Why Homeowners & Restaurant Managers Use FlowComply Directory

Official municipal water utility PDF lists mix commercial-only fire contractors (who quote $450–$600 to discourage 15-minute residential backflow tests) with independent residential-friendly specialists who charge $55–$95. We verify which pros actually accept single-family residential jobs, offer 24/7 emergency grease trap pumping, and submit electronically to portals like SwiftComply, WEIRS, TMWA, and NYSDOH.

FREE · NO CREDIT CARD

Free Backflow Test & Grease Trap Due-Date Reminder

Tell us when your last backflow test or grease trap pump-out was and how often it’s required. We’ll email you a confirmation now, then a reminder about 30 days and again about 7 days before the next one is due (for pump-outs every 45 days or less, just the 7-day reminder) — so you don’t get hit with a late notice, fine, or water shutoff.

For providers: get exclusive quote-form leads in your city ($149/mo bundle).
