Questions testers actually ask.

Straight answers about how Potaflow works.

When I hit submit, does it go directly to the water district?
Yes, automatically. Potaflow detects the correct water district from the site address, generates your DOH-1013 PDF, and delivers it instantly. If the district has a Potaflow portal, it goes there. If not, Potaflow sends the form to the district via email on your behalf with a timestamped delivery record. Either way you have proof of submission.
Does the customer get notified after I submit?
Only if your company has opted into customer email notifications, it's not on by default. You're in control of whether your customers receive a copy.
What happens if a district rejects my form?
You'll see the rejection and the district's notes in your dashboard. From there you can submit a corrected version it opens the original form pre-filled with your data so you don't have to start from scratch. The corrected version replaces the original in the compliance record.
What do I need to sign up?
Just your name, email, and a password. No certification number at registration. Your NYS certification number and test kit info are entered when you start your first form. Signup takes under 2 minutes.
Which water districts does Potaflow support?
Potaflow delivers to every Nassau County district that accepts the DOH-1013 by email. You can see the current list on this page, and it updates automatically as districts are added. Your form is routed to the right district by the site address, with a timestamped delivery record. If yours isn't listed yet, contact us and we'll add it.
Do I still need to send a paper copy?
No. These districts take the DOH-1013 by email, and Potaflow's timestamped delivery record is your proof of submission. You can download and print your PDF from your dashboard anytime if you want a copy.
Does it work on my phone in the field?
Yes, Potaflow runs in any modern browser, no app store download required. Works on phone, tablet, or desktop. Forms auto-save as drafts so if you lose connection mid-form, your data isn't lost. Submissions queue and retry automatically when you're back online.
Is it really free? What's the catch?
It's free while we get the first testers on board, no hidden fees. When we start charging it's $99 a year. No per-test fees, ever. Sign up now and that rate is locked in for as long as you stay subscribed.
Is Potaflow only for Nassau County?
Right now yes, Potaflow is built specifically for Nassau County, NY and the DOH-1013 form. Other New York counties and states are on the roadmap. If you're outside Nassau County but deal with DOH-1013 submissions, reach out we want to hear from you.
What happens to my data if I stop using Potaflow?
Your submission history and PDFs are always accessible from your dashboard. You can download your records at any time. Your data is encrypted in transit and at rest on AWS infrastructure.
