// For commercial plumbing contractors
AI for plumbing contractors, tested on reports your certified people already signed.
For plumbing contractors who test, install and service water, waste and gas piping in commercial, industrial and health care buildings. Start with backflow test reports, drafted onto each water purveyor's form from your tester's field notes, or with medical gas installer testing records for a hospital or clinic job. Either one runs as a free AI proof of concept on copies of 20 to 30 that your people already signed, and every signature stays theirs.

// Jobs we would test
Jobs that end with a certified person's signature
Backflow test reports
Each annual test of a building's reduced pressure, double check and vacuum breaker assemblies drafted from the tester's field notes onto the water purveyor's report form, with every missing reading, gauge accuracy date or license number listed for the certified tester who signs and files.
See the backflow reports pageMedical gas installer testing records
The installer's own tests on oxygen, medical air, vacuum and the other piped systems, drafted gas by gas from the crew's pressure logs, with brazing papers and blank witness or credential lines listed before the verifier is booked.
See the medical gas records pageGrease interceptor service records
Each pump-out or inspection of a commercial kitchen's interceptor written up the way the local grease program's form asks, with anything not measured on site listed for the technician.
Drain camera inspection reports
A video inspection of a building's drain or sewer line written up from the technician's footage notes: where along the run each observation sits and what was seen, for the technician to confirm.
// Why these two first
Certified tests come back every year, and each one is signed
Backflow testing follows the building, year after year. Washington's drinking water rule has each water purveyor keep at least one certified cross-connection control specialist. It counts hospitals, medical and dental clinics, laboratories, car washes, commercial laundries and mortuaries as high health hazard premises, whose service gets an air gap or a reduced pressure assembly, and it has each assembly tested when installed, repaired, reinstalled or moved, then every year. So a commercial customer list produces the same report over and over, and every one already filed is an answer key.
The model code says the same thing in its own words. Section 312.10.2 of the 2021 International Plumbing Code names reduced pressure, double check, pressure vacuum breaker, spill-resistant vacuum breaker and both detector fire protection assemblies, along with hose connection backflow preventers. Each is tested at installation, again right after a repair or relocation, and at least once a year, and the test gauges must meet ASSE 1064, the standard for backflow assembly field test kits.
The credentials split the work. ASSE's backflow certifications run from 5110 for assembly testers through 5120 for cross-connection control surveyors, 5130 for repairers, 5140 for fire sprinkler cross-connection control testers and 5150 for program administrators. A 5110 card is good for three years, and its practical exam has the candidate test ASSE 1013, 1015, 1020 and 1056 assemblies. The license, card and gauge details at the foot of each report are where a draft can list what is missing.
Medical gas has its own ladder. The 2024 edition of ASSE/IAPMO/ANSI Series 6000, released in March 2025 and aligned with NFPA 99-2024, the Health Care Facilities Code, keeps separate qualifications for installers (6010), inspectors (6020), verifiers (6030), bulk cryogenic supply verifiers (6035), maintenance personnel (6040) and designers (6060), and adds 6070 for design instructors. Installer, inspector and verifier hold different cards, so the installer's record has to be complete before anyone else reads it, and the records your foreman already signed are the second job's answer key.
Every purveyor writes its own forms. EPA's Cross-Connection Control Manual, first printed in 1973 and last corrected in 2003, says every municipality with a public water supply should run a cross-connection control program. Those programs are local, and many purveyors print a test report form of their own, which is why the test uses the forms of the purveyors you actually file with rather than a generic one.
One limit covers both jobs. Nothing in the proof of concept signs, certifies or files a test report, decides that an assembly or a test passed, prices or sends a quote, or contacts a customer, purveyor, verifier or inspector. It works only on copies. Which code edition applies and what it requires stay with your certified people and the authority having jurisdiction; these pages give no code advice.
// How the test runs
From signed reports to one decision
- Step 01
Pick the job, name the reviewer
The owner picks the reviewer: for backflow, usually the lead certified tester or whoever checks reports before they are filed; for medical gas, the ASSE 6010 foreman. The success criteria, a price range for the live job and the NDA are all settled in writing before anything is copied.
- Step 02
Run it on copies
You send 20 to 30 signed reports with the field notes, gauge photos and logs behind them. We call it the sandbox. Drafts come from the notes alone, then sit beside what your people signed. Where records can't leave the office, we build look-alikes with your reviewer.
- Step 03
About 30 days live, after a yes
New tests are drafted for roughly a month, and the certified person who did the work checks, corrects and signs each one before it goes anywhere. The second job, if you want it, gets its own yes and its own price.
Priced per job. You get a range before the proof of concept and a fixed price before you sign.
The range comes on the call, from how many assemblies your testers report on each year and how many purveyors' forms they use, or how many medical gas areas you test in a typical quarter.
