Before You Buy Any Water Treatment System in Central Ohio
Eight things every Central Ohio homeowner should know before spending a dollar on water treatment — including the red flags that cost people thousands.
The 8-Step Pre-Purchase Checklist
Work through these before you talk to any water treatment company — including us.
Get a water test first
Before talking to any company, know your baseline: hardness (gpg), iron (ppm), pH, TDS, and chlorine. A reputable company will test for free.
Know your household size and usage
System capacity is calculated from daily water usage. A family of 4 uses roughly 300–400 gallons per day. Undersized systems fail early.
Understand what you're treating
Hard water needs a softener. Iron needs an iron filter. Chlorine taste needs carbon filtration. PFAS needs reverse osmosis. One system doesn't fix everything.
Compare ownership vs. rental total cost
Get the 5-year total cost of any rental agreement. Compare it to the purchase price of the same system. The math almost always favors buying.
Ask about the warranty
Look for a 10-year warranty on the tank and a lifetime warranty on the valve. Shorter warranties signal lower-quality equipment.
Verify local service capability
Ask how quickly they can respond to a service call. A Columbus-based company with local technicians will always outperform a national chain.
Ask who manufactures the equipment
Request the brand name and model number. Look it up. Avoid private-label equipment with no manufacturer support.
Get everything in writing
Price, warranty terms, service commitments, and what happens if you move — all in writing before you sign anything.
6 Red Flags to Watch For
These are the warning signs that a water treatment company is more interested in a sale than in solving your problem.
They quote a price before testing your water
A system sized without a water test is a guess. You may end up with a unit that's too small (fails quickly) or too large (wastes salt and water).
They push a rental/lease agreement
Leasing sounds affordable but costs $3,000–$4,800 more over 5 years than buying. You never own the equipment and can't take it with you if you move.
High-pressure same-day sales tactics
Legitimate water treatment companies don't need to pressure you. If a salesperson says "this price is only good today," walk away.
They can't name the brand of equipment
Some companies install private-label equipment with no manufacturer warranty. Ask for the brand name and look it up.
No local service address
National chains often have limited local technicians. Ask where their nearest service center is and what the average response time is for service calls.
They don't ask about your household size
System capacity must be matched to your household's daily water usage. A system sized for 2 people will fail quickly in a household of 5.

Frequently Asked Questions
Should I test my water before buying a water softener?
Yes — always. A water test tells you your actual hardness level, iron content, and other contaminants. Without a test, you risk buying a system that's undersized, oversized, or wrong for your specific water chemistry. Pure Aqua Columbus provides free water tests with no obligation.
What is the difference between renting and buying a water softener?
Renting (leasing) means you pay a monthly fee indefinitely and never own the equipment. Buying means you own the system outright. Over 5 years, renting from companies like Culligan typically costs $3,000–$4,800 more than buying — and you have nothing to show for it at the end.
What should I ask a water treatment company before buying?
Ask: Do you test my water before recommending a system? Is the system sized for my actual hardness level? What is the warranty and who services it? Are there monthly fees? Is the equipment brand-name or private label? See our full list of questions at /compare/questions-to-ask.
How do I know what size water softener I need?
System capacity is calculated from your water hardness (gpg) multiplied by your household's daily water usage (gallons). A reputable company will calculate this from your water test results and household size — not from a price sheet.
Is Pure Aqua Columbus a local company?
Yes — Pure Aqua Columbus is locally owned and operated in Central Ohio. We've been serving Columbus-area homeowners since 2018. We're not a franchise or a national chain with a local phone number.
