Custom Engineering
We engineer every system from scratch based on your water chemistry, your home, and your household — never a generic package solution.
Why Custom Design Matters
Walk into any big-box store and you'll find water treatment packages designed for a statistical average. The problem is that Southwest Florida's water chemistry varies dramatically — from city water in Sarasota with 18 gpg hardness and elevated chlorine, to private wells in Parrish with iron at 4 mg/L, hydrogen sulfide at 0.5 ppm, and pH at 6.2. A system that works perfectly in one home can be entirely wrong for another home three miles away.
Our design process starts with measurements and ends with a system sized precisely for your conditions. We consider your water chemistry results, the number of people in your home, your daily water usage patterns, your plumbing configuration, your installation space, and your budget — then we engineer a solution that addresses your specific issues without over-engineering (and overcharging) for problems you don't have.
We also consider the future. If your water chemistry is borderline on bacteria (as many shallow Florida wells are), we design with a UV sterilization stub-out so adding UV later is easy and affordable. We think about your system as a long-term investment, not a one-time sale.
What's Included — Free
“Three other companies gave us generic quotes over the phone. Convenient Water came out, tested our water, walked through our whole house, and designed a system specifically for our well chemistry. The proposal explained exactly why they recommended each component. No other company did anything like that.”
— Robert & Linda H., Parrish
Our Design Process
A rigorous, thorough process that takes the guesswork out of water treatment.
Every design starts with a comprehensive water test. If you haven't had one, we schedule it first — free of charge.
Our technician tours your home, evaluates plumbing entry points, assesses space, checks water pressure, and takes measurements.
We discuss your household size, water usage habits, any current water quality concerns, and your priorities — performance, eco-friendliness, low maintenance, or budget.
Back at the office, our technical team runs sizing calculations to spec the exact system your water chemistry and household require. No guesswork.
We return (or schedule a call) to walk you through 2–3 options with clear pricing. We answer every question without rushing. You take all the time you need.
There is no pressure and no deadline. We leave the written proposal with you. When you're ready to move forward — or if you have questions — we're here.
Assessment Scope
Our design consultation is thorough because a thorough design prevents problems later.
Full 12-parameter water test establishes the baseline — hardness, pH, iron, TDS, chlorine, sulfur, bacteria, and more. Every design decision flows from this data.
We assess your pipe material (copper, CPVC, PEX), main entry point, available installation space, water pressure (PSI), and electrical access near the proposed installation location.
We calculate your peak daily demand based on occupants, bathrooms, appliances, and usage patterns. Undersized systems underperform; oversized systems waste salt and water.
Using your water chemistry data and household profile, we calculate the exact grain capacity, flow rate, tank size, and media volume required for optimal performance.
We present 2–3 system configurations at different price points — a baseline solution, a mid-range option, and a premium comprehensive system — with transparent pricing for each.
You receive a written proposal within 24 hours of the consultation that includes system specifications, installation scope, warranty terms, and financing options.
System Design FAQs
The initial site assessment and consultation typically takes 60–90 minutes. This includes the water test, home walk-through, usage discussion, and preliminary recommendations. We then prepare the written proposal within 24 hours and can present it in person or by phone, whichever you prefer.
Yes, completely free. The water test, site assessment, usage evaluation, engineering work, and written proposal are all provided at no charge. There is no obligation to purchase anything, and there is no time pressure.
Absolutely — well water design is one of our specialties. Florida well water often has multiple simultaneous issues (iron, sulfur, bacteria, hardness, tannins) that require a carefully sequenced multi-stage treatment system. The order in which treatment stages are arranged matters significantly for well water, and our engineering team has designed hundreds of well water systems throughout Sarasota and Manatee Counties.
Yes. We regularly design system additions and upgrades around existing equipment. If you have a softener but want to add RO drinking water, or you have a whole-house filter that needs to be re-specced for your current water chemistry, we can assess what you have, identify gaps, and propose targeted solutions rather than replacing everything unnecessarily.
Yes — we offer full commercial system design for restaurants, hotels, medical offices, car washes, laundromats, manufacturing facilities, and other commercial applications. Commercial design typically requires additional data gathering including water usage logs, regulatory requirements, and equipment specifications. Learn more on our Commercial Services page.
