San Diego has some of the hardest tap water in the country, and most homes have never had theirs checked. In one same-day visit, TapIQ tells you what's really in your water, what's safe, and whether you're wasting money on bottled water or the wrong filter.
People buy bottled water, pitcher filters, fridge filters, or expensive RO systems without knowing what problem they're solving. TapIQ identifies your concerns, screens your water, and recommends the right next step.
Bad taste or smell
Your water might be fine, or it might not be. Find out before spending money on filters.
Too much bottled water
A one-time check can replace an endless weekly water-buying habit.
No filter, unsure if you need one
Not sure if your tap is already fine? We help you decide with real data.
Renting, unsure what's installable
We recommend no-install, countertop, and reversible renter-friendly options.
Lead, PFAS, or old plumbing
Serious concerns deserve lab-confirmed answers. We'll coordinate testing.
Not sure if RO is worth it
RO isn't always necessary. We help you choose based on your actual water.
Slide to your household's habit. It usually adds up to more than a filter setup costs, and that's before you even know if you need one.
Estimate only. We'll right-size the exact setup for your home, budget, and lease.
Some setups overcorrect. Reverse osmosis and certain filters strip out beneficial minerals like calcium and magnesium, and a lot of bottled water is stripped or inconsistent too. The goal isn't the most aggressive filter, it's the right one: water that's genuinely clean and still balanced. Knowing what's actually in your water is the only way to get there, and that's exactly what we help you do.
A same-day, in-home water check that tells you exactly what's in your tap, in plain English. Sometimes a basic screening is all you need, and even if your water is already good, now you'll know for sure.
Moderate hardness, low chlorine. Under-sink carbon filter recommended. RO likely unnecessary.
No pressure, no confusing upsells. Choose what fits your home.
Take a short survey about your home, water habits, and concerns. No technical knowledge needed.
We check TDS, pH, hardness, chlorine, and other available screening parameters on-site.
You receive a plain-English explanation of what your results mean for your household.
We recommend pitcher, countertop, under-sink carbon, RO, or lab testing, whatever fits.
Most of our customers rent. We recommend no-install, countertop, and reversible options by default.
Find out if a simple filter can replace your weekly water habit and save you real money.
No dense lab jargon. You'll leave knowing exactly what your water contains and what to do about it.
We recommend what fits your home, budget, and lease, not the most expensive system.
Serious concerns? We connect you with certified lab testing for lead, PFAS, bacteria, and more.
We're not here to sell you an RO system you don't need. We help you make the smart call.
TapIQ is a team of San Diego water scientists with hands-on experience in water treatment around the world. We started TapIQ after seeing how often families overpay for bottled water or the wrong filter, simply because no one gave them a straight answer. Our mission is simple: honest, science-backed water screening so every home can access cleaner water, and the information to understand it.
"Clean water and clear information shouldn't be a privilege. Everyone deserves to know what's coming out of their tap."
Still unsure? Reach out. We're happy to talk through your specific water situation before you book.
Ask a QuestionThe Starter Check and Clean Water Starter Kit include field screening, not full certified lab testing. For concerns involving lead, arsenic, PFAS, VOCs, or bacteria, TapIQ can recommend and coordinate third-party certified lab testing.
Not always. Some homes only need better carbon filtration for taste and odor. Others genuinely benefit from RO, especially with concerns about dissolved solids or specific contaminants. TapIQ helps you choose based on your actual water, budget, and living situation.
Yes. TapIQ is designed with renters in mind. We can recommend no-install, countertop, reversible, or under-sink options depending on what your lease allows.
On-site screening may include TDS/conductivity, pH, hardness, chlorine, and select colorimeter-based checks depending on your concern. We use portable field equipment for a same-day read of key indicators.
Filter setup and RO installation options are coming soon or available by request. Some plumbing-related work may require a licensed installer. We'll clarify what applies during the consultation.
Tell us about your home and water concerns. We'll follow up to schedule your check. No pressure, no commitment required.
