Each backflow test drafted onto the purveyor's form, with every gap listed for your tester.

Picture a tester's morning at a medical office building: a reduced pressure assembly on the domestic service, a double check detector on the fire line, a pressure vacuum breaker on the irrigation. Readings go onto a test sheet or a tablet, the gauge and each nameplate get photographed, and the truck moves on. Later someone in the office types each assembly onto the form of the purveyor serving that address and chases the tester for whatever is blank before it can be signed and filed.

In the proof of concept, AI does that typing from the same notes and photos: one draft per assembly, laid out the way that purveyor's form is, plus a list of what the notes leave out. It never signs a report, marks a pass or files anything. Your reviewer sets each draft beside the one your tester signed, box by box.

The form sets the order of the work. Texas's version, form TCEQ-20700, is meant to be filled in at the assembly while the test runs, and an electronic copy counts only if the tablet was there too. Each assembly gets its own form, and a retest by a different licensed tester goes on a separate one. It names six assembly types (RPBA, RPBA-D, DCVA, DCVA-D, PVB and SVB), wants the old model and serial number when an assembly was replaced, and only fits a Type II detector assembly with a single check bypass. On a double check, the second check needs a number, not just a box. The licensed tester signs the printed original for the public water system unless the commission has approved electronic recordkeeping, and records are kept at least three years.

Washington asks for things Texas doesn't. Its report rule, in force since January 2014, wants the downstream hazard in the state's own categories when the tester knows it, whether the air gap under a reduced pressure assembly's relief valve meets the requirement, and any missing or defective part, shutoff valves and test cocks included. It also wants the tester's department-issued certification number, a statement that the tester personally inspected and field tested the assembly, and a signature that may be original, a copy, a fax or electronic. A draft built for one state's form leaves holes on another's, so the success criteria name every form in your sample.

The gauge is part of the record. Texas wants the differential pressure gauge's make, model, serial number and accuracy date on every report, an accuracy check each year, and a gauge used on potable assemblies kept off non-potable ones; the form asks which kind the gauge serves and whether the assembly sits on an auxiliary supply. Washington asks for the date of the kit's latest laboratory accuracy check or calibration. EPA's manual describes the instrument as a differential gauge with a 0 to 15 psi range and a 500 psi working pressure. When a sheet names the kit but no accuracy date, the draft lists the date as missing instead of carrying last year's forward.

Procedures and credentials change under your testers. Texas bases its tester license on the field test procedures in the USC Foundation for Cross-Connection Control and Hydraulic Research's Manual of Cross-Connection Control, Tenth Edition, first printed in December 2009. The Foundation's fifth printing, dated 2020, corrected errors in Appendix A that it says also appear in its laminated field test procedures dated 2020.01.15. In California, testers used by public water systems need certification from an organization the State Water Board recognizes from July 1, 2026, and from July 1, 2027 only from organizations accredited by ANSI to ISO/IEC 17024; the board recognized ASSE 5110 in a letter dated June 17, 2025. The draft prints the license your office has on file and lists one with no number or a past expiry, leaving whether it is acceptable to your tester and the purveyor.

Field notes are rarely tidy. EPA's manual has the tester get the owner's permission before shutting the water off, warns that hospitals and continuous process plants can't lose supply without a planned, coordinated shutdown, and offers two assemblies in parallel as one way to keep water flowing. On a reduced pressure assembly it says to wait a moment before connecting hoses, since water from the relief valve probably means a fouled first check and the test can't go on until it is serviced. So a real sample holds postponed tests, repairs and retests on a later visit; the draft keeps the initial test apart from the test after repair and copies each part as written. Your reviewer will look first at readings in the right boxes for the assembly type, serial numbers that match earlier reports, complete kit and license details, and any box filled where a gap should have been listed.

After your reviewer's yes, new tests are drafted for about 30 days as testers turn in their notes.

Each draft goes back to the tester who did the work. They fix it, make the pass or fail call, sign it and file it through the purveyor's portal or by mail, the same as today. No draft reaches a building owner or a purveyor on its own.

The live job carries a fixed price agreed after the test. Medical gas testing records, or any other job, are priced separately, and monthly support begins once a job is live.
