Serving San Diego County

Do you actually know what's in your tap water?

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.

The Problem

Most people guess when buying a water 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.

01

Bad taste or smell

Your water might be fine, or it might not be. Find out before spending money on filters.

02

Too much bottled water

A one-time check can replace an endless weekly water-buying habit.

03

No filter, unsure if you need one

Not sure if your tap is already fine? We help you decide with real data.

04

Renting, unsure what's installable

We recommend no-install, countertop, and reversible renter-friendly options.

05

Lead, PFAS, or old plumbing

Serious concerns deserve lab-confirmed answers. We'll coordinate testing.

06

Not sure if RO is worth it

RO isn't always necessary. We help you choose based on your actual water.

What are you really spending on bottled 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.

The part most people miss

Cleaner water isn't just about removing things.

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.

Main Offer

Clean Water
Starter Kit

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.

You might not even need a filter, and that's a great answer. A check is still worth it: peace of mind if you're breastfeeding or mixing formula, answers on hard water, or finally knowing why your water tastes or smells off. The report is the point, not a filter sale.

FAQ

Common questions

Still unsure? Reach out. We're happy to talk through your specific water situation before you book.

Ask a Question

The 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.
