Frequently Asked Questions.

Tap Score is the fastest way to get your water tested. We work with big and small labs all across the US, ensuring you always get the fastest, most relevant water test for your water.


Can I drop off my sample in person?

To ensure a high standard of quality control, even if you live next-door to a laboratory it is important that all sample logistics follow the same process. This is why we include Free Shipping, both ways with every order.

What is the fastest way to get help?

We are real humans. We want to help you as thoroughly and as efficiently as is possible. Having done this work for many years, we have found that Live chat support is usually the best way to answer most questions. We can share materials back and forth and we can clearly explain (and agree upon) complex things in writing. Yes, sometimes, phone calls are better—see below.

What is your phone number?


How fast do I get results?

You'll get results for most test panels in 3-5 business days after your samples arrive at the laboratory. Some tests can take longer. You can see estimated turnaround times (TAT) for all your orders inside your account and on each test kit's product page. Although rare, delayed results sometimes occur due to holidays, or particular issues with a sample or an instrument.

Is your laboratory certified?

Yes. If you have very specific FOA / compliance requirements though, please tell us in advance of your order so we can guide you to the appropriate options. There are literally thousands of nuances to laboratory certification and we will help you choose what you want if you have questions.

Reasons to test your drinking water

Before spending thousands on water treatment, ask yourself what are're actually treating. Understanding what's in your water can narrow your choices and save you money in the long run.

The age of our homes and pipes have a heavy impact on our water quality. Drinking water traveling through old pipes can pickup lead, copper and bacteria along the way.

Contaminants in our drinking water can cause everything from chronic illness to pregnancy complications and often exist without visible evidence. Testing is the only way to provide peace of mind.
