Scope & Partner Routing

    What we do — and what we don’t

    FLOW does the water-side of water-based fire protection: standpipe flow tests, hydrostatic pressure tests, fire hydrant flow tests, fire pump flow tests, in-service tank inspection by an underwater submersible drone (ROV), and bulk water for pool fills. We do not work on sprinkler systems, install or design systems, service alarms or extinguishers, or issue engineering stamps — and when a job needs those, we route it to a licensed fire protection firm partner. Staying in our lane is why our testing is good.

    What we do

    • Standpipe flow tests

      NFPA 14/25 flow testing at system demand from the hydraulically most remote outlets, with pumper apparatus.

    • Hydrostatic pressure tests

      200 psi / 2-hour (or 50 psi above max) integrity testing on standpipes and applicable piping.

    • Fire hydrant flow tests

      Static, residual, and pitot GPM to NFPA 291 for private hydrants and water-supply verification.

    • Fire pump flow tests

      Annual flow tests at minimum, rated, and 150% flow where a fire pump is present.

    • In-service tank inspection

      Fire water tanks inspected while they stay full and in service, using an underwater submersible drone (ROV). The tank stays full and in service.

    • Bulk water for pool fills

      Hydrant-direct bulk water delivered by pumper for pool fills.

    What we don’t

    • System design or installation

      We do not design or install standpipe, sprinkler, or fire-main systems — that is NFPA 13/14 installation work for a licensed installer. We test what is already in service.

    • Sprinkler inspection, testing & maintenance (ITM)

      FLOW does not do sprinkler inspection or ITM and does not work on sprinkler systems. Sprinkler inspection, head replacement, and maintenance are routed to a licensed fire protection firm partner.

    • Fire alarm & electrical

      We do not inspect, test, or service fire alarm panels, detection, or electrical systems. Different discipline, different license.

    • Fire extinguishers & suppression

      We do not service portable extinguishers or clean-agent/kitchen suppression systems.

    • Engineering stamps & hydraulic design

      We provide measured field data; a licensed professional engineer provides stamped hydraulic calculations and design certifications.

    • Final AHJ sign-off & code authority

      We are not the authority having jurisdiction and do not issue approvals. FLOW produces and sends the report for the tests it performs; approval stays with the AHJ.

    How partner routing works

    When a job needs work outside the water-side — a stamped hydraulic calculation, sprinkler inspection or ITM, a fire alarm inspection, or an installation — we do not force it or fake it. We do the water-moving fieldwork and capture the measured data, and FLOW produces and sends the test report. A licensed fire protection firm partner handles the stamps or scope we do not cover.

    For the building owner that means one call still gets the job moving: we run the test, and the right licensed party closes it out. You get accurate field data and a clean handoff instead of a vendor pretending to do everything.

    Why we stay in our lane

    Specialization is why our testing is good. The water-side of fire protection — moving real water at real pressure and proving a system delivers — is a distinct discipline that needs pumper apparatus, the right gauges, and crews who do it every day. Firms that try to be everything to everyone rarely do the hard, physical water tests well.

    It is also honest. Telling you plainly what we do not do turns a mismatched inquiry into a useful referral and a partnership, instead of a bad fit and a wasted visit. Buyers, AHJs, and insurers trust a vendor who knows exactly where its scope ends.

    Not sure who you need?

    Tell us what you are trying to accomplish and we will point you to the right test — or the right partner. If it is water-side, we run it. If it is not, we will tell you who does and, where we can, make the introduction.

    Scope, answered

    What does FLOW do?

    FLOW performs the water-side of water-based fire protection testing: standpipe flow tests, hydrostatic pressure tests, fire hydrant flow tests, fire pump flow tests, in-service tank inspection by an underwater submersible drone (ROV), and bulk water for pool fills. These are the flow-and-pressure tests that prove a system actually delivers water, performed with pumper apparatus sized to real system demand.

    What does FLOW not do?

    We do not work on sprinkler systems, and we do not do sprinkler inspection or ITM. We do not design or install fire protection systems, service fire alarms or electrical, service extinguishers or suppression systems, issue engineering stamps, or act as the authority having jurisdiction. Sprinkler work is routed to a licensed fire protection firm partner. For the tests FLOW performs, FLOW produces and sends the report.

    Do you install or design fire protection systems?

    No. Design and installation are NFPA 13/14 work for a licensed installer or engineer. FLOW tests systems that are already in service — we prove existing standpipes, hydrants, pumps, and mains still perform, and we hand off design or installation needs to the right licensed party.

    Do you perform full fire sprinkler inspections?

    No. FLOW does not perform sprinkler inspection or sprinkler ITM, and FLOW does not work on sprinkler systems. Sprinkler inspection, testing, head replacement, and maintenance go to a licensed fire protection firm partner. FLOW tests the water side: hydrant flow, standpipe flow and hydrostatic tests, and fire pump flow.

    Can you sign off or submit to the AHJ?

    FLOW provides the measured field data and produces and sends the test report. Where a job requires an engineering stamp, that is routed to a licensed fire protection firm partner, because FLOW does not issue stamps.

    What do you refer out, and to whom?

    We refer out system design and installation, fire alarm and electrical, extinguisher and suppression service, and stamped engineering calculations. These go to licensed fire protection firms and professional engineers we work with, so a job outside our water-side scope still gets to the right hands quickly.
