to the test result, and test again after commissioning. The 18,000 base covers a standard multi-stage bank supplied and fitted; extra stages are quoted from the test.
The cartridge schedule is the part everyone skips: exhausted media is why "the filter stopped working" eight months later. We keep your schedule and remind you, and cartridges come at published markup. Bring your own system and it's a labor-only fit after we check flow ratings — and if your water tests clean, we tell you to keep your money.
6-Month Shield
Every installation is backed by a 6-month workmanship warranty.
Pay After Approval
You only pay once you have seen the work and approved it.
Upfront Pricing
We quote before we start. No hidden fees — the price we quote is the price you pay.
