Free Service

Free In-Home Water Test

Before recommending a single system, we test your water — at the source, at the cistern, and at the tap. This tells us exactly what your home is dealing with: TDS, hardness, chlorine, pH, and bacterial indicators.

It takes less than an hour. There is no cost and no obligation. You walk away with hard numbers, not a sales pitch.

Done Right the First Time

Installation

Professional installation of whole-house, RO, and UV systems by our own technicians. Every install includes commissioning, bypass valves, and pressure gauges so you can isolate the system for maintenance without cutting your water supply.

We tie in before your pila so filtration happens before water enters storage, run a full leak check, and verify flow rate and pressure drop before we leave.

Keep It Running

Maintenance & Service

Scheduled filter changes, UV lamp replacement, and full system inspections. Pick a plan that matches your household — annual, semi-annual, quarterly, or monthly visits.

We track your service schedule, bring the cartridges, and leave a written report after every visit. No more guessing when filters were last changed.

Stocked Locally

Filter Replacement

Genuine iSpring cartridges and parts stocked in Rosarito. Sediment filters, GAC and KS carbon blocks, RO membranes, alkaline post-filters, and UV lamps — for your home, apartment, or property management portfolio.

If you’re on a maintenance plan, replacements are scheduled and included. If you self-service, we ship or hand-deliver locally so you don’t wait on cross-border shipping.

Fix What Isn't Working

System Repairs

Slow flow? Strange taste? Pressure drops? We diagnose and repair water systems — including ones we didn’t install. We work with most major brands, including iSpring, Pentair, and VIQUA.

We’ll inspect what’s in place, identify the failed component or root cause, and put together a repair plan. No tear-out unless it’s actually needed.
