One flat monthly price. No $5-per-report fees, no juggling ten different water district portals. Test in the field, even offline — BackflowFiler builds the report and gets it where it needs to go.
If any of this sounds familiar, BackflowFiler was built for you.
Ten water districts, ten different logins, ten different form formats — and you have to remember every one.
Your current software charges per report. The more tests you run, the more it eats your margin.
No signal in the basement or the vault, so it's back to paper — then re-typing everything at the office.
Clients forget until a shutoff notice shows up — and then it's an emergency call, not a booking.
Enter readings on your phone, even with no signal. Photos and a signature save right to the record.
Formatted to that specific water district's requirements — no more guessing which form they want.
One click sends it where the district accepts email, or a ready-to-paste packet for their portal.
No cell signal in the vault? Every test saves locally and syncs the moment you're back online.
We track how each water district wants reports and get yours there in the right format.
Automatic emails 30–60 days before the annual test is due, so you get the booking, not a surprise.
Send an invoice right after the test and get paid by card — no separate billing software.
We remind you before your license and gauge calibration expire — so your reports never get rejected.
Every PDF matches the exact form and naming convention your water district expects.
Test one assembly or a thousand — the price doesn't change.
Locked in for life. Price rises to $79/mo once the first 50 spots are filled.
Running 100 tests a year at $5 a report costs $500+ before you've paid for the software itself.
We're onboarding a small group of testers in Washington and Oregon first. Leave your email and we'll reach out before we launch in your area.
No spam. One email when we're ready for your city.
"I built BackflowFiler after watching testers lose margin to per-report fees and lose evenings to city portals. If that's your week too, I'd like to hear about it."
